TOI-6981 b: a transiting sub-Neptune at the water ice line

Madison G. Scott, Amaury H. M. J Triaud, Emily K. Pass +42

We present TOI-6981 b, a cold (Teq= 170.0 +/-4.5 K, assuming an Earth-like albedo) sub-Neptune (Rb=2.40+/-0.10 R_oplus) on a 60.8 day orbit around around its M4-type host star (R*=…

TOI-7166 b: A Habitable Zone mini-Neptune planet around a nearby low-mass star

Khalid Barkaoui, Francisco J. Pozuelos, Benjamin V. Rackham +41

We present the discovery and validation of TOI-7166b, a 2.01+/-0.05R_Earth planet orbiting a nearby low-mass star. We validated the planet by combining TESS and multi-color high-pr…

MANGOS II: Five new giant planets orbiting low-mass stars

G. Dransfield, M. Timmermans, D. Sebastian +47

Giant planets orbiting low-mass stars on short orbits present a conundrum, as in the most extreme cases their existence cannot be reconciled with current models of core accretion.…

TOI-1743 b, TOI-5799 b, TOI-5799 c and TOI-6223 b: TESS discovery and validation of four super-Earth to Neptune-sized planets around M dwarfs

S. Yalçınkaya, K. Barkaoui, Ö. Baştürk +62

We present the discovery by the TESS mission of one transiting Neptune-sized planet, TOI-6223 b and two transiting super-Earths, TOI-1743 b and TOI-5799 b. We validate these planet…

TOI-1846b: A super-Earth in the radius valley orbiting a nearby M dwarf

Abderahmane Soubkiou, Khalid Barkaoui, Zouhair Benkhaldoun +42

We present the discovery and validation of a super-Earth planet orbiting the M dwarf star TOI-1846 (TIC 198385543). The host star(Kmag = 9.6)is located 47 pc away and has a radius…

TOI-6478 b: a cold under-dense Neptune transiting a fully convective M dwarf from the thick disc

Madison G. Scott, Amaury H. M. J. Triaud, Khalid Barkaoui +25

Growing numbers of exoplanet detections continue to reveal the diverse nature of planetary systems. Planet formation around late-type M dwarfs is of particular interest. These syst…

TOI-6508b: A massive transiting brown dwarf orbiting a low-mass star

K. Barkaoui, D. Sebastian, S. Zúñiga-Fernández +44

We report the discovery of a transiting brown dwarf orbiting a low-mass star, TOI-6508b. Today, only ~50 transiting brown dwarfs have been discovered. TOI-6508b was first detected…

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…

Three short-period Earth-sized planets around M dwarfs discovered by TESS: TOI-5720b, TOI-6008b and TOI-6086b

K. Barkaoui, R. P. Schwarz, N. Narita +53

One of the main goals of the NASA's TESS (Transiting Exoplanet Survey Satellite) mission is the discovery of Earth-like planets around nearby M-dwarf stars. Here, we present the di…
