Detection of new Galactic Wolf-Rayet stars with SPHEREx
Paul A. Crowther, Erin L. Smith
We assess the potential for the NASA Explorer SPHEREx mission in adding to the Milky Way census of Wolf-Rayet (WR) stars by extracting 0.75--5micron spectrophotometry of 30 candida…
Isolated massive star candidates in NGC 4242 with GULP
Pietro Facchini, Eva K. Grebel, Anna Pasquali +16
There is considerable debate on how massive stars form, including whether a high-mass star must always form with a population of low-mass stars or whether it ca…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
The UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Large Director's Discretionary Program with Hubble. I. Goals, Design, and Initial Results
Julia Roman-Duval, William J. Fischer, Alexander W. Fullerton +44
Specifically selected to leverage the unique ultraviolet capabilities of the Hubble Space Telescope, the Hubble Ultraviolet Legacy Library of Young Stars as Essential Standards (UL…
Weighing Melnick 34: the most massive binary system known
Katie A. Tehrani, Paul A. Crowther, Joachim M. Bestenlehner +4
Here we confirm Melnick 34, an X-ray bright star in the 30 Doradus region of the Large Magellanic Cloud, as an SB2 binary comprising WN5h+WN5h components. We present orbital soluti…
The Very Massive Star Content of the Nuclear Star Clusters in NGC 5253
L. J. Smith, P. A. Crowther, D. Calzetti +1
The blue compact dwarf galaxy NGC 5253 hosts a very young starburst containing twin nuclear star clusters, separated by a projected distance of 5 pc. One cluster (#5) coincides wit…
Very Massive Stars in the Local Universe
Jorick S. Vink
Recent studies suggest the existence of very massive stars (VMS) up to 300 solar masses in the local Universe. As this finding may represent a paradigm shift for the canonical stel…
Very Massive Stars (VMS) in the Local Universe
Jorick S. Vink, Alexander Heger, Mark R. Krumholz +25
Recent studies have claimed the existence of very massive stars (VMS) up to 300 solar masses in the local Universe. As this finding may represent a paradigm shift for the canonical…
Interstellar Ti II in the Milky Way and Magellanic Clouds
Daniel E. Welty, Paul A. Crowther
We discuss several sets of Ti II absorption-line data, which probe a variety of interstellar environments in our Galaxy and in the Magellanic Clouds. Comparisons of high-resolution…
Mid-Infrared diagnostics of metal-rich HII regions from VLT and Spitzer Spectroscopy of Young Massive Stars in W31
JP Furness, PA Crowther, PW Morris +4
We present near-IR VLT/ISAAC and mid-IR Spitzer/IRS spectroscopy of the young massive cluster in the W31 star-forming region. H-band spectroscopy provides refined classifications f…
A FEROS spectroscopic study of the extreme O supergiant He 3-759
P. A. Crowther, C. J. Evans
We present a study of the extreme O-type supergiant He 3-759 using new high-resolution FEROS data, revealing that it is a near spectroscopic twin of HD 151804 (O8 Iaf). We investig…
