Metal-Rich RRc stars in the Carnegie RR Lyrae Survey
Christopher Sneden, George W. Preston, Juna A. Kollmeier +6
We describe and employ a stacking procedure to investigate abundances derived from the low S/N spectra obtained in the Carnegie RR Lyrae Survey (CARRS; Kollmeier et al. 2013). We f…
Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm
G. Terreran, M. L. Pumo, T. -W. Chen +41
We present our study of OGLE-2014-SN-073, one of the brightest Type II SN ever discovered, with an unusually broad lightcurve combined with high ejecta velocities. From our hydrody…
No large population of unbound or wide-orbit Jupiter-mass planets
Przemek Mroz, Andrzej Udalski, Jan Skowron +9
Gravitational microlensing is the only method capable of exploring the entire population of free-floating planets down to Mars-mass objects, because the microlensing signal does no…
Concluding Henrietta Leavitt's Work on Classical Cepheids in the Magellanic System and Other Updates of the OGLE Collection of Variable Stars
I. Soszyński, A. Udalski, M. K. Szymański +9
More than a century ago, Henrietta Leavitt discovered the first Cepheids in the Magellanic Clouds together with the famous period-luminosity relationship revealed by these stars, w…
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…
The OGLE Collection of Variable Stars. Over 450 000 Eclipsing and Ellipsoidal Binary Systems Toward the Galactic Bulge
I. Soszyński, M. Pawlak, P. Pietrukowicz +10
We present a collection of 450 598 eclipsing and ellipsoidal binary systems detected in the OGLE fields toward the Galactic bulge. The collection consists of binary systems of all…
