TOI-3862 b: A dense super-Neptune deep in the hot Neptune desert
Ilaria Carleo, Amadeo Castro-González, Enric Pallé +61
The structure and evolution of close-in exoplanets are shaped by atmospheric loss and migration processes, which give rise to key population features such as the hot Neptune desert…

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…
