Abstract Planetary Nebulae (PN) represent a critical stage of stellar evolution which is still poorly understood. We still lack reliable observational estimates of stellar luminosity, mass, effective temperature and age, which could be used to constrain evolutionary models, and determine key data such as mass-loss rates, He shell flash phases and the role of dredge-up. This proposal represents the first stage in a systematic and definitive study using HST observations, which will require approximately a further 150 hours for completion, of a large sample of nebulae at known distance in the Magellanic Clouds. The following observations allow us to derive all parameters needed for proper confrontation between theory and observation: \* Direct PC imaging to detect central stars and to derive the physical dimensions, masses, ages, and spatial structure of the nebulae. \* FOS spectrophotometry of the central stars and nebulae in the range 1150 - 2332 Angstroms. This data will be used in combination with stellar models to derive the effective temperature, bolometric luminosity, and mass of each of the exciting stars. The combination of these parameters with the dynamical age of the PN will define the evolutionary tracks in the Luminosity/T-eff diagram. We will use two independent ionisation codes to interpret the FOS spectra, optical and IR spectra, and the ionisation structure derived from the PC images. This analysis will yield chemical abundances of many elements, including the astrophysically important species He, C, N, O, and Si. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Dopita MOUNT STROMLO AND SIDING SPRING AUSTRALIA OBSERVATORIES Page 3 ------------------------------------------------------------------------------------ 3. Description of proposed observations. Imaging Program: The Magellanic Cloud PN range in size from 0.05 - 4.0 arcseconds, with a typical size of about 0.6 arcseconds (Jacoby 1980; Wood, Bessell and Dopita 1986; Wood et. al. 1987). Consequently, they are ideally suited for imaging with the PC camera. Our Cycle 1 [O III] 5007 Angstrom (F502N) images are designed to give a typical signal to noise of 20 per pixel to provide data on angular diameters and nebular morphology (spherical,bipolar, multiple shell, etc.), which in conjunction with our ground-based [O III] expansion velocity measurements will provide a dynamical age model. Cycle 2 UV Spectrophotometry: We are undertaking in Cycle 2 FOS spectrophotometry in the range 1150 - 3200 Angstroms using the G130H, G190H and G270H gratings. We aim to achieve an average signal to noise in the nebular continuum of 3 per pixel. Since it proves to very inefficient to do separate AQU/PEAK for both the blue and red sides of the spectrograph, we have elected to observe on the blue side only, accepting the lower efficiency in order to have data in the G130H bandpass. Since the Magellanic Clouds are close enough that even the faintest PN can be detected, the flux and spectral distribution of the PN nuclei can be measured over their entire ~5 mag in luminosity. Our aim is to accomplish this objective, and to achieve a good detection of the central star against the nebular continuum, even when the stellar flux is only 10% of this nebular continuum. This objective will also ensure that uniform, high quality, high dynamic range nebular spectra are obtained for the full range of nebular conditions. For the purposes of computing exposure times for spectra, a mean extinction E(B-V) of 0.15 and an LMC or SMC-like extinction law have been assumed. The counts/diode/second C-d, is given in terms of the flux at 1650 Angstroms (F_1650):log(C_d) =- f(Phi) C + log(F_1650), where C has the values 13.53 (G130H, blue digicon) and 13.56 (G190H, blue digicon) and 14.10 (G270H,again the blue digicon). The function f(Phi) is a function of the diameter of the PN, accounting for spherical abberation and is calculated from a modelling of the PSF and the PN. These data will be combined with our ground-based data of comparable quality covering the wavelength range 3200 - 10000 Angstroms. In the decade of frequency covered by these observations, we will see emission lines of the astrophysically important elements such as He, C, N, O, Si and S in the full range of ionisation stages expected to be present in the nebula. For this reason, and also because the allowable nebular models are strongly constrained by the imaging results, we expect that the chemical abundances we will derive will be much more accurate than any previously obtained.

J., 320, p. 178 Following initial PIT review, this cycle 2 proposal (GO3441) was modified to update acquisition and science procedures (December 1992). The observations of LMC-SMP85 have been deleted from this proposal as they are being conducted under the Cycle 1 proposal GO4040. As all observations are being conducted on the blue side, obsolete definitions referring to the red side have been deleted from the exposure logsheet. Similarly, new definitions have been added to define the new acquisition methods described below. Most PEAK_UP acquistions have been converted to BINARY acquisitions as nearly all targets in this sample were observed with PC8 (GO2266) to be smaller in size than a FOS diode width (0.35 arcsec). New acquisition exposure times have been derived using the FOS Exposure Time Simulator, using ground-based optical spectra, and generic UV photoionisation models, as input. For those targets larger than a FOS diode width (LMC-SMP35, LMC-SMP87), a 5x5 PEAK-UP acquistion, with 0.5 arcsec steps using the 1 arcsec aperture, will be performed. This gives an effective field coverage of 3x3 arcsec, and will achieve 0.25*(2**0.5) = 0.35 arcsec accuracy on any PN within 1.25 arcsec of the initial pointing position. Finally, a PEAK-UP acquisition in the [OIII] 5007 Angstrom line is required for LMC_SMP20 (using the G570H grating), as it is in a relatively crowded field with neighbours of greater brightness in V. No offset star could be found for which we could determine sufficently accurate V and B-V. All target coordinates have been updated using re -measured positions from GSSS. COMMENT lines in the exposure logsheet have been updated to include relevant GSSS information for each target. An ACQ mode exposure has been added after each target acquisition to record the final pointing position. Page 4 ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The angular diameters of the Magellanic Cloud PN line in the range 0.05 - 4.0 arcseconds, ideally suited to the HST capabilities. the dimensions or morphologies of these objects cannot, in general, be obtained from the ground. Preliminary ground-based work has been done, as far as it is possible, using direct imaging and image reconstruction (Jacoby 1980; Wood et. al. 1987) or speckle interferometry (Wood, Bessell, and Dopita 1986). However, imaging resolves only the largest, and speckle interferometry resolves only the brightest nebulae, leaving the vast majority of objects unresolved. Some of us have obtained low resolution UV spectra of a few of these objects using the IUE satellite. However, only the brightest objects are observable, many of the same objects chosen for the GTO program. The UV data is crucial for measurement of the stellar flux distribution and to obtain densities and ionic abundances for dominant ionisation stages of many elements. Only the combination of high resolution and a spectral range which extends shortward of the peak in the hydrogen two-photon nebular continuum (about 1450 Angstroms) will enable us to detect the star in the cases where the nebular continuum is strong. Our HST program is supported by a comprehensive and continuing ground-based program. We have used the 1-metre, 2.3-metre and 3.9-metre telescopes at Siding Spring to measure fluxes, sizes, expansion velocities, radial velocities and nebular spectra from 3200 to 10000 Angstroms. These observations already provide an excellent set of homogeneous and high-quality data which gives the best possible ground-based characteristics of the Magellanic Cloud population of PN. this data set will allow us to extend our population classifications from the HST subset to the entire population of PN in the Magellanic Clouds.

J., 320, p. 178 ------------------------------------------------------------------------------------ 6. Description of special calibration exposures. As high-quality astrometric determination of the nebular centroid will be obtained on the basis of the PC images, we may seek to give an improved estimate of the position based on these data, for input to the Cycle 2 spectroscopy program. The spectroscopic observations are required to be non-interrupted because we need to be sure that the same part of the nebula is being observed in all three spectral bands. This is a requirement for the spectrophotometry to be valid. Page 5 ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. All PC images and FOS spectra will be reduced at STScI and then distributed by H.Ford and R.Bohlin to the team members. The dynamical ages of the nebulae will be derived by creating models of expanding prolate shells with varying azimuthal intensities whose projections onto the sky reproduce the [O III] line profiles (already obtained for the whole sample, Dopita et. al. 1985, 1988) and the PC image structure. The software needed for this program has already been written by H.Ford and his collaborators. We plan to combine the FOS UV spectrophotometry with ground-based and near-IR spectrophotometry to produce dereddened spectra. Theoretical models of the nebular continuum and of the central star will be used to separate the two continuum contributions and to place the star on the L-T(eff) diagram. By using the dynamical age already obtained, we will compare the evolutionary tracks implied for the PN nuclei with the theoretical evolutionary models (e.g. Wood and Faulkner 1986). This will enable us to determine the mass distribution of the PN nuclei, to determine whether PN ejection occurs at the time of the Helium shell flash, and to put strong observational restraints on the post-AGB mass-loss. Using the observed parameters of the central star, the FOS spectrophotometry and ionisation structure implied by the PC images, we will construct detailed photoionisation models using independent codes by Harrington, and by Dopita and Binette. The nebular size and structure, the shape of the stellar spectrum, and the ratio of stellar to nebular continua will enable us to obtain the mean ionisation parameter (Q), the ionisation temperature (T*), and the optical thickness of the nebula, which together define the nebular model. The FOS spectra are vital in the determination of the abundances of the dominant ionic species of N, C and Si. Likewise the ratio of the C III] doublet at 1906, 1909 Angstroms will give the electron density in the region of the PN containing the dominant ionisation stage. From the complete spectrophotometric data we will be able to derive the abundances of the elements : He, C, N, O, Ne, S, Cl, and Ar and possibly, Mg, Fe and Ni as well. We wish to stress that the PC nebular images and the wealth of FOS ultraviolet data will enable us to construct models with a level of detail which has previously been obtained in only a few Galactic PN such as NGC7662 (Harrington et. al. 1982), and IC3918 (Clegg et. al. 1987).
