Abstract In cycle 1 and cycle 4 we obtained the first FOS spectra of individual early type stars in M31, and M33 respectively. Combined with ground based data, these were used to study stellar atmospheres and winds and compare wind velocities, mass loss rates, and abundances with similar galactic stars. We used both the SEI method, and non-LTE model atmospheres to analyse the data, and made direct comparison with spectra and models of galactic stars. Detailed study of hot star population in galaxies outside the Milky Way provides a very important test to theories of stellar winds, star formation and evolution. This work extends the comparison beyond the Magellanic Clouds, to M31 and M33, which are more similar in structure, mass and chemical composition to the Milky Way. The work should sample different environments and galactocentric distances, to check for metallicity gradient, and different spectral types. Our sample to date still has less than 10 stars, mostly O9 to B2 supergiants. Our on-going ground-based program and analysis of the UIT images, provided excellent new targets: earlier O types, a main sequence O, a LBV star and new Wolf Rayet stars. For all the new targets we have complementary blue optical spectra for accurate spectral type determination, and accurate photometry to assure successful target acquisition. ------------------------------------------------------------------------------------ 6038( 11) - 09/28/95 13:23 - [ 2] Observations Description ------------------------ Our target list consists of 7 stars, 5 in M33 and 2 in M31. For two of the stars, we will observe with the FOS/BL, followed by a HRS exposure. During the FOS observations will will obtain parallel observations using the WFPC2. We envision the following sequence of events for each visit: (1) On-board acuqisition using the FOS/BL + mirror through 4.3" aperture; (2) FOS+G270H (5M). Parallel: WFPC2 + F555W 160S (3) FOS+G190H (15M). Parallel: WFPC2 + F439W 10M; (4) FOS+G130H (100M) [2 orbits]. Parallel: WFPC2 + F336W 2 x 15M; WFPC2 + F170W 2 x 15M (5) HRS+G140L (120M). (Visit 1, Visit 7) CURRENTLY THE PARALLELS ARE COMMENTED OUT, AS WE WERE INSTRUCTED. Note that the HRS observations will be via the FOS acquisition as permitted under new rules. Real Time Justification ----------------------- None Calibration Justification ------------------------- None. Additional Comments ------------------- We are specifying a range of ORIENT angles in order for our coordinated parallel WFPC2 exposures to be on scientifically interesting regions. Listed under "visit comments" are alternative ORIENT angles in case our first choices cannot be scheduled. We have, however, verified that the preferred ORIENT angles do occur during observing windows for each target. Also please note that we are using the newly implemented HRS acquisition with the FOS. ------------------------------------------------------------------------------------ Data Distribution Media: 8MM Blocking Factor: 10 Ship To: PI_Address Ship Via: UPS Email: , ------------------------------------------------------------------------------------ 6038( 11) - 09/28/95 13:23 - [ 3] TARGET LIST a) Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 M33-OB88-7 EXT-STAR,Supergiant O RA=1H 34M 59.35S +/- 1", DEC=30D 2000 V=18.51+/-.2 42' 01.1"+/-1",PLATE-ID=00DV U-B=-1.07+/-.3 B-V=-0.03+/-.3 2 M33-OB10-3 EXT-STAR,Supergiant O RA=01H 33M 41.32S+/-1", DEC=30D 2000 V=18.31+/-.2 32' 12.9" +/-1",PLATE-ID=00DV B-V=-0.08+/-0.3 U-B=-1.00+/-0.3 3 M33-AM6 EXT-STAR,Wolf Rayet RA=01H 33M 34.252S+/-1", DEC=30D 2000 V=17.05+/-.2 (WN) 41' 36.91" +/-1",PLATE-ID=00DV B-V=+0.06+/-0.3 U-B=-0.77+/-0.4 4 M33-FUV444 EXT-STAR,Giant O RA=1H 34M 9.918S+/-.07S,DEC=30D 2000 V=17.7+/-0.4 39' 10.58"+/-1",PLATE-ID=00DV B-V=+0.03+/-0.5 U-B=-1.04+/-0.5 5 M33-FUV350 EXT-STAR,Luminous Blue RA=01H 33M 55.953S+/-1",DEC=30D 2000.
