Detection of 27 candidate circumbinary planets through apsidal precession of eclipsing binaries observed by TESS

Margo Thornton, Benjamin T. Montet, Riley White +2

Most circumbinary planets have been discovered by their transits, limiting our understanding of such systems to those with mutually coplanar architectures. This bias makes it diffi…

Ever Elusive Exospheres: One Probable Detection and Two Non-Detections of Hα Transits in Young Systems

Reilly P. Milburn, Andrew W. Mann, Keighley Rockcliffe +5

Gaps in the exoplanet population, such as the Neptunian Desert, point to the importance of mass-loss in sculpting the radii of close-in exoplanets. Young planets (500Myr) offer…
