An Isolated Stellar-Mass Black Hole Detected Through Astrometric Microlensing

Kailash C. Sahu, Jay Anderson, Stefano Casertano +90

We report the first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH). We used the Hubble Space Telescope (HST) to carry out precise astrometry…

OGLE-2017-BLG-1186: first application of asteroseismology and Gaussian processes to microlensing

Shun-Sheng Li, Weicheng Zang, Andrzej Udalski +102

We present the analysis of the event OGLE-2017-BLG-1186 from the 2017 Spitzer microlensing campaign. This is a remarkable microlensing event because its source is photometrically b…

One or more bound planets per Milky Way star from microlensing observations

A. Cassan, D. Kubas, J. -P. Beaulieu +39

Most known extrasolar planets (exoplanets) have been discovered using the radial velocity or transit methods. Both are biased towards planets that are relativ…

Limits on additional planetary companions to OGLE-2005-BLG-390L

D. Kubas, A. Cassan, M. Dominik +1

We investigate constraints on additional planets orbiting the distant M-dwarf star OGLE-2005-BLG-390L, around which photometric microlensing data has revealed the existence of the…

Potential Direct Single-Star Mass Measurement

H. Ghosh

We analyze the lightcurve of the microlensing event OGLE-2003-BLG-175/MOA-2003-BLG-45 and show that it has two properties that, when combined with future high resolution astrometry…

OGLE-2003-BLG-238: Microlensing Mass Estimate of an Isolated Star

Guangfei Jiang, D. L. DePoy, A. Gal-Yam +38

Microlensing is the only known direct method to measure the masses of stars that lack visible companions. In terms of microlensing observables, the mass is given by M=(c^2/4G)\tild…
