The sensitivity of TESS to transiting planets in TOIs with close-in stellar companions

Colin Littlefield, Kathryn V. Lester, David R. Ciardi +1

High resolution imaging with optical speckle interferometry has revealed that many transiting exoplanet host stars possess close-in stellar companions. The objective of this study…

A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP

Alicia Kendall, Solène Ulmer-Moll, Samuel Gill +53

Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of plan…

A transiting giant planet in orbit around a 0.2-solar-mass host star

Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56

Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…
