In LMC X-4, line_3: these will be carried out at two precessional phases as well. The data will be line_4: used to study stellar wind ionisation and velocity changes with X-ray binary line_5: phase, and with variable accretion disk obscuration of X-rays. WFC images with line_6: UV grating and UV filter in parallel to study LMC hot star population. ! ! end of abstract general_form_proposers: lname: HUTCHINGS fname: JOHN mi: B. inst: DOMINION ASTROPHYSICAL OBSERVATORY country: CANADA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: For LMC X-4, HRS low dispersion spectra will be taken at binary phases 0.3, line_2: 0.8, twice, at precession phases with maximum and minimum X-ray shielding of line_3: the primary. line_8: LMC X-1 will be observed at two binary phases with HRS at low dispersion. ! question: 4 section: 1 line_1: Only ST and HRS FOS can provide the S/N and spectral resolution for this study. ! question: 5 section: 1 line_1: Orbit and precession phasing is essential to the investigation. ! question: 7 section: 1 line_1: All data will be analyzed at DAO using spectroscopic software. Ongoing line_2: ground-based spectroscopy will update binary and precession ephemeris and line_3: monitor spectrum near to time of observation. ! question: 10 section: 1 line_1: All support by DAO. ! question: 13 section: 1 line_1: HRS spectra will be obtained at low resolution of LMC X-4, LMC X-1 at binary line_2: phases 0.3, 0.8 and repeated at LMC X-4 precession phases at maximum and line_3: minimum X-ray illumination of the primary. line_4: Data will be used line_5: to study mass flow, disk geometry, and heating effects of X-rays. ! !end of general form text general_form_address: lname: HUTCHINGS fname: JOHN mi: B. title: PROF. category: PI inst: DOMINION ASTROPHYSICAL OBSERVATORY addr_1: 5071 W.
