IUE data have tentatively shown redshifted emission at ~700 km/s. line_3: The GHRS observations will be used to a) confirm the redshift, and b) to line_4: obtain details of the accreting gas which are not visible at the signal-to line_5: noise and resolution of the IUE spectra. ! ! end of abstract general_form_proposers: lname: MCCLUSKEY JR. fname: GEORGE mi: E. inst: LEHIGH UNIVERSITY country: USA ! lname: KONDO fname: YOJI inst: NASA, GODDARD SPACE FLIGHT CENTER country: USA ! lname: BRUHWEILER fname: FRED mi: C. inst: CATHOLIC UNIVERSITY OF AMERICA country: USA ! lname: BOGGESS fname: ALBERT inst: NASA, GODDARD SPACE FLIGHT CENTER country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The observations of V Sge will be made on two visits, separated by at least line_2: 30 days. During the first visit we will observe the N V, SI IV, C IV, He II line_3: and Mg II emission lines. The second visit, which will consist of an line_4: observation at C IV only will be used to search for phase-dependent line_5: changes in the redshift of the C IV emission. ! question: 3 section: 2 line_1: COMMENT CONTINUED FROM EL PAGE 20, LINE 69.000: The rest of this comment is line_2: "if at all practical". line_4: COMMENT CONTINUED FROM EL PAGE 21, LINE 75.000: The rest of this comment is line_5: "if at all practical". ! question: 4 section: 1 line_1: Data needed for this investigation are high-resolution ultraviolet spectra that line_2: cannot be obtained from ground or with the IUE> ! question: 7 section: 1 line_1: All data reduction and analysis are expected to be performed at NASA/GSFC or, line_2: in part, at Space Telescope Science Institute. ! question: 10 section: 1 line_1: Necessary resources will be supplied by the host institution, partially line_2: supported by the NASA funds provided through the HRS PI. ! question: 13 section: 1 line_1: Ten interacting binaries have been selected to study the manner of mass flow. line_2: Based on available data, these binaries are quite possibly in or near the line_3: rarely observed, shourt-lived phase of super critical mass transfer. Currently, line_4: only beta Lyrae is stroungly presumed to be in that elusive state. ! !end of general form text general_form_address: lname: BOGGESS fname: ALBERT title: DR. category: PI inst: NASA, GODDARD SPACE FLIGHT CENTER addr_1: CODE 600 city: GREENBELT state: MD zip: 20771 country: USA ! lname: KONDO fname: YOJI inst: NASA, GODDARD SPACE FLIGHT CENTER addr_1: CODE 684 city: GREENBELT state: MD zip: 20771 country: USA phone: (301)286-6247 ! lname: MCCLUSKEY JR. fname: GEORGE mi: E. inst: LEHIGH UNIVERSITY addr_1: DIVISION OF ASTRONOMY city: BETHLEHEM state: PA zip: 18018 country: USA phone: (215)861-3721 ! lname: BRUHWEILER fname: FRED mi: C. inst: CATHOLIC UNIVERSITY OF AMERICA addr_1: DEPT.
