Reanalysis Of The Eclipses Of LHS 1140 c: No Evidence Of An Atmosphere And Implications For The Internal Structure Of The Planet
We present the reanalysis of three 15 micron JWST/MIRI secondary eclipses of LHS 1140 c, a warm super-Earth (Rp = 1.272 R⊕) in a 3.78-day orbit around an M4.5 dwarf.

Formation Of Super-Earths Around Low-mass Stars: Evolution Of An Icy Dead Zone
Exoplanet observations show that close-in super-Earths are more common around M-dwarfs than around solar mass stars.

An Ultra-Short Period Super-Earth and Sub-Neptune Spanning the Radius Valley Orbiting the Kinematic Thick Disk Star TOI-2345
A crucial chemical link between stars and their orbiting exoplanets is thought to exist. If universal, this connection could affect the formation and evolution of all planets. Therefore, this potential […]

Exoplanets Are Not Water Worlds
An exoplanet orbiting a dwarf star 124 light-years from Earth made headlines around the world in April 2025. Researchers at the University of Cambridge reported that planet K2-18b could be […]

TOI-1743 b, TOI-5799 b, TOI-5799 c and TOI-6223 b: TESS Discovery And Validation Of Four Super-Earth To Neptune-sized Planets Around M dwarfs
We combined TESS and ground-based photometric data to constrain the physical properties of the planets. TOI-6223-b is slightly larger than Neptune (Rp=5.12+0.24−0.25 R⊕) orbiting an early M dwarf in 3.86 […]

How Stellar Mass And Disc Size Shape The Formation And Migration Of Super-Earths
The occurrence rate of close-in super-Earths is higher around M-dwarfs compared to stars of higher masses.

KMT-2018-BLG-0029Lb and OGLE-2019-BLG-0960Lb: Mass Measurements for Two Super-Earth Microlensing Planets
KMT-2018-BLG-0029Lb and OGLE-2019-BLG-0960Lb were the lowest mass-ratio microlensing planets at the time of discovery. For both events, microlensing parallax measurements from the Spitzer Space Telescope implied lens systems that were […]
