A temperate sub-Neptune transiting the M4 Dwarf TOI-210 identified by NIRPS and TESS -- Uncovering hidden M-dwarf planetary systems in the near-infrared

C. Cadieux, B. N. Skinner, F. Bouchy +63

Super-Earths and sub-Neptunes dominate the exoplanet population, yet their compositions, formation mechanisms, and capability of retaining atmospheres remain poorly understood. M-t…

TS23/McDonald and FIES/NOT strike again. Two new warm Jupiter systems and outer companions in a third

E. Knudstrup, D. Gandolfi, W. D. Cochran +29

Warm Jupiters (gas giant planets with orbital periods of P8-200 d) are thought to be largely unaffected by the tidal interactions that can erase information about the dynamic…

Two extremely irradiated volatile-rich sub-Neptunes with companions in the TOI-426 and TOI-1839 systems: Insights into arrival and survival near the lower edge of the Neptunian desert

A. Castro-González, O. Barragán, D. J. Armstrong +26

Using TESS photometry and 147 HARPS radial velocities, we confirm two extremely irradiated, volatile-rich sub-Neptunes near the lower edge of the Neptunian desert: TOI-426 b and TO…

Refined parameters, formation, and dynamical stability of the wild exoplanet system K2-312=HD 80653

L. Naponiello, E. Poretti, K. Rice +24

The architecture of planetary systems hosting ultra-short-period (USP) planets is a key diagnostic for understanding formation and migration scenarios. The presence of outer giant…

An Ultra-Short Period Super-Earth and a Sub-Neptune Orbiting the K dwarf TOI-4311

Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrew Collier Cameron +95

We report the discovery and characterisation of the multi-planetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disk and Hercules stream. TOI-4311 ho…

TOI-1080 b: a temperate, rocky planet orbiting a quiet M4V host

Y. Gómez Maqueo Chew, G. Dransfield, K. Barkaoui +41

We present the detection and validation of a small, temperate transiting exoplanet orbiting TOI-1080 every 3.9652482 days. The host is a quiet M4V star…
