An empirical determination of the Cosmic Shoreline
Pedro Meni-Gallardo, Enric Pallé
The cosmic shoreline concept was introduced to separate planets with atmospheres from those without, by relating the cumulative X-ray and extreme-ultraviolet (XUV) instellation (in…
A Ground-Based Transit Observation of the Long-Period Extremely Low-Density Planet HIP 41378 f
Juliana GarcÃa-MejÃa, Zoë L. de Beurs, Patrick Tamburo +25
We present a ground-based transit detection of HIP 41378 f, a long-period ( days), extremely low-density ( g cm) giant exoplanet in a dynamically com…
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-Ãlvarez, 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…
