Constraints on Binarity for the Extreme Oe Variable Star AzV 493
M. S. Oey, Irene Vargas-Salazar, Edmund Hodges-Kluck +6
The extreme Oe star AzV 493 is known to show unusual photometric and spectroscopic variability that suggest the presence of an unseen companion in a highly eccentric and long-perio…
The Close Binary Properties of Massive Stars across Different Environments within the LMC
Maxwell Moe, M. S. Oey, Irene Vargas-Salazar +1
We analyze 4,859 O-stars in the OGLE-III photometric survey of the LMC, including 415 eclipsing binaries (EBs). After accounting for the geometrical probability of eclipses, the pe…
New Field OB and OBe Binaries of the SMC Wing: Observational Properties and Population Modeling
Irene Vargas-Salazar, M. S. Oey, Jan J. Eldridge +9
We present a radial velocity (RV) survey of the field OB and OBe stars of the SMC Wing. We use multi-epoch observations of 55 targets obtained with the Magellan IMACS and M2FS mult…
Strong Variability in AzV 493, an Extreme Oe-Type Star in the SMC
M. S. Oey, N. Castro, M. Renzo +11
We present 18 years of OGLE photometry together with spectra obtained over 12 years, revealing that the early Oe star AzV 493 shows strong photometric (Delta I < 1.2 mag) and spect…
A Search for In-Situ Field OB Star Formation in the Small Magellanic Cloud
Irene Vargas-Salazar, M. S. Oey, Jesse R. Barnes +4
Whether any OB stars form in isolation is a question central to theories of massive star formation. To address this, we search for tiny, sparse clusters around 210 field OB stars f…
