TESS discovery of two super-Earths orbiting the M-dwarf stars TOI-6002 and TOI-5713 near the radius valley

M. Ghachoui, B. V. Rackham, M. Dévora-Pajares +45

We present the validation of two TESS super-Earth candidates transiting the mid-M dwarfs TOI-6002 and TOI-5713 every 10.90 and 10.44 days, respectively. The first star (TOI-6002) i…

TOI-5005 b: A super-Neptune in the savanna near the ridge

A. Castro-González, J. Lillo-Box, D. J. Armstrong +38

The Neptunian desert and savanna have recently been found to be separated by a ridge, an overdensity of planets in the period range of 3-5 days. These features are thought…

Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3

Michaël Gillon, Peter P. Pedersen, Benjamin V. Rackham +81

Located at the bottom of the main sequence, ultracool dwarf stars are widespread in the solar neighbourhood. Nevertheless, their extremely low luminosity has left their planetary p…

TOI-4336 A b: A temperate sub-Neptune ripe for atmospheric characterization in a nearby triple M-dwarf system

M. Timmermans, G. Dransfield, M. Gillon +54

Small planets transiting bright nearby stars are essential to our understanding of the formation and evolution of exoplanetary systems. However, few constitute prime targets for at…

Aperture photometry on asteroid trails: detection of the fastest rotating near-Earth object

Maxime Devogèle, Luca Buzzi, Marco Micheli +9

Context. Near-Earth objects (NEOs) on an impact course with Earth can move at high angular speed. Understanding their properties, including rotation state, is crucial for assessing…

TOI-2266 b: a keystone super-Earth at the edge of the M dwarf radius valley

Hannu Parviainen, Felipe Murgas, Emma Esparza-Borges +59

We validate the Transiting Exoplanet Survey Satellite (TESS) object of interest TOI-2266.01 (TIC 348911) as a small transiting planet (most likely a super-Earth) orbiting a faint M…
