A search for self-lensing binaries with TESS and constraints on their occurrence rate
Natsuko Yamaguchi, Kareem El-Badry, Nicholas M. Sorabella
Five self-lensing binaries (SLBs) have been discovered with Kepler light curves. They contain white dwarfs (WDs) in AU-scale orbits that gravitationally lens solar-type companions.…

The First TESS Self-Lensing Pulses: Revisiting KIC 12254688
Nicholas M. Sorabella, Silas G. T. Laycock, Dimitris M. Christodoulou +1
We report the observations of two self-lensing pulses from KIC 12254688 in Transiting Exoplanet Survey Satellite (TESS) light curves. This system, containing a F2V star and white-d…

Self-Lensing in Eclipsing X-ray Binary Systems
Nicholas M. Sorabella, Silas G. T. Laycock
This project examines the feasibility of using gravitational lensing to measure the mass of compact objects in eclipsing X-ray binary (XRB) systems. We investigate which kind of XR…
