Transit Timing Variations in HIP 41378: CHEOPS and TESS confirm a non-transiting sixth planet in the system

P. Leonardi, L. Borsato, L. Pagliaro +89

In multiple-planet systems, gravitational interactions of exoplanets could lead to transit timing variations (TTVs), whose amplitude becomes significantly enhanced when planets are…

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…

Testing the performance of cross-correlation techniques to search for molecular features in JWST NIRSpec G395H observations of transiting exoplanets

Emma Esparza-Borges, Mercedes López-Morales, Enric Pallé +18

Cross-correlations techniques offer an alternative method to search for molecular species in JWST observations of exoplanet atmospheres. In a previous article, we applied cross-cor…

HARPS-N Reveals a Well-aligned Orbit for the Highly Eccentric Warm Jupiter TOI-4127 b

Ismael Mireles, Felipe Murgas, Diana Dragomir +4

While many hot Jupiter systems have a measured obliquity, few warm Jupiter systems do. The longer orbital periods and transit durations of warm Jupiters make it more difficult to m…

Improved characterization of the TOI-2141 system: a dense sub-Neptune with non-transiting inner and outer companions

R. Luque, K. W. F. Lam, J. Cabrera +87

We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star in a relatively long orbit of 18.26 d…

Discovery of a transiting hot water-world candidate orbiting Ross 176 with TESS and CARMENES

S. Geraldía-González, J. Orell-Miquel, E. Pallé +30

The case of Ross 176 is a late K-type star that hosts a promising water-world candidate planet. The star has a radius of =0.5690.020 and a mass of
