A hot sub-Neptune in the desert and a temperate super-Earth around faint M dwarfs: Color validation of TOI-4479b and TOI-2081b

E. Esparza-Borges, H. Parviainen, F. Murgas +45

We report the discovery and validation of two TESS exoplanets orbiting faint M dwarfs: TOI-4479b and TOI-2081b. We have jointly analyzed space (TESS mission) and ground based (MuSC…

HD207897 b: A dense sub-Neptune transiting a nearby and bright K-type star

N. Heidari, I. Boisse, J. Orell-Mique +90

We present the discovery and characterization of a transiting sub-Neptune orbiting with a 16.20 day period around a nearby (28 pc) and bright(V=8.37) K0V star HD207897 (TOI-1611).…

HARPS-N, TESS, and CHEOPS discover a transiting sub-Neptune and two outer companions around the bright solar analogue HD 85426

F. Lienhard, A. Mortier, A. Collier Cameron +96

We provide a detailed characterisation of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (: 0.99 ; : 1.13 $\text{R…

TOI-1759 b: a transiting sub-Neptune around a low mass star characterized with SPIRou and TESS

Eder Martioli, Guillaume Hébrard, Pascal Fouqué +57

We report the detection and characterization of the transiting sub-Neptune TOI-1759 b, using photometric time-series from TESS and near infrared spectropolarimetric data from SPIRo…

A planetary system with a sub-Neptune planet in the habitable zone of TOI-2093

J. Sanz-Forcada, E. González-Álvarez, M. R. Zapatero Osorio +33

Aims. We aim to confirm and measure the mass of the transiting planet candidate around the K5V star TOI-2093, previously announced by the Transiting Exoplanet Survey Satellite (TES…

The excitation of rogue waves in a variable medium: an experimental study on the interaction of water waves and currents

A. Toffoli, T. Waseda, H. Houtani +4

We show experimentally that a stable wave propagating into a region characterized by an opposite current may become modulationaly unstable. Experiments have been performed in two i…

TESS and HARPS reveal two sub-Neptunes around TOI 1062

J. F. Otegi, F. Bouchy, R. Helled +46

The Transiting Exoplanet Survey Satellite (\textit{TESS}) mission was designed to perform an all-sky search of planets around bright and nearby stars. Here we report the discovery…

The young HD 73583 (TOI-560) planetary system: Two 10-M mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf

O. Barragán, D. J. Armstrong, D. Gandolfi +103

We present the discovery and characterisation of two transiting planets observed by \textit{TESS} in the light curves of the young and bright (V=9.67) star HD73583 (TOI-560). We pe…

Early Results from the HUMDRUM Survey: A Small, Earth-mass Planet Orbits TOI-1450A

M. Brady, J. Bean, A. Seifahrt +23

M dwarf stars provide us with an ideal opportunity to study nearby small planets. The HUMDRUM (HUnting for M Dwarf Rocky planets Using MAROON-X) survey uses the MAROON-X spectrogra…
