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…
New Short-Period Delta Scuti Stars in OGLE-IV Fields toward the Galactic Bulge
P. Pietrukowicz, M. Ratajczak, I. Soszynski +12
We report the classification of 24 puzzling short-period variable stars located in OGLE-IV Galactic bulge fields. The stars are low-amplitude (<0.05 mag) multi-periodic objects wit…
The OGLE Collection of Variable Stars. Nearly 66,000 Mira stars in the Milky Way
Patryk Iwanek, Igor Soszyński, Szymon Kozłowski +12
We present a collection of 65,981 Mira-type variable stars found in the Optical Gravitational Lensing Experiment (OGLE) project database. Two-thirds of our sample (40,356 objects)…
Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +68
We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current lite…
A search for strong magnetic fields in massive and very massive stars in the Magellanic Clouds
S. Bagnulo, G. A. Wade, Y. Naze +13
Despite their rarity, massive stars dominate the ecology of galaxies via their strong, radiatively-driven winds throughout their lives and as supernovae in their deaths. However, t…
Blue large-amplitude pulsators as a new class of variable stars
P. Pietrukowicz, W. A. Dziembowski, M. Latour +13
Regular intrinsic brightness variations observed in many stars are caused by pulsations. These pulsations provide information on the global and structural parameters of the star. T…
