Every 195 days the A1 dwarf secondary passes behind the line_3: outer atmosphere of the G6 II primary and can be used as light source to line_4: observe absorption lines from plasma in the G star atmopshere. The G line_5: star has a hybrid-chromosphere structure with hot transition region line_6: plasma and a cool stellar wind. THESE OBSERVATIONS WOULD BE THE FIRST line_7: ECLIPSE OBSRRVATIONS OF THIS TYPE OF ATMOSPHERE WITH GHRS AND COMPARED line_8: WITH OUR RESULTS FOR THE K4 SUPERGIANT Zeta Aur, which shows only the line_9: typical red supergiant wind. We shall model the observed line profiles line_10: and determine the temperature structure, density stratification, wind line_11: acceleration/turbulence/ionization as a function of distance above the line_12: G star photosphere. The hot and cool plasma are intermixed in this line_13: outer atmosphere and we will quantify this "thermal bifurcation". Both line_14: the static and outflowing components of the atmopshere will be modelled. line_15: The mass loss rate and the wind velocity and density laws as a function line_16: of radius will be determined. The vast majority of the needed modelling line_17: code will have been developed already for our Zeta Aur analysis. This line_18: project represents an opportunity to significantly advance line_19: knowledge about the spatial structuring of cool star outer atmospheres line_20: and the physical process operating within them. ! ! end of abstract general_form_proposers: lname: BROWN fname: ALEXANDER title: PI inst: 1764 country: USA ! lname: LINSKY fname: JEFFREY mi: L. inst: 1764 country: USA ! lname: BENNETT fname: PHILIP inst: 1764 country: USA ! lname: HARPER fname: GRAHAM inst: 1764 country: USA ! lname: BAADE fname: ROBERT inst: 5580 country: GERMANY esa: Y ! lname: KIRSCH fname: THOMAS inst: 5580 country: GERMANY esa: Y ! lname: REIMERS fname: DIETER inst: 5580 country: GERMANY esa: Y ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Our proposed observations will provide the first high-quality (S/N = 60- line_2: 80) UV spectrum of HR2554 during atmospheric and photospheric eclipse. line_3: Requested exposures are listed below. The exposure times at short line_4: wavelengths during partial eclipse are increased by 50% to compensate line_5: somewhat for the decrease continuum signal. The quoted signal-to-noise line_6: values are calculated per resolution element (i.e. per two diodes on the line_7: detector). The large dynamic range and low noise of the GHRS ensures line_8: that many weak features can be accurately measured in these exposures. line_9: The observations requested in Phase 1 were: ! question: 3 section: 2 line_1: The observations requested in Phase 1 were: line_2: ---------------------------------------------------------------------- line_3: Ion UV Lambda Grating Continuum Cts/ S/N Exp. line_4: mult.

IUE has been used extensively to study this line_4: target and further observational advances depend on the acquisition of line_5: higher S/N spectra with GHRS.

Lett., 377, L45.) line_8: will allow more accurate and detailed modelling of the circumstellar line_9: environment around the G6 hybrid-atmosphere bright giant primary of line_10: HR2554. ONLY THE GHRS IS CAPABLE OF PROVIDING THE VERY HIGH PRECISION line_11: LINE PROFILES, FLUXES, AND ABSOLUTE VELOCITIES NEEDED FOR OUR MODELLING. ! question: 5 section: 1 line_1: The observations must be scheduled at specific phases during the eclipse line_2: of the A1 dwarf secondary by the extended atmosphere of the bright giant line_3: primary. Eclipses of HR2554 occur every 195 days and during Cycle 4 line_4: eclipses are centered on 1994 April 18 and 1994 October 30. The system line_5: lies near the ecliptic pole so the beta angle (star-antiSun angle) is line_6: always close to 90 degrees. Therefore, the star is observable by HST at line_7: all dates during Cycle 4. Coordinated IUE observations will be possible line_8: if the April eclipse is observed. line_9: Times of mideclipse are given by t = JD2447898.57 + n*195.28days. line_10: Observations are requested 1 month before mid-eclipse, and at -4.5,-3.0, line_11: -1.7,-0.8,+0.8,+1.7,+3.0,+4.5 days relative to mid-eclipse. The time line_12: between first and fourth contacts is 3.2 days. (See Schroder 1990, line_13: A&A, 236,165 for details). line_14: Eclipses during Cycle 4 occur on 1994 April 18.31 and October 30.59. line_15: The Exposure Logsheet is constructed specifically for the April 1994, line_16: if the October eclipse is actually observed a new version of the Phase 2 line_17: form will be provided. ! question: 6 section: 1 line_1: We require high wavelength accuracy in order to measure absolute line_2: velocities in the chromosphere and wind of our target star. We therefore line_3: request one WAVECAL exposure for ECH-B and G160M at each epoch. line_4: Wavelength matching between different spectra at each epoch and between line_5: epochs will be done using interstellar features. Routine SPYBAL spectra line_6: will be used to calibrate spectra without dedicated WAVCALS. The WAVCAL line_7: exposures must be taken at the same carrousel position and close in time line_8: to the science exposures to remove uncertainties caused by GIMP and line_9: thermal drifts which move the image around on the GHRS photocathode. ! ! ! question: 8 section: 1 line_1: None. ! question: 9 section: 1 line_1: GO Program 3626 - Empirical determination of the wind velocity and line_2: density laws for the K supergiant Zeta Aurigae from eclipse ingress line_3: Spectra (A.
