It seeks to detect line_3: and identify the important physical processes involved in line_4: the initiation of a wind and in the accelerated flow. line_5: In particular, it seeks to determine whether there is line_6: observational evidence between processes operating in line_7: the photosphere (e.g. non-radial pulsations, micro- line_8: turbulence, etc.) and the properties of the wind, including line_9: the possible presence of low-velocity DAC's. ! 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 210839 should be scheduled at a time line_2: when the star is at its closest to the continuous viewing line_3: zone (CVZ). Also, for simultaneous ground-based and IUE line_4: observations, the Sep. - Oct. 1992 is best. ! 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: HD210839 name_2: LAMBDA-CEP descr_1: A, 107, 905 pos_1: RA=22H11M30.62S+/-0.2", pos_2: DEC=+59D24'51.0"+/-0.2", pos_3: PLATE-ID=02X2 equinox: 2000 pm_or_par: NO pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: 0.000067 ra_pm_unct: 0.000267 dec_pm_val: -0.0060 dec_pm_unct: 0.0030 an_prlx_val: 0.0060 an_prlx_unct: 0.0030 comment_1: BRIGHT OF STAR WITH DAC'S IN WIND fluxnum_1: 1 fluxval_1: V=5.25+/-0.1 fluxnum_2: 2 fluxval_2: F(1300)=1.26E-10 ! ! end of fixed targets !
