A Multiwavelength Study of the Massive Colliding Wind Binary WR 20a: A Possible Progenitor for Fast-Spinning LIGO Binary Black Hole Mergers
Grace M. Olivier, Laura A. Lopez, Katie Auchettl +7
WR 20a is the most massive close-in binary known in our Galaxy. It is composed of two 80 M Wolf-Rayet stars with a short period of 3.7 days in the open cl…
The Red Supergiant Binary Fraction as a Function of Metallicity in M31 and M33
Kathryn F. Neugent
Recent work measuring the binary fraction of evolved red supergiants (RSGs) in the Magellanic Clouds points to a value between 15-30%, with the majority of the companions being un-…
The Red Supergiant Content of M31 and M33
Philip Massey, Kathryn F. Neugent, Emily M. Levesque +2
We identify red supergiants (RSGs) in our spiral neighbors M31 and M33 using near-IR (NIR) photometry complete to a luminosity limit of log L/Lo=4.0. Our archival survey data cover…
Short Term Variability of Evolved Massive Stars with TESS II: A New Class of Cool, Pulsating Supergiants
Trevor Z. Dorn-Wallenstein, Emily M. Levesque, Kathryn F. Neugent +3
Massive stars briefly pass through the yellow supergiant (YSG) phase as they evolve redward across the HR diagram and expand into red supergiants (RSGs). Higher-mass stars pass thr…
The Red Supergiant Binary Fraction of the Large Magellanic Cloud
Kathryn F. Neugent, Emily M. Levesque, Philip Massey +2
The binary fraction of unevolved massive stars is thought to be 70-100% but there are few observational constraints on the binary fraction of the evolved version of a subset of the…
A Survey for C II Emission-Line Stars in the Large Magellanic Cloud
Bruce Margon, Philip Massey, Kathryn F. Neugent +1
We present a narrow-band imaging survey of the Large Magellanic Cloud, designed to isolate the C II 7231, 7236 emission lines in objects as faint as . Th…
