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.

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.

Small And Large Planets Have Significantly Different Upbringings
The shape of a planet’s orbit is one of its fundamental properties, along with its size and distance from its host star. Earth has a nearly circular orbit, but some […]
