Non-evolutionary effects on period change in Magellanic Cepheids II. Empirical constraints on non-linear period changes
Rajeev Singh Rathour, RadosÅaw Smolec, Gergely Hajdu +5
Classical Cepheids are not only excellent standard candles, but also invaluable tools to test stellar evolution and pulsation theories. Rates of their pulsation period change, quan…

Examining the brightness variability, accretion disk, and evolutionary stage of the binary OGLE-LMC-ECL-14413
R. E. Mennickent, G. DjuraÅ¡eviÄ, J. A. Rosales +6
Our study aims to elucidate both short-term and long-term variations in the light curve of the eclipsing system OGLE-LMC-ECL-14413, with a particular focus on the unusual reversals…

Limits on planetary-mass primordial black holes from the OGLE high-cadence survey of the Magellanic Clouds
Przemek Mróz, Andrzej Udalski, MichaÅ K. SzymaÅski +11
Observations of the Galactic bulge revealed an excess of short-timescale gravitational microlensing events that are generally attributed to a large population of free-floating or w…
