False-positive Self-lensing Events: TESS Observing Asteroid-crossing Events in Disguise

We report observations of four asteroid-crossing events in Transiting Exoplanet Survey Satellite light curves masquerading as self-lensing pulses from binary systems containing main-sequence stars and black hole or neutron-star companions. The observed changes in flux and the durations of the events...
