TOI-3664 b, TOI-4034 b & TOI-6564 b: Three new hot Jupiters around stars approaching the terminal age main sequence
Matthew P. Battley, Marina Lafarga, Edward Gillen +21
Studying the evolution of hot Jupiters requires a sample of well-characterised systems across all evolutionary states. We present three new gas giant exoplanets around stars approa…
TOI-4552 b: A new ultra-short period rocky world revealed by NIRPS and TESS
Avidaan Srivastava, René Doyon, François Bouchy +57
A particularly intriguing subclass of rocky exoplanets are the ultra-short period (USP) worlds that orbit their host stars in less than a day. These planets are particularly rare a…
NIRPS tightens the mass estimate of GJ 3090 b and detects a planet near the stellar rotation period

NIRPS and TESS reveal a peculiar system around the M dwarf TOI-756: A transiting sub-Neptune and a cold eccentric giant
Léna Parc, François Bouchy, Neil J. Cook +148
The Near InfraRed Planet Searcher (NIRPS) joined HARPS on the 3.6-m ESO telescope at La Silla Observatory in April 2023, dedicating part of its Guaranteed Time Observations (GTO) p…
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…

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…
Leveraging Machine Learning for Accurate and Fast Stellar Mass Estimation of Galaxies
