They shape the structures around them and enrich the interstellar medium with metals due to their strong stellar winds. They ionize their environment and transfer momentum from the UV-dominated radiation field to metals. As the progenitors of heavy black holes, evolved massive stars have become a keystone of modern astrophysics. The masses of their black hole remnants predominantly depend on the wind mass loss of envelope-stripped helium (He) stars. The mass loss of these He-burning stars and its metallicity-dependence mark a crucial, yet poorly constrained astrophysical quantity. He stars with a sufficiently high mass loss appear as Wolf-Rayet (WR) stars, detectable even in unresolved stellar populations and distant galaxies due to their strong emission lines. While the general presence of WR stars is known to be correlated with metallicity, recent studies show that current assumptions in stellar evolution and population models are too simplistic. Thus, a proper empirical determination of WR mass loss as a function of mass and metallicity is necessary to understand the true nature and complex metallicity-dependent behaviour of He star mass loss. The diagnostics to determine the metallicity of He stars can only be obtained from UV spectroscopy. We therefore propose COS UV observations of six WR stars in the outskirts of M33, providing a unique opportunity to study very massive evolved He stars at subsolar metallicity. By anchoring mass loss of WR stars in this crucial environment, our observations will deliver one of the most important ingredients needed for realistic stellar evolution and feedback models. ------------------------------------------------------------------------------------ Observations Description ------------------------ We propose to observe six WR stars in the outskirts of M33 with FUV spectroscopy, aiming at a S/N of 20 at 1310 Angstroem. The spectral 16170( 3) - 15-Oct-2020 11:44:42 - [ 2] observations will be performed with the G140L grating with pass band 770 - 1950. This relatively new setting covers the far UV range in one arm, including even strong emission lines below Lyman alpha. Furthermore, this spectral range contains important wind lines, such as the resonance lines of Civ, Nv, and Ovi which act as crucial indicators in order to determine the correct wind parameters and properly constrain the stellar temperature below the expanding layers. Due to the broad lines, the resolution of the G140L grating is sufficient for our spectral analyses with stellar atmospheres, while a S/N of 20 is required to resolve weaker metal lines, detect absorption troughs, and to constrain the iron abundance. All targets combined, we will require 20 orbits to achieve our science goals. The UV provides a unique chance to establish the iron abundance, which is the main driver of massive star winds. While most targets will show only imprints of Fe VI and higher at wavelengths below 1300 Angstroem, the cooler WN8h target (Romano's star) will provide us with a detailed iron forest down to Fe iv, spanning all over the proposed pass band and acting as a crucial benchmark. Our brightest target has a magnitude of mV = 18.7 and an estimated reddening of E(B-V) = 0.05, bringing the object safely below the brightness limit of the COS detector. This was confirmed by ETC calculations with an atmosphere model spectrum. As an additional layer of security, we also cross-checked this with a much hotter, unreddened 200 kK black body input normalized to mV. We will follow the recommended observing strategy and request that the default wavelength-calibration procedure is applied. The observations shall be performed in TIME-TAG mode and use all four FP-POS positions for each target as recommended to enhance the detector's lifetime. ------------------------------------------------------------------------------------ 16170( 3) - 15-Oct-2020 11:44:42 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 7 NM2011-J0132 EXT-STAR, EMISSION LINE RA=01H32M41.3474S +/- 0.0038", J2000 V = 20.75 41.39+303416 STAR, WOLF RAYET, WOLF DEC=+30D34'15.90" +/- 0.00156" .2 RAYET - WN Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
