Asteroseismology of Long-Period Variables with OGLE-IV data: Using Global Seismic Parameters as Luminosity Indicators
Qiang Xiong, Tanda Li, Jie Yu +19
Long-period variables (LPVs) are high-luminosity red giants or supergiants with pulsation periods ranging from days to years. Many LPVs in the Large Magellanic Cloud (LMC) and Gala…
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…
OGLE Atlas of Classical Novae. II. Magellanic Clouds
P. Mroz, A. Udalski, R. Poleski +8
The population of classical novae in the Magellanic Clouds was poorly known because of a lack of systematic studies. There were some suggestions that nova rates per unit mass in th…
Interstellar Extinction Curve Variations Toward the Inner Milky Way: A Challenge to Observational Cosmology
David M. Nataf, Oscar A. Gonzalez, Luca Casagrande +18
We investigate interstellar extinction curve variations toward 4 deg of the inner Milky Way in photometry from the OGLE-III and surveys, with supportin…
OGLE Atlas of Classical Novae I. Galactic Bulge Objects
P. Mroz, A. Udalski, R. Poleski +8
Eruptions of classical novae are possible sources of lithium formation and gamma-ray emission. Nova remnants can also become Type Ia supernovae (SNe Ia). The contribution of novae…
OGLE-ing the Magellanic System: Stellar populations in the Magellanic Bridge
D. M. Skowron, A. M. Jacyszyn, A. Udalski +11
We report the discovery of a young stellar bridge, that forms a continuous connection between the Magellanic Clouds. This finding is based on number density maps for stellar popula…
Candidate Gravitational Microlensing Events for Future Direct Lens Imaging
C. B. Henderson, H. Park, T. Sumi +76
The mass of the lenses giving rise to Galactic microlensing events can be constrained by measuring the relative lens-source proper motion and lens flux. The flux of the lens can be…
Gravitational Binary-lens Events with Prominent Effects of Lens Orbital Motion
H. Park, A. Udalski, C. Han +58
Gravitational microlensing events produced by lenses composed of binary masses are important because they provide a major channel to determine physical parameters of lenses. In thi…
Microlensing Discovery of a Population of Very Tight, Very Low-mass Binary Brown Dwarfs
J. -Y. Choi, C. Han, A. Udalski +121
Although many models have been proposed, the physical mechanisms responsible for the formation of low-mass brown dwarfs are poorly understood. The multiplicity properties and minim…
MOA-2010-BLG-523: "Failed Planet" = RS CVn Star
A. Gould, J. C. Yee, I. A. Bond +116
The Galactic bulge source MOA-2010-BLG-523S exhibited short-term deviations from a standard microlensing lightcurve near the peak of an Amax ~ 265 high-magnification microlensing e…
Using Orbital Effects to Break the Close/wide Degeneracy in Binary-lens Microlensing Events
I. -G. Shin, T. Sumi, A. Udalski +37
Microlensing can provide an important tool to study binaries, especially those composed of faint or dark objects. However, accurate analysis of binary-lens light curves is often ha…
Characterizing Lenses and Lensed Stars of High-Magnification Single-lens Gravitational Microlensing Events With Lenses Passing Over Source Stars
J. -Y. Choi, I. -G. Shin, S. -Y. Park +148
We present the analysis of the light curves of 9 high-magnification single-lens gravitational microlensing events with lenses passing over source stars, including OGLE-2004-BLG-254…
OGLE-2005-BLG-018: Characterization of Full Physical and Orbital Parameters of a Gravitational Binary Lens
I. -G. Shin, A. Udalski, C. Han +55
We present the analysis result of a gravitational binary-lensing event OGLE-2005-BLG-018. The light curve of the event is characterized by 2 adjacent strong features and a single w…
Binary microlensing event OGLE-2009-BLG-020 gives a verifiable mass, distance and orbit predictions
J. Skowron, A. Udalski, A. Gould +99
We present the first example of binary microlensing for which the parameter measurements can be verified (or contradicted) by future Doppler observations. This test is made possibl…
