MOA-2020-BLG-208Lb: Cool Sub-Saturn Planet Within Predicted Desert

Greg Olmschenk, David P. Bennett, Ian A. Bond +74

We analyze the MOA-2020-BLG-208 gravitational microlensing event and present the discovery and characterization of a new planet, MOA-2020-BLG-208Lb, with an estimated sub-Saturn ma…

Is there a nearby microlensing stellar remnant hiding in Gaia DR3 astrometry?

Maja Jabłońska, Łukasz Wyrzykowski, Krzysztof A. Rybicki +3

Massive galactic lenses with large Einstein Radii should cause a measurable astrometric microlensing effect, i.e. the light centroid shift due to the motion of the two images. Such…

Photometric and spectroscopic study of the burst-like brightening of two Gaia-alerted young stellar objects

Zsófia Nagy, Péter Ábrahám, Ágnes Kóspál +18

Young stars show variability on different time-scales from hours to decades, with a range of amplitudes. We studied two young stars, which triggered the Gaia Science Alerts system…

SN 2016dsg: A Thermonuclear Explosion Involving A Thick Helium Shell

Yize Dong, Stefano Valenti, Abigail Polin +29

A thermonuclear explosion triggered by a helium-shell detonation on a carbon-oxygen white dwarf core has been predicted to have strong UV line blanketing at early times due to the…

An isolated mass gap black hole or neutron star detected with astrometric microlensing

Casey Y. Lam, Jessica R. Lu, Andrzej Udalski +42

We present the analysis of five black hole candidates identified from gravitational microlensing surveys. Hubble Space Telescope astrometric data and densely sampled lightcurves fr…

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…
