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-3288 b and TOI-4666 b: two gas giants transiting low-mass stars characterised by NIRPS
Yolanda G. C. Frensch, François Bouchy, Gaspare Lo Curto +62
Gas giant planets orbiting low-mass stars are uncommon outcomes of planet formation. Increasing the sample of well-characterised giants around early M dwarfs will enable population…
A planetary system with a sub-Neptune planet in the habitable zone of TOI-2093
J. Sanz-Forcada, E. González-Álvarez, M. R. Zapatero Osorio +33
Aims. We aim to confirm and measure the mass of the transiting planet candidate around the K5V star TOI-2093, previously announced by the Transiting Exoplanet Survey Satellite (TES…
A transiting hot Jupiter with two outer siblings orbiting an intermediate-mass post main-sequence star
Y. Reinarz, M. I. Jones, R. Brahm +15
Exoplanetary systems with multiple giant planets present an opportunity to understand planet formation, migration processes, and long-term system-wide dynamical interactions. In pa…
Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b
S. Ulmer-Moll, S. Gill, R. Brahm +64
Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measur…
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…
TOI-2322: two transiting rocky planets close to the stellar rotation period and its first harmonic
M. J. Hobson, A. Suárez Mascareño, C. Lovis +42
Context. Active regions on the stellar surface can induce quasi-periodic radial velocity (RV) variations that can mimic planets and mask true planetary signals. These spurious sign…
The Hot Neptune Initiative (HONEI) II. TOI-5795 b: A hot super-Neptune orbiting a metal-poor star
F. Manni, L. Naponiello, L. Mancini +31
The formation of Neptune planets with orbital periods less than 10\,days remains uncertain. They might have developed similarly to longer-period counterparts, emerged from rare col…
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…
The Hot-Neptune Initiative (HONEI) I. Two hot sub-Neptunes on a close-in, eccentric orbit (TOI-5800 b) and a farther-out, circular orbit (TOI-5817 b)
L. Naponiello, S. Vissapragada, A. S. Bonomo +37
Neptune-sized exoplanets are key targets for atmospheric studies, yet their formation and evolution remain poorly understood due to their diverse characteristics and limited sample…
TOI-3493 b: A planet with a Neptune-like density transiting a bright G0-type star
P. Chaturvedi, E. Goffo, D. Gandolfi +23
We report the discovery of TOI-3493 b, a sub-Neptune-sized planet on an 8.15-d orbit transiting the bright (V=9.3) G0 star HD 119355 (aka TIC 203377303) initially identified by NAS…
TESS and HARPS-N unveil two planets transiting TOI-1453. A super-Earth and one of the lowest mass sub-Neptunes
M. Stalport, A. Mortier, M. Cretignier +37
We report on the validation and characterisation of two transiting planets around TOI-1453, a K-dwarf star in the TESS northern continuous viewing zone. In addition to the TESS dat…
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…
