Validation of a Third Earth-sized Planet in the TOI-2267 Binary System
Michael Greklek-McKeon, Jonathan Gomez Barrientos, Heather A. Knutson +13
We report the validation of a third terrestrial exoplanet in the nearby (22 pc) TOI-2267 system. TOI-2267 is a binary system with stellar components TOI-2267A (M5, 3030 K) and TOI-…
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…
WATSON-Net: Vetting, Validation, and Analysis of Transits from Space Observations with Neural Networks
M. Dévora-Pajares, F. J. Pozuelos, J. C. Suárez +2
Context. As the number of detected transiting exoplanet candidates continues to grow, the need for robust and scalable automated tools to prioritize or validate them has become inc…
The Atmospheric Composition of Sub-Neptune K2-18 b and Implications for its Formation
Gareb Fernández-Rodríguez, Giuseppe Morello, Jonathan C. Tan +8
Unlocking the atmospheres of sub-Neptunes is among JWST's major achievements, yet such observations demand complex analyses that strongly affect interpretations. We present an inde…
NGTS-11 c: a transiting Neptune-mass planet interior to the warm Saturn NGTS-11 b
David R. Anderson, Jose I. Vines, Katharine Hesse +56
We report the discovery of NGTS-11 c, a transiting warm Neptune ( d; ; ), in an…
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.…
Two warm Earth-sized exoplanets and an Earth-sized candidate in the M5V-M6V binary system TOI-2267
S. Zúñiga-Fernández, F. J. Pozuelos, M. Dévora-Pajares +63
We report two warm Earth-sized exoplanets orbiting the close binary TOI-2267 (M5+M6, separation ~8 au). Data from TESS and ground-based facilities confirm the planets, but we canno…
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…
Sibling Sub-Neptunes Around Sibling M Dwarfs: TOI-521 and TOI-912
G. Lacedelli, E. Pallé, R. Luque +47
Sub-Neptunes are absent in the Solar System, yet they are commonly found in our Galaxy. They challenge the internal structure models and prompt investigation on their formation, ev…
Interior redox state effects on the stability of secondary atmospheres and observational manifestations: LP 791-18 d as a case study for outgassing rocky exoplanets
Leonardos Gkouvelis, Francisco J. Pozuelos, Thomas Drant +3
Recent advances in space and ground-based facilities now enable atmospheric characterization of a selected sample of rocky exoplanets. These atmospheres offer key insights into pla…
A transiting giant planet in orbit around a 0.2-solar-mass host star
Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56
Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…
TOI-2407 b: a warm Neptune in the desert
C. Janó Muñoz, M. J. Hooton, P. P. Pedersen +22
We present the validation of TOI-2407 b, a warm Neptune-sized planet with a radius of 4.26 0.26 R, orbiting an early M-type star with a period of 2.7 days and an equ…
Three Hot Jupiters transiting K-dwarfs with a significant heavy element mass
Y. G. C. Frensch, F. Bouchy, G. Lo Curto +50
Albeit at a lower frequency than around hotter stars, short-period gas giants around low-mass stars ( K) do exist, despite predictions from planetary populat…
A transiting rocky super-Earth and a non-transiting sub-Neptune orbiting the M dwarf TOI-771
G. Lacedelli, E. Pallé, Y. T. Davis +24
The origin and evolution of the sub-Neptune population is a highly debated topic in the exoplanet community. With the advent of JWST, atmospheric studies can now put unprecedented…
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…
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…
