The Variable Detection of Atmospheric Escape around the young, Hot Neptune AU Mic b

Keighley E. Rockcliffe, Elisabeth R. Newton, Allison Youngblood +5

Photoevaporation is a potential explanation for several features within exoplanet demographics. Atmospheric escape observed in young Neptune-sized exoplanets can provide insight in…

A massive hot Jupiter orbiting a metal-rich early-M star discovered in the TESS full frame images

Tianjun Gan, Charles Cadieux, Farbod Jahandar +41

Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these extreme systems remains u…

A Transiting Super-Earth in the Radius Valley and An Outer Planet Candidate Around HD 307842

Xinyan Hua, Sharon Xuesong Wang, Johanna K. Teske +32

We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD 307842 (TOI-784). The planet has a period of 2.8 days, and the radial veloci…

Kepler's Last Planet Discoveries: Two New Planets and One Single-Transit Candidate from K2 Campaign 19

Elyse Incha, Andrew Vanderburg, Tom Jacobs +9

The Kepler space telescope was responsible for the discovery of over 2,700 confirmed exoplanets, more than half of the total number of exoplanets known today. These discoveries too…

Three long period transiting giant planets from TESS

Rafael Brahm, Solène Ulmer-Moll, Melissa J. Hobson +52

We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single transit events in the…

The GAPS Programme at TNG XLII. A characterisation study of the multi-planet system around the 400 Myr-old star HD 63433 (TOI-1726)

M. Damasso, D. Locci, S. Benatti +34

For more than two years, we monitored with the HARPS-N spectrograph the 400 Myr-old star HD\,63433, which hosts two close-in (orbital periods and days) s…

Revising Properties of Planet-Host Binary Systems. III. There is No Observed Radius Gap For Kepler Planets in Binary Star Systems

Kendall Sullivan, Adam L. Kraus, Daniel Huber +7

Binary stars are ubiquitous; the majority of solar-type stars exist in binaries. Exoplanet occurrence rate is suppressed in binaries, but some multiples do still host planets. Bina…
