We propose to image Alpha Ori in the ultraviolet continuum and chrom line_3: ospheric emission of Mg II using the FOC, and also to spectroscopically image th line_4: e star and its extended atmosphere in the Mg II emission lines in order to estab line_5: lish the ultraviolet diameter and limb-darkening, to discover the extent of the line_6: chromosphere, to detect surface and atmospheric features and to determine the dy line_7: namics of the atmosphere. line_9: This program will utilize the capability of the HST after correction by COSTAR t line_10: o produce the first direct, resolved ultraviolet image of a star other than the line_11: Sun. These observations will showcase the unique capability of HST for high res line_12: olution imaging and provide more direct constraints on the physical processes re line_13: sponsible for the structure of extended atmospheres than has been possible previ line_14: ously. Obtaining a high-fidelity image of Alpha Orionis in the ultraviolet will line_15: establish a new area of stellar physics research. ! ! end of abstract general_form_proposers: lname: GILLILAND fname: RONALD mi: L inst: 3470 country: USA ! lname: DUPREE fname: ANDREA mi: K inst: 2166 country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: FOC direct images. Using crossed F220W+F278M+F4ND will provide an image in whic line_2: h about 18% of the counts arise from MgII emission with a diameter of 0.2-0.6", line_3: 77% of the counts come from continuum within +/-200A restricted to a diameter of line_4: about 0.1" and a 5% visible light leak from wavelengths beyond 3000A. line_5: Use will be made of the 128X128 IMAGE mode for its superior dynamic range that line_6: will allow linear response imaging of the photospheric contribution at about 2.4 line_7: counts/s/px in the central 40 pixels. The more extended MgII yields 0.034 cts/s line_8: /px if extended over a 0.4" disk. The F220W+F253M+F4ND exposure will provide line_9: a pure continuum image at half the count rate of F278M. This will be used to line_10: allow clean separation of the photosphere and chromospheric images, i.e., off line_11: and on band of MgII. A point spread function calibration is specified using line_12: a warm white dwarf. This high S/N PSF determination with central pixel count line_13: rate of 2.3/s from a point source will be essential for supporting direct line_14: modeling and deconvolution analyses of the Alpha Ori observations. ! question: 3 section: 2 line_1: GHRS tomographic images. Through use of the SSA aperture as an occulting edge line_2: a series of spectra taken with successive telescope offsets can provide all of line_3: the information necessary to reconstruct a spatially resolved image at each ind line_4: ependent spectral resolution element. Taking 24 quarter-stepped spectra offset line_5: by 0.0275" along each leg of a "+" centered on the star will provide resolved line_6: strips 0.72" long with the 0.22" width of the SSA. The corners will be line_7: mapped with a second 2 line SPATIAL SCAN, and combining information from the line_8: FOC images and GHRS tomography will allow robust interpretation in 2-D. line_9: Target acquisition is dominated by continuum light so there is no problem line_10: obtaining a well centered set of telescope pointings. line_11: A point spread function observation will also be acquired using a well-calibrat line_12: ed UV standard to calibrate the GHRS spectral tomography. ! question: 4 section: 1 line_1: Not needed for phase II. ! question: 5 section: 1 line_1: As stated in the Phase I proposal we have been awarded (AKD) observing line_2: time for a period spanning 3 years (through April 1995) in order to continue line_3: the monitoring of Alpha Ori in the ultraviolet. The ultraviolet spectroscopy line_4: program is accompanied by optical photoelectric photometry at Villanova line_5: Observatory and radial velocity measurements at the McMath Telescope at KPNO. line_6: Thus we will be able to determine the state of the star when the HST line_7: observations are made, and request that they be carried out contemporaneously line_8: with the IUE monitoring program. Optimum times (provided IUE is still in line_9: operation) are: Sept-Nov '94 or Jan-March '95. If IUE is turned off on line_10: Sept 30th, 1994 as rumored, then we wish the observations to occur Sept 94. line_11: REAL-TIME contacts are required for the FOC observations. The brightness of line_12: Alpha Ori, and our desire to use the 128X128 IMAGE mode force real-time line_13: contacts to: 1) verify filter positions before a slew to the target can be line_14: made, and 2) to perform an interactive acquistion to center the target for the line_15: 1.8" square 128X128 IMAGE field. line_16: Observation in a second filter requires a telescope offset and a real-time line_17: telemetry verification of filters, but will not require a second interactive line_18: acquisition. ! question: 6 section: 1 line_1: Observations of HZ4 (FOC) and ETA-UMA (GHRS) are in reality simply special line_2: calibrations to define very precisely the PSF for these two instruments. line_3: The HZ4 and ETA-UMA observations should be public domain as soon as obtained. ! ! question: 8 section: 1 line_1: As noted in Sec. 5 we wish the observations to be coordinated with an ongoing line_2: IUE and ground-based monitoring program. The ranges of optimum times are: line_3: September-November 1994 and January-March 1995. ! question: 9 section: 1 line_1: Not included for Phase II. ! question: 10 section: 1 line_1: Not included for phase II. ! !end of general form text general_form_address: lname: GILLILAND fname: RONALD mi: L category: PI inst: 3470 addr_1: 3700 San Martin Drive city: BALTIMORE state: MD zip: 21218 country: USA phone: 410-338-4454 telex: gillil@stsci.edu ! lname: DUPREE fname: ANDREA mi: K category: CON inst: 2166 addr_1: Smithsonian Astrophys.
