Validating the Orbital Periods of the Coolest TESS Exoplanet Candidates
When an exoplanet passes in front of its host star, the resulting eclipse causes an observable decrease in stellar flux, and when multiple such transits are detected, the orbital period […]

Precise Density Measurement of TOI-1430 b, A Young Planet With An Evaporating Atmosphere
Small-sized exoplanets in tight orbits around young stars (10-1000 Myr) give us the opportunity to investigate the mechanisms that led to their formation, the evolution of their physical and orbital […]

Examining The Rotation Of The Planet-hosting M Dwarf GJ 3942
Based on radial velocities, EXORAP photometry, and activity indicators, the HADES team reported a 16.3-day rotation period for the M dwarf GJ 3992. However, an RV–Hα magnitude-squared coherence estimate has […]
