PI: Dr. Fabrice Martins Universite de Montpellier Y CoI: Dr. Jean-Claude Bouret CNRS, Laboratoire d'Astrophysique de N Marseille CoI: Dr. Ana PALACIOS Universite de Montpellier N ------------------------------------------------------------------------------------ Abstract Very massive stars (VMS) are stars with masses in excess of 100 Msun. They are formed in clusters massive enough to populate the initial mass function up to high masses. They are very luminous objects spectroscopically similar to, but much less evolved than, Wolf-Rayet stars. They dominate the integrated ultraviolet spectrum of young clusters. Incorporating them in population synthesis is crucial to interpret spectroscopy of unresolved star forming regions and galaxies such as observed by the CLASSY survey. However very few VMS are directly observable in the Local Universe, especially in the UV: there are about ten such objects located either in 30 Dor in the LMC or in the Galactic cluster NGC 3603. We propose to nearly double the number of VMS UV spectra by targeting the only other place in the Local Universe where VMS can be studied individually in the UV: the two giant HII regions NGC595 and NGC604 in the Triangulum galaxy M33. Our goal is to obtain STIS/G140L spectra of nine (candidate) VMS previously identified in M33. We will determine the stellar and wind properties of VMS at sub-LMC metallicity using atmosphere models. We will determine how their mass loss rate depend on luminosity and Eddington parameter and implement these mass loss rates into new evolutionary models of VMS. Finally, we will develop population synthesis models using new empirical and synthetic spectra of VMS. ------------------------------------------------------------------------------------ Observations Description ------------------------ We plan to obtain long slit STIS spectroscopy of nine candidate very massive stars in the galaxy M33. The stars are located in two giant HII regions: NGC595 and NGC 604. They have V magnitudes between 18.5 and 16.4. We plan to use the G140L filter combined with the MAMA detector to obtain UV spectra of these nine objects. The slit width is 2" (52"x2" in total). Each target can be observed independently, at any time (there is no time constraint). Observations need two orbits (grouped in one visit) for the faintest targets, and a single orbit for the brightest ones. Target acquisition is made either on the science target itself, or on a nearby (distance <2") bright object. ------------------------------------------------------------------------------------ 17085( 3) - 27-Apr-2023 12:34:01 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 DMS-NGC-595- EXT-STAR, WOLF RAYET, RA=01H33M32.7850S +/- 0.14", J2000 V = 18.199 +/- 0.004 U=17.04, B=17.99 5 WOLF RAYET - WN DEC=+30D41'45.98" +/- 0.11" Reference Frame: ICRS Extended: NO Comments: Information retrieved from the SIMBAD database.
