The results will be related to the line_7: structure of, and physical conditions existing in, the gas streams (and line_8: possibly, the accretion disk) in these systems. line_9: Revision History: Received on RPS 9/1/89; Added to SCCS 9/5/89 line_10: RPSS V7.2 remote & local; Small syntax errs corrected - SALM 9/12/89 line_11: Gyros and other changes - Dolan 9/29/89; Move GX339-4 to cycle2, reduce line_12: repeats to 4 every 0.93D, coarse track - SALM 2/15/90; Condense POL line_13: observations - SALM 2/22/90; Move GX339-4 & A0538-66 to cycle2 - SALM line_14: 3/20/90 ! ! end of abstract general_form_proposers: lname: VAN CITTERS fname: G. mi: W. inst: NATIONAL SCIENCE FOUNDATION country: USA ! lname: BLESS fname: ROBERT mi: C. inst: WISCONSIN, UNIVERSITY OF country: USA ! lname: DOLAN fname: JOSEPH mi: F. inst: NASA, GODDARD SPACE FLIGHT CENTER country: USA ! lname: ELLIOT fname: JAMES mi: L. inst: MASSACHUSETTS INSTITUTE OF TECHNOLOGY country: USA ! lname: ROBINSON fname: EDWARD mi: L. inst: TEXAS, UNIVERSITY OF country: USA ! lname: WHITE fname: RICHARD mi: L. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The photometric and polarimetric light curves of each target will be built up line_2: by measuring the magnitude and linear polarization of the system in several line_3: different wavelength bands at several different phases in one orbit. line_4: Investigation of temporal variations in any gas stream will require line_5: observations over several different orbits. Some of these systems undergo line_6: substantial luminosity changes in the optical or X-ray region of the spectrum; line_7: the observations will be repeated for each different luminosity state the line_8: system assumes. line_10: Cycle 1 (SV/GTO) observations: line_12: Exposures (line numbers) 37 to 48 and lines 55-60 on 1 month centers ! question: 4 section: 1 line_1: UV radiation is believed to originate closer to the accretion disk around the line_2: secondary in X-ray binaries than does longer wavelength optical radiation. line_3: Hence, observations in the UV, accessible only to ST, will probe a different line_4: region of the gas streams between the stars than can be done in the optical. line_5: It is expected that the results will be more directly relatable to the line_6: conditions existing near the neutron star. ! question: 5 section: 1 line_1: The observations must be correlated with the period of the binary to obtain line_2: the desired light curves. ! question: 7 section: 1 line_1: Given scattering from gas streams, the polarimetric (q, u) plot can determine line_2: the location of the stream relative to the line of centers and the orbital line_3: plane and the eccentricity of the scattering location's orbit about the primary line_4: (Dolan and Tapie, Astron. Ap., 139, 249, 1984; Dolan, Astron. Ap., 138, 1, line_5: 1984; and references cited therein). The phases at which photometric and line_6: polarimetric variability occur provide the longitudinal location of the gas line_7: streams; the magnitude of the varitions cn be related to the total amount of line_8: material in the stream. The ionization state of the stream can be determined line_9: from the dependence of the polarimetric variability on wavelength: Rayleigh line_10: scattering varies as the inverse 4th power of the wavelength and indicates line_11: neutral atoms as the scattering agents; Thomson scattering is independent of line_12: wavelength and indicate free electrons (i.e., ionized atoms) as the scattering line_13: agents. Variations in phase of features on the photometric and polarimetric line_14: light curves from orbit to orbit will indicate temporal changes in position of line_15: the scattering region in the gas streams. ! question: 12 section: 1 line_1: The X-ray binaries program is directly related to the first scientific line_2: objective listed in the HSP CEI specifications, "determination of the line_3: properties of ... X-ray binaries, gas streams and accretion disks in compact line_4: binary systems", and to the fifth scientific objective, "determination of the line_5: wavelength and time dependence of polarization in compact binaries". ! question: 13 section: 1 line_1: Photometric and polarimetric light curves of X-ray binaries will be established line_2: at several different UV wavelengths. Changes in these light curves will be line_3: monitored as a function of the luminosity state of the system. The results line_4: will be related to the structure of, and physical conditions in, the gas line_5: streams and accretion disk in these close binaries. ! !end of general form text general_form_address: lname: BLESS fname: R title: DR category: PI ! lname: BLESS fname: ROBERT mi: C. category: PI inst: UNIVERSITY OF WISCONSIN addr_1: SPACE ASTRONOMY LAB. addr_2: 1150 UNIVERSITY AVE. city: MADISON state: WI zip: 53706 country: USA phone: 608-262-1715 ! lname: DOLAN fname: JOSEPH mi: F. category: CON inst: NASA, GODDARD SPACE FLIGHT CENTER addr_1: CODE 681 city: GREENBELT state: MD zip: 20771 country: USA phone: (301)286-5920 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: HDE226868 name_2: CYGXR-1 descr_1: X-RAY BINARY pos_1: RA = 19H 56M 28.8S +/- 0.1S, pos_2: DEC = +35D 03' 55" +/- 1" equinox: 1950 fluxnum_1: 1 fluxval_1: V=8.6 ! targnum: 2 name_1: LMCX-3 descr_1: ^ pos_1: RA = 05H 38M 39.7S +/- 0.1S, pos_2: DEC = -64D 06' 34" +/- 1" equinox: ^ fluxnum_1: 1 fluxval_1: V=16.9 ! targnum: 3 name_1: HD153919 name_2: 4U1700-37 descr_1: ^ pos_1: RA = 17H 00M 32.7S +/- 0.1S, pos_2: DEC = -37D 46' 29" +/- 1" equinox: ^ fluxnum_1: 1 fluxval_1: V=6.5 ! targnum: 4 name_1: HD77581 name_2: VELA-XR-1 descr_1: ^ pos_1: RA = 09H 00M 13.2S +/- 0.1S, pos_2: DEC = -40D 21' 25" +/- 1" equinox: ^ fluxnum_1: 1 fluxval_1: V=6.9 ! targnum: 5 name_1: X-PER name_2: 4U0352+30 descr_1: ^ pos_1: RA = 03H 52M 15.1S +/- 0.1S, pos_2: DEC = +30D 54' 01" +/- 1" equinox: ^ fluxnum_1: 1 fluxval_1: V=6 ! targnum: 6 name_1: A0538-66 descr_1: X-RAY BINARY pos_1: RA = 05H 35M 42.4S +/- 0.1S, pos_2: DEC = -66D 53' 39" +/- 1" equinox: 1950 fluxnum_1: 1 fluxval_1: V=12.8 fluxnum_2: 2 fluxval_2: V=15 ! targnum: 7 name_1: 4U1907+09 descr_1: ^ pos_1: RA = 19H 7M 15.1S +/- 1.5", pos_2: DEC = +09D 44' 53.5" +/- 1.5" equinox: ^ fluxnum_1: 1 fluxval_1: V=16.4 ! targnum: 8 name_1: GX339-4 descr_1: ^ pos_1: RA = 16H 59M 01.9S +/- 0.1S, pos_2: DEC = -48D 43' 06" +/- 1" equinox: ^ fluxnum_1: 1 fluxval_1: V=16 fluxnum_2: 2 fluxval_2: V=18.5 ! targnum: 9 name_1: HD152667 descr_1: ^ pos_1: RA = 16H 53M 06.9S +/- 0.1S, pos_2: DEC = -40D 44' 43.5" +/- 1" equinox: ^ fluxnum_1: 1 fluxval_1: V=6.4 ! targnum: 10 name_1: 4U1820-30 descr_1: X-RAY BINARY pos_1: RA = 18H 20M 27.84S +/- 0.9", pos_2: DEC = -30D 23' 17.0" +/- 0.9" equinox: 1950 ! ! end of fixed targets !
