We present an updated characterization of the TOI-1685 planetary system, which consists of a P _b = 0.69 day ultra-short-period super-Earth planet orbiting a nearby ( d = 37.6 pc) M2.5V star (TIC 28900646, 2MASS J04342248+4302148). This planet was pr

The recent discoveries of Neptune-sized ultra-short-period planets (USPs) challenge existing planet formation theories. It is unclear whether these residents of the Hot Neptune Desert have similar origins to smaller, rocky USPs, or if this discrete p

We report the discovery of TOI-700 e, a 0.95 R _⊕ planet residing in the Optimistic Habitable Zone (HZ) of its host star. This discovery was enabled by multiple years of monitoring from NASA’s Transiting Exoplanet Survey Satellite (TESS) mission.

The demographics of young exoplanets can shed light on their formation and evolution processes. Exoplanet properties are derived from the properties of their host stars. As such, it is important to accurately characterize the host stars since any sys
