This proposal line_3: addresses the unsolved problems of non-radiative heating and wind line_4: acceleration in cool star atmospheres. We propose to obtain spectra of line_5: (a) optically thin emission lines sensitive both to electron density line_6: and to mass motions, (b) Fe II lines strategically selected to sample line_7: wide ranges of optical depth and excitation temperature within the line_8: chromosphere and wind, (c) the chromospheric "continuum" and CO line_9: absorption systems which will help to constrain physical conditions in line_10: cooler atmospheric components and (d) the Mg II and O I resonance line_11: lines to study the wind and interstellar absorption profiles. The best line_12: available IUE data, in conjunction with radiative transfer line_13: calculations, have provided clues to the atmospheric characteristics. line_14: The GHRS is needed to obtain the high quality data necessary for us to line_15: construct a realistic, semi-empirical, spherically symmetric model line_16: atmosphere. A major aim is to compare the atmospheric and wind line_17: structure derived for lambda Vel with that determined from HST eclipse line_18: spectra of the zeta Aur binary system, whose primary has very similar line_19: physical parameters to lambda Vel. Until now, the binary systems have line_20: provided the only reliable method of determining wind acceleration pro* ! ! end of abstract general_form_proposers: lname: ROBINSON fname: RICHARD mi: D inst: 1780 country: USA ! lname: CARPENTER fname: KENNETH mi: G inst: 2866 country: USA ! lname: JUDGE fname: PHIL mi: G inst: 2892 country: USA ! lname: HARPER fname: GRAHAM inst: 1764 country: USA ! lname: WAHLGREN fname: GLENN mi: M inst: 1780 country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The program used the GHRS to observe the star lambda Vel.

Long duration, high resolution IUE exposures of this line_3: object have been taken by several observers. These data provide line_4: valuable information about the general character of the star and will line_5: be used during the analysis of the HST data. However, they lack the line_6: quality to allow investigation of either the turbulence or the flows in line_7: the atmosphere. SV and GTO observations clearly demonstrate the line_8: increased sensitivity, wavelength resolution, dynamic range and S/N line_9: characteristics of the GHRS over that obtainable with the IUE line_10: (Carpenter et al. 1991, Ap.J. (letters), 377, L45.). Overall, the line_11: GHRS is the only current instrument capable of providing us with the line_12: very high precision line profiles, fluxes, and absolute velocities line_13: required for our program. ! question: 5 section: 1 line_1: NONE ! question: 6 section: 1 line_1: We require the highest possible wavelength accuracy in order to measure line_2: absolute flow velocities in the chromosphere, wind and circumstellar line_3: shell of our target star (down to the 1 km/sec level in the medium and line_4: echelle observations) as well as aiding in the identification of the line_5: many weak features we expect in the low resolution data. Experience line_6: with SV and SAO data (Carpenter et al. 1991, HST Workshop) has line_7: demonstrated that the default calibration will produce uncertainties of line_8: up to 3 diodes due to magnetic and thermal drifts within the line_9: spectrograph. Using internal Pt lamp spectra taken during the SPYBAL line_10: procedures we can estimate the amount of drift and can therefore line_11: reduce the degree of uncertainty to about 0.5 diodes. To obtain the line_12: greatest possible wavelength accuracy we require dedicated WAVECAL line_13: exposures using the internal Pt lamps to be connected to each GHRS line_14: science exposure. Experience has shown that with care calibrations line_15: good to 0.1 diode can be obtained using these exposures. For best line_16: results the wavelength calibrations must be taken at the same line_17: carrousel position and close in time to the science exposures to line_18: remove uncertainties caused by the geomagnetic (GIMP) and thermal line_19: drifts which move the image around on the GHRS photocathode. Long line_20: exposures must also broken into time sequences of 5 minute line_21: integrations so that the drifts can be identified and corrected. ! ! question: 8 section: 1 line_1: NONE ! question: 9 section: 1 line_1: GTO 1195: Outer Atmospheres of Cool Luminous Stars - Cycle 0 (Alpha Ori) line_2: 3212: Outer Atmospheres of Cool Luminous Stars - Cycle 1 (Gamma Cru) line_4: GTO 1198: Physical Conditions and Velocity Structures in the Red Giant line_5: 3934: Winds in the Binaries CI Cyg and EG And - Cycle 2 (2 targets) line_7: GTO 1199: Alpha Ori Team Project - Cycle 1 line_9: These proposals represent the GTO science program, as adjusted for line_10: spherical abberation, of GHRS IDT Co-I K. Carpenter. Programs 1195, line_11: 3212, and 1199 are related to this proposal. Proposals 1198 & 3934 line_12: are studies of symbiotic stars and not directly related to the current line_13: proposal. SAO program 3023 (Alpha Tau) observations have been used to line_14: assess the feasibility of programs such as these which involve line_15: observations of narrow emission-line sources (see the Ap.J. reference line_16: below). ! question: 10 section: 1 line_1: CSC personnel have access to VAX mainframe computers and peripherals at line_2: several sites for basic data reduction and analysis. Data analysis line_3: software, including STSDAS and spectral analysis packages based on the line_4: Interactive Data Language (IDL) are also available. There are a large line_5: number of astronomers at CSC available for expert advice to an line_6: investigator on observational techniques, detector calibration, data line_7: analysis, and theoretical modeling. CSC also provides a pool of line_8: research assistants and data technicians as well as administrative and line_9: secretarial support for research programs. ! !end of general form text general_form_address: lname: ROBINSON fname: RICHARD mi: D category: PI inst: 1780 addr_1: CODE 681/CSC addr_2: GODDARD SPACE FLIGHT CENTER city: GREENBELT state: MD zip: 20771 country: USA phone: (301) 286-4530 telex: HRS::HRSROBINSON ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: HD78647 name_2: LAMBDA-VEL descr_1: A, descr_2: 140 pos_1: RA = 09H 07M 59.776S +/- 0.01S, pos_2: DEC = -43D 25' 57.38" +/- 0.1" equinox: 2000 pos_epoch_bj: J pos_epoch_yr: 2000.00 ra_pm_val: -0.001000 dec_pm_val: 0.0130 an_prlx_val: 0.0220 rv_or_z: V=+18.0 fluxnum_1: 1 fluxval_1: V=2.21+/-0.1, TYPE=K5IB fluxnum_2: 2 fluxval_2: B-V=1.66 fluxnum_3: 3 fluxval_3: F-LINE(1300)=5+/-3 E-13 fluxnum_4: 4 fluxval_4: F-CONT(2000)=10+/-5 E-15 fluxnum_5: 5 fluxval_5: F-CONT(2300)=10+/-3 E-14 fluxnum_6: 6 fluxval_6: F-CONT(2700)=10+/-3 E-13 fluxnum_7: 7 fluxval_7: F-CONT(2800)=10+/-2 E-13 fluxnum_8: 8 fluxval_8: F-LINE(2800)=50+/-10 E-12 ! ! end of fixed targets !
