OGLE-2011-BLG-0462: An Isolated Stellar-mass Black Hole Confirmed Using New HST Astrometry and Updated Photometry

The Astrophysical Journal
The long-duration Galactic-bulge microlensing event OGLE-2011-BLG-0462 produced relativistic astrometric deflections of the source star, which we measured using Hubble Space Telescope (HST) observations taken at eight epochs over ∼6 yr.

Fast Radio Bursts by Stellar Wind Microlensing of a Faint Background Source

The Astrophysical Journal
By assuming the inverse square law of solar wind plasma density as representative of other stars, it is shown that just outside a star, the outward deflection of a passing radio signal at ν  ≈ 1 GHz (which is capable of penetrating the plasma) is about 5
