High resolution line_4: profiles of P Cygni-type lines formed in the wind of the K4Ib supergiant line_5: projected against the B8 star will be analyzed to determine the velocity law, line_6: mass low rate, and ionization state of the wind. Observations will be at a line_7: number of phases during the ingress or egress, but all should be either during line_8: ingress or during egress. ! ! end of abstract general_form_proposers: lname: WEYMANN fname: RAY mi: J. inst: ARIZONA, UNIVERSITY OF country: USA ! lname: LINSKY fname: JEFFREY mi: L. inst: COLORADO, UNIVERSITY OF country: USA ! lname: HEAP fname: SARA mi: R. inst: NASA, GODDARD SPACE FLIGHT CENTER country: USA ! lname: REIMERS fname: DIETER inst: HAMBURGER STERNWARTE country: GERMANY, WEST esa: Y ! lname: BRANDT fname: JOHN mi: C. inst: NASA, GODDARD SPACE FLIGHT CENTER country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: We intend to observe Zeta Aurigae with the HRS at 8 different phases: 4 line_2: times during the chromospheric phases (+21d to + 30d), 3 times during the wind line_3: acceleration phase (+30d + 60d), and once during the wind phase (beyond +60d). line_4: All observations should be either during ingress (if HST is launched on time) line_5: or egress. Ingress times are preferred and are indicated on Exposure Log. The line_6: alternative egress times are indicated in parenthesis. The appropriate cycles line_7: are dictated by the launch date and time critical observations. ! question: 4 section: 1 line_1: The best available lines are in the ultraviolet. Observations of the line_2: 2983-3088 A lines are not feasible from the ground. Even from Mauna Kea they line_3: would be in excess of 50 hours. ! question: 5 section: 1 line_1: This is an eclipsing binary system so that observations at specific phases line_2: are essential. ! question: 7 section: 1 line_1: Dieter Reimers and his collaborators at Hamburger Sternwarte have written line_2: a three dimentional radiative transfer code to describe line formation in line_3: multilevel atoms in the extended geometries appropriate to these systems. ! question: 10 section: 1 line_1: Postdoctoral research associates to be supported by GTO budget. ! question: 12 section: 1 line_1: The total observing time includes overhead of 420 seconds for each use of line_2: WACC1+WACC2 sequence, 285 seconds for each use of CHROM sequence, and 420 line_3: seconds for each use of WIND1+WIND2 sequence. ! question: 13 section: 1 line_1: The goal of this program is to study the wind acceleration process in K line_2: supergiants by observing the eclipsing Zeta Aurigae system at a number of line_3: phases during its eclipse centered on 4 August 1990. High resolution line_4: profiles of P Cygni-type lines formed in the wind of the K41b supergiant line_5: projected against the B8 star will be analyzed to determine the velocity law, line_6: mass loss rate, and ionization state of the wind. Observations will be at a line_7: number of phases during ingress or egress, but all should be either during line_8: ingress or during egress. ! !end of general form text general_form_address: lname: LINSKY fname: JEFFREY mi: L. category: PI inst: JILA, UNIVERSITY OF COLORADO addr_1: CAMPUS BOX 440 city: BOULDER state: CO zip: 80309 country: USA phone: (303) 492-7838 telex: 755842JILA ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: HD32068 name_2: ZETA-AUR descr_1: K4IB+B8 BINARY SYSTEM pos_1: RA = 05H 02M 28.6S +/-.1S, pos_2: DEC = +41D 04' 33" +/-1" equinox: 2000 pm_or_par: NO pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: 0.000600 ra_pm_unct: 0.000067 dec_pm_val: -0.0220 dec_pm_unct: 0.0010 an_prlx_val: 0.0050 rv_or_z: V = +13 fluxnum_1: 1 fluxval_1: V = 3.75 ! ! end of fixed targets !
