The Rossiter-McLaughlin effect Revolutions: An ultra-short period planet and a warm mini-Neptune on perpendicular orbits

V. Bourrier, C. Lovis, M. Cretignier +34

Comparisons of the alignment of exoplanets with a common host star can be used to distinguish among concurrent evolution scenarios. However, multi-planet systems usually host mini-…

A HARPS-N mass for the elusive Kepler-37d: a case study in disentangling stellar activity and planetary signals

V. M. Rajpaul, L. A. Buchhave, G. Lacedelli +22

To date, only 18 exoplanets with radial velocity (RV) semi-amplitudes m/s have had their masses directly constrained. The biggest obstacle to RV detection of such exoplanets i…

Into the Storm: Diving into the winds of the ultra hot Jupiter WASP-76 b with HARPS and ESPRESSO

J. V. Seidel, D. Ehrenreich, A. Allart +26

Despite swift progress in the characterisation of exoplanet atmospheres in composition and structure, the study of atmospheric dynamics has not progressed at the same speed. While…

TOI-674b: an oasis in the desert of exo-Neptunes transiting a nearby M dwarf

F. Murgas, N. Astudillo-Defru, X. Bonfils +59

We use TESS, Spitzer, ground-based light curves and HARPS spectrograph radial velocity measurements to establish the physical properties of the transiting exoplanet candidate TOI-6…

The CARMENES search for exoplanets around M dwarfs. Two terrestrial planets orbiting G 264-012 and one terrestrial planet orbiting Gl 393

P. J. Amado, F. F. Bauer, C. Rodríguez López +51

We report the discovery of two planetary systems, namely G 264-012, an M4.0 dwarf with two terrestrial planets ( M and $M_{\rm c…

TOI-269 b: An eccentric sub-Neptune transiting a M2 dwarf revisited with ExTrA

M. Cointepas, J. M. Almenara, X. Bonfils +59

We present the confirmation of a new sub-Neptune close to the transition between super-Earths and sub-Neptunes transiting the M2 dwarf TOI- 269 (TIC 220479565, V = 14.4 mag, J = 10…
