We report the discovery of TOI-2180 b, a 2.8 giant planet orbiting a slightly evolved G5 host star. This planet transited only once in Cycle 2 of the primary Transiting…
Mysterious Dust-emitting Object Orbiting TIC 400799224
Brian P. Powell, Veselin Kostov, Saul Rappaport +24
We report the discovery of a unique object of uncertain nature -- but quite possibly a disintegrating asteroid or minor planet -- orbiting one star of the widely separated binary T…
A Second Planet Transiting LTT 1445A and a Determination of the Masses of Both Worlds
