Revised Masses for Low-density Planets Orbiting the Disordered M-dwarf System TOI-1266

The Astronomical Journal
We present an analysis of 126 new radial velocity measurements from the MAROON-X spectrograph to investigate the TOI-1266 system, which hosts two known transiting sub-Neptunes at 10.8 and 18.8 days.

Enhanced Stability in Planetary Systems with Similar Masses

The Astronomical Journal
This study employs numerical simulations to explore the relationship between the dynamical instability of planetary systems and the uniformity of planetary masses within the system, quantified by the Gini index.

White dwarf systems: Exoplanets and debris disks

Although there is abundant and diverse observational evidence in support of white dwarf stars hosting planets or debris disks which form in the catastrophic destruction of various planetary bodies, the key processes that explain these observations are still being intensely investigated.

The CUISINES Framework for Conducting Exoplanet Model Intercomparison Projects, Version 1.0

The Planetary Science Journal
As JWST begins to return observations, it is more important than ever that exoplanet climate models can consistently and correctly predict the observability of exoplanets, retrieval of their data, and interpretation of planetary environments from that ...
