The Longest-period Young Transiting Exoplanets. A Duo of Puffy Giants inside a Debris Disk
Carlos del Burgo, Alejandro Suárez Mascareño, Ana Heras Pastor +35
We identify two large-radius planets around the F-type star HD 114082 as the longest-period young transiting exoplanets known. From the first transit, detected by NASA's Transiting…
NGTS-39 b: A 58 d transiting warm Jupiter in an eccentric orbit
Ioannis Apergis, Daniel Bayliss, Solène Ulmer-Moll +53
We report the discovery and characterisation of NGTS-39 b (TIC 453147896 b), a warm Jupiter transiting a Sun-like star on a 58.2 day, eccentric (e = 0.386 +/- 0.019) orbit. NGTS-39…
Observing a 542-day transiting giant with large TTVs: The 2025 transit of HIP 41378 f and new constraints on the outer system
Pietro Leonardi, Alexandre Santerne, Luca Borsato +27
Characterizing long-period transiting exoplanets is inherently challenging due to the rarity and long duration of transit events. Yet, these systems provide unique insights into pl…
Transit timing and starspot-induced transit depth variations in the 17 Myr old HIP 67522 system
H. Chakraborty, M. Lendl, A. Nigioni +27
HIP 67522 is a one of the youngest multi-planetary systems discovered to date. The 17 Myr-old, Sun-like star is part of the Scorpius-Centarus OB association and is known to host tw…
TIC-65910228 b / NGTS-38 b, a 180 day transiting warm super-Jupiter
Toby Rodel, Solène Ulmer-Moll, Samuel Gill +63
We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of R and a mass of M on a long-…
The Neptunian ridge planet WASP-156 b does not have a polar orbit
M. Lafarga, J. I. Espinoza-Retamal, H. M. Cegla +25
The population of short-period exo-Neptunes is thought to be shaped by an interplay between different dynamical mechanisms, such as orbital migration and tidal effects, and photoev…
