A transiting rocky super-Earth and a non-transiting sub-Neptune orbiting the M dwarf TOI-771
G. Lacedelli, E. Pallé, Y. T. Davis +24
The origin and evolution of the sub-Neptune population is a highly debated topic in the exoplanet community. With the advent of JWST, atmospheric studies can now put unprecedented…
Homogeneous planet masses I: Reanalysis of archival HARPS radial velocities
H. L. M. Osborne, L. D. Nielsen, V. Van Eylen +1
Empirical exoplanet mass-radius relations have been used to study the demographics and compositions of small exoplanets for many years. However, the heterogeneous nature of these m…
HD 119130 b is not an "ultra-dense" sub-Neptune
Joseph M. Akana Murphy, Rafael Luque, Natalie M. Batalha +13
We present a revised mass measurement for HD 119130 b (aka K2-292 b), a transiting planet ( days, ) orbiting a chro…
TOI-757 b: an eccentric transiting mini-Neptune on a 17.5-d orbit
A. Alqasim, N. Grieves, N. M. Rosário +129
We report the spectroscopic confirmation and fundamental properties of TOI-757 b, a mini-Neptune on a 17.5-day orbit transiting a bright star ( mag) discovered by the TESS…
TOI-1408: Discovery and Photodynamical Modeling of a Small Inner Companion to a Hot Jupiter Revealed by TTVs
Judith Korth, Priyanka Chaturvedi, Hannu Parviainen +60
We report the discovery and characterization of a small planet, TOI-1408 c, on a 2.2-day orbit located interior to a previously known hot Jupiter, TOI-1408 b ( d, $M=1.86\p…
