TOI-283 b: A transiting mini-Neptune in a 17.6-day orbit discovered with TESS and ESPRESSO

F. Murgas, E. Pallé, A. Suárez Mascareño +51

Super-Earths and mini-Neptunes are missing from our Solar System, yet they appear to be the most abundant planetary types in our Galaxy. A detailed characterization of key planets…

Two neighbours of the ultra-short-period Earth-sized planet K2-157 b in the warm Neptunian savanna

A. Castro-González, F. Bouchy, A. C. M. Correia +30

The formation and evolution of ultra-short-period (USP) planets is poorly understood. However, it is widely thought that these planets migrated inwards through interactions with ou…

Detection of a high-velocity sodium feature on the ultra-hot Jupiter WASP-121 b

J. V. Seidel, F. Borsa, L. Pino +19

Ultra-hot Jupiters, with their high equilibrium temperatures and resolved spectral lines, have emerged as a perfect testbed for new analysis techniques in the study of exoplanet at…

HD 23472: A multi-planetary system with three super-Earths and two potential super-Mercuries

S. C. C. Barros, O. D. S. Demangeon, Y. Alibert +7

We report the characterisation of a multi-planetary system composed of five exoplanets orbiting the K-dwarf HD~23472 (TOI-174). In addition to the two super-Earths that were previo…

Measurements of Omega and Lambda from 42 High-Redshift Supernovae

S. Perlmutter, G. Aldering, G. Goldhaber +29

We report measurements of the mass density, Omega_M, and cosmological-constant energy density, Omega_Lambda, of the universe based on the analysis of 42 Type Ia supernovae discover…
