A Survey Length for AGN Variability Studies
Szymon Kozłowski
The damped random walk (DRW) process is one of the most commonly used and simplest stochastic models to describe variability of active galactic nuclei (AGN). An AGN light curve can…
OGLE-2019-BLG-0304: Competing Interpretations between a Planet-binary Model and a Binary-source + Binary-lens model
Cheongho Han, Andrzej Udalski, Chung-Uk Lee +31
We analyze the microlensing event OGLE-2019-BLG-0304, whose light curve exhibits two distinctive features: a deviation in the peak region and a second bump appearing ~days…
OGLE-2018-BLG-1185b : A Low-Mass Microlensing Planet Orbiting a Low-Mass Dwarf
Iona Kondo, Jennifer C. Yee, David P. Bennett +94
We report the analysis of planetary microlensing event OGLE-2018-BLG-1185, which was observed by a large number of ground-based telescopes and by the Space Telescope. The…
Binarity as the Origin of Long Secondary Periods in Red Giant Stars
I. Soszyński, A. Olechowska, M. Ratajczak +13
Long secondary periods (LSPs), observed in a third of pulsating red giant stars, are the only unexplained type of large-amplitude stellar variability known at this time. Here we sh…
Three microlensing planets with no caustic-crossing features
Cheongho Han, Andrzej Udalski, Doeon Kim +31
We search for microlensing planets with signals exhibiting no caustic-crossing features, considering the possibility that such signals may be missed due to their weak and featurele…
KMT-2019-BLG-1715: planetary microlensing event with three lens masses and two source stars
Cheongho Han, Andrzej Udalski, Doeone Kim +61
We investigate the gravitational microlensing event KMT-2019-BLG-1715, of which light curve shows two short-term anomalies from a caustic-crossing binary-lensing light curve: one w…
