Possible Evidence for the Presence of Volatiles on the Warm Super-Earth TOI-270 b

The Astronomical Journal
The search for atmospheres on rocky exoplanets is a crucial step in understanding the processes driving atmosphere formation, retention, and loss. Past studies have revealed the existence of planets interior to the radius valley with densities lower than

Kepler-discovered Multiple-planet Systems near Period Ratios Suggestive of Mean-motion Resonances Are Young

The Astronomical Journal
Before the launch of the Kepler Space Telescope, models of low-mass planet formation predicted that convergent type I migration would often produce systems of low-mass planets in low-order mean-motion resonances.

The Spin–Orbit Alignment of Eight Warm Gas Giant Systems

The Astronomical Journal
Essential information about the formation and evolution of planetary systems can be found in their architectures—in particular, in stellar obliquity ( ψ )—as they serve as a signature of their dynamical evolution. Here we present ESPRESSO observations of
