An Orbit for a Massive Wolf-Rayet Binary in the LMC: An Example of Binary Evolution
Breelyn Cocke, Philip Massey, Nidia I. Morrell +6
Wolf-Rayet (WR) stars are helium-burning, evolved massive stars which have had most of their hydrogen-rich outer layers removed either through stellar winds and/or binary stripping…
Observational Parameters of Blue Large-amplitude Pulsators
P. Pietrukowicz, M. Latour, I. Soszynski +15
Blue large-amplitude pulsators (BLAPs) are a recently discovered class of short-period pulsating variable stars. In this work, we present new information on these stars based on ph…
OGLE-2015-BLG-0845L: A low-mass M dwarf from the microlensing parallax and xallarap effects
Zhecheng Hu, Wei Zhu, Andrew Gould +51
We present the analysis of the microlensing event OGLE-2015-BLG-0845, which was affected by both the microlensing parallax and xallarap effects. The former was detected via the sim…
Measuring the mass function of isolated stellar remnants with gravitational microlensing. II. Analysis of the OGLE-III data
P. Mroz, A. Udalski, L. Wyrzykowski +5
Our knowledge of the birth mass function of neutron stars and black holes is based on observations of binary systems but the binary evolution likely affects the final mass of the c…
OGLE-2016-BLG-1266: A Probable Brown-Dwarf/Planet Binary at the Deuterium Fusion Limit
M. D. Albrow, J. C. Yee, A. Udalski +33
We report the discovery, via the microlensing method, of a new very-low-mass binary system. By combining measurements from Earth and from the Spitzer telescope in Earth-trailing or…
The OGLE Collection of Variable Stars. Classical, Type II, and Anomalous Cepheids toward the Galactic Center
I. Soszyński, A. Udalski, M. K. Szymański +11
We present a collection of classical, type II, and anomalous Cepheids detected in the OGLE fields toward the Galactic center. The sample contains 87 classical Cepheids pulsating in…
