OGLE-2015-BLG-1609Lb: Sub-jovian planet orbiting a low-mass stellar or brown dwarf host
M. J. Mróz, R. Poleski, A. Udalski +70
We present a comprehensive analysis of a planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA. Each of these s…
The OGLE Collection of Variable Stars: Over 18 000 Rotating Variables toward the Galactic Bulge
P. Iwanek, I. Soszyński, K. Stępień +14
Stellar rotation, a key factor influencing stellar structure and evolution, also drives magnetic activity, which is manifested as spots or flares on stellar surface. Here, we prese…
The Milky Way as Seen by Classical Cepheids II: Spiral Structure
Ronald Drimmel, Shourya Khanna, Eloisa Poggio +1
As a relatively young and bright population and the archetype of standard candles, classical Cepheids are an ideal population on which to trace the non-axisymmetric structure in th…
The Milky Way as Seen by Classical Cepheids I: Distances Based on Mid-infrared Photometry
Dorota M. Skowron, Ronald Drimmel, Shourya Khanna +3
Classical Cepheids are the archetype of the standard candle, thanks to the period-luminosity relation which allows to measure their intrinsic brightness. They are also relatively y…
Blue Large-Amplitude Pulsators and Other Short-Period Variable Stars in OGLE-IV Fields of the Outer Galactic Bulge
J. Borowicz, P. Pietrukowicz, J. Skowron +13
In this work, we search the OGLE-IV outer Galactic bulge fields for short-period variable objects. The investigation focuses on unexplored timescales roughly below one hour in an a…
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…
