Two Hot sub-Neptunes On A Close-in, eccentric orbit (TOI-5800 b) and a farther-out, circular orbit (TOI-5817 b)
Neptune-sized exoplanets are key targets for atmospheric studies, yet their formation and evolution remain poorly understood due to their diverse characteristics and limited sample size.

An Eccentric Sub-Neptune Moving Into the Evaporation Desert
Though missions such as Kepler, K2, and TESS have discovered >2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P≲3 days) orbits.

Searching for GEMS: Confirmation of TOI-5573b, a Cool, Saturn-like Planet Orbiting An M-dwarf
We present the confirmation of TOI-5573 b, a Saturn-sized exoplanet on an 8.79-day orbit around an early M-dwarf (3790 K, 0.59 R⊙, 0.61 M⊙, 12.30 J mag). TOI-5573 b has […]

TESS Investigation -Demographics of Young Exoplanets (TI-DYE) III: An Inner Super-Earth In TOI-2076
Young (<500 Myr) multi-planet transiting systems are valuable environments for understanding planet evolution by offering an opportunity to make direct comparisons between planets from the same formation conditions.

A Search for Exoplanet Candidates in TESS 2-min Light Curves using Joint Bayesian Detection
In this work, we apply an exploratory joint Bayesian transit detector (Taaki et al. 2020), previously evaluated using Kepler data, to the 2 min simple aperture photometry light curve data […]
