TOI-2322: Two Transiting Rocky Planets Close To The Stellar Rotation Period And Its First Harmonic
Context. Active regions on the stellar surface can induce quasi-periodic radial velocity (RV) variations that can mimic planets and mask true planetary signals. These spurious signals can be problematic for […]

Discovery Of A Multi-planetary System Orbiting The Aged Sun-like Star HD 224018
In 2016, Kepler/K2 detected a system of two sub-Neptunes transiting the star HD 224018, one of them showing a mono-transit event.

The JWST Rocky Worlds DDT Program Reveals GJ 3929b To Likely Be A Bare Rock
We report first results from the JWST Rocky Worlds Director’s Discretionary Time program. Two secondary eclipses of the terrestrial exoplanet GJ 3929b were recently observed using MIRI photometric imaging at […]

The Mass Of TOI-654 b: A Short-period Sub-Neptune Transiting A Mid-M Dwarf
Sub-Neptunes are small planets between the size of the Earth and Neptune. The orbital and bulk properties of transiting sub-Neptunes can provide clues for their formation and evolution of small […]
