Hidden Transits: TOI-2285 b is a Warmer sub-Neptune Likely with a Super-Earth Companion
TOI-2285 b is a sub-Neptune-sized planet orbiting a nearby M dwarf, discovered through the TESS photometric survey and ground-based follow-up observations.

Super-Earth Discovered In The Habitable Zone Of A Sun-Like Star Via TTV Technique
“Are we alone?” This ancient question has occupied humanity’s mind for a long time. In 1995, the discovery of the first exoplanet orbiting a Sun-like star opened the door to […]

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.

Astronomers Find Earth-like Exoplanets Are Common Across The Cosmos
Using the Korea Microlensing Telescope Network (KMTNet), an international team of researchers has discovered that super-Earth exoplanets are more common across the universe than previously thought, according to a new […]

Microlensing Events Indicate That Super-Earth Exoplanets Are Common In Jupiter-like Orbits
Exoplanets classified as super-Earths are commonly observed on short period orbits, close to their host stars, but their abundance on wider orbits is poorly constrained. Gravitational microlensing is sensitive to […]

An Informational-Entropic Approach to Exoplanet Characterization
In the past, measures of “Earth-likeness” of exoplanets have been qualitative, considered an abiotic Earth, or required discretionary choices of what parameters make a planet Earth-like.
