The small transiting planet population revealed by ESPRESSO with extreme precision radial velocities
M. J. Hobson, B. Lavie, F. Bouchy +35
Small planets are extremely common in the Galaxy, including planets with masses and radii between those of Earth and Neptune. Characterizing these planets' masses requires ultra-pr…
TOI-2322: two transiting rocky planets close to the stellar rotation period and its first harmonic
M. J. Hobson, A. Suárez Mascareño, C. Lovis +42
Context. Active regions on the stellar surface can induce quasi-periodic radial velocity (RV) variations that can mimic planets and mask true planetary signals. These spurious sign…
TOI-512: Super-Earth transiting a K-type star discovered by TESS and ESPRESSO
J. Rodrigues, S. C. Barros, N. C. Santos +38
One of the goals of the ESPRESSO guaranteed time observations (GTOs) at the ESO 8.2m telescope is to follow up on candidate planets from transit surveys such as the TESS mission. H…
A sub-Earth-mass planet orbiting Barnard's star
J. I. Gonzalez Hernandez, A. Suarez Mascareno, A. M. Silva +37
Barnard's star is a primary target within the ESPRESSO guaranteed time observations (GTO) as it is the second closest neighbour to our Sun after the Centauri stellar system. W…
