It seeks to detect line_3: and identify the important physical processes involved in line_4: the initation of a wind and in the accelerated flow -- line_5: e.g. the relation between processes operating in line_6: the photosphere (e.g. non-radial pulsations, micro- line_7: turbulence, etc.) and the properties of the wind. ! question: 4 section: 1 line_1: The ST/GHRS is necessary to obtain profiles of wind lines line_2: at high S/N and high time resolution. ! question: 5 section: 1 line_1: The monitoring of HD 24912 should be scheduled in the line_2: same week that Lambda Cep is being observed, so as to line_3: coordinate ground-based supporting observations. It was line_4: requested to observe Lam Cep in Sep or Oct. 1992 (as part line_5: of 1211P augmentation). ! question: 13 section: 1 line_1: I propose to use the unprecedented high-dispersion, high line_2: S/N, and high time-resolution of the ST/HRS to explore line_3: the winds of early-type stars. ! !end of general form text general_form_address: lname: HEAP fname: SARA mi: R. category: PI inst: GODDARD SPACE FLIGHT CENTER addr_1: CODE 681 city: GREENBELT state: MD zip: 20771 country: USA ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: HD24912 name_2: XI-PER descr_1: A, 104, 905 pos_1: RA=3H 58M 57.8S+/-0.2", pos_2: DEC=+35 D47' 28.0"+/-0.2" equinox: 2000 pm_or_par: NO pos_epoch_bj: B pos_epoch_yr: 2000.00 ra_pm_val: 0.000267 ra_pm_unct: 0.000267 dec_pm_val: 0.0010 dec_pm_unct: 0.0030 comment_1: BRIGHT O STAR WITH DAC'S IN WIND comment_2: POSITION FROM YALE BS 4.0 CATALOG fluxnum_1: 1 fluxval_1: V=4.04+/-0.1,B-V=+0.01,U-B=-0.92 ! ! end of fixed targets !
