TOI-2015b: a sub-Neptune in strong gravitational interaction with an outer non-transiting planet
K. Barkaoui, J. Korth, E. Gaidos +119
TOI-2015 is a known exoplanetary system around an M4 dwarf star, consisting of a transiting sub-Neptune planet in a 3.35-day orbital period, TOI-2015b, accompanied by a non-transit…
TESS discovery of a super-Earth orbiting the M dwarf star TOI-1680
M. Ghachoui, A. Soubkiou, R. D. Wells +52
We report the discovery by the TESS mission of a super-Earth on a 4.8-d orbit around an inactive M4.5 dwarf (TOI-1680) validated by ground-based facilities. The host star is locate…
TOI-2084 b and TOI-4184 b: two new sub-Neptunes around M dwarf stars
K. Barkaoui, M. Timmermans, A. Soubkiou +67
We present the discovery and validation of two TESS exoplanets orbiting nearby M dwarfs: TOI-2084b, and TOI-4184b. We characterized the host stars by combining spectra from Shane/K…
A super-Earth and a mini-Neptune near the 2:1 MMR straddling the radius valley around the nearby mid-M dwarf TOI-2096
F. J. Pozuelos, M. Timmermans, B. V. Rackham +72
Several planetary formation models have been proposed to explain the observed abundance and variety of compositions of super-Earths and mini-Neptunes. In this context, multitransit…
GJ 806 (TOI-4481): A bright nearby multi-planetary system with a transiting hot, low-density super-Earth
E. Palle, J. Orell-Miquel, M. Brady +63
One of the main scientific goals of the TESS mission is the discovery of transiting small planets around the closest and brightest stars in the sky. Here, using data from the CARME…
Two temperate super-Earths transiting a nearby late-type M dwarf
L. Delrez, C. A. Murray, F. J. Pozuelos +82
In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M dwarfs provide unique opportunities for characterising their atmospheres, as well as searching fo…
Weak evidence for variable occultation depth of 55 Cnc e with TESS
E. A. Meier Valdés, B. M. Morris, R. D. Wells +2
55 Cnc e is in a 0.73 day orbit transiting a Sun-like star. It has been observed that the occultation depth of this Super-Earth, with a mass of 8 and radius of 2$R_{…
Uncovering the true periods of the young sub-Neptunes orbiting TOI-2076
Hugh P. Osborn, Andrea Bonfanti, Davide Gandolfi +93
Context: TOI-2076 is a transiting three-planet system of sub-Neptunes orbiting a bright (G = 8.9 mag), young ( Myr) K-type star. Although a validated planetary system, th…
TOI-2257 b: A highly eccentric long-period sub-Neptune transiting a nearby M dwarf
N. Schanche, F. J. Pozuelos, M. N. Günther +61
Thanks to the relative ease of finding and characterizing small planets around M dwarf stars, these objects have become cornerstones in the field of exoplanet studies. The current…
A large sub-Neptune transiting the thick-disk M4V TOI-2406
R. D. Wells, B. V. Rackham, N. Schanche +71
Large sub-Neptunes are uncommon around the coolest stars in the Galaxy and are rarer still around those that are metal-poor. However, owing to the large planet-to-star radius ratio…
