GJ 523b Is A Massive, 170 Myr-old Mega-Earth, Likely On A Polar Orbit
We use WIYN/NEID radial velocity measurements to confirm the planetary nature and measure the mass of the TESS transiting exoplanet candidate around the mid-K dwarf GJ 523 (V=9.23, K=6.525).

Automatic Search For Transiting Planets In TESS-SPOC FFIs With RAVEN: Over 100 Newly Validated Planets And Over 2000 Vetted Candidates
Space-based missions such as TESS are identifying a wealth of short-period (≲30 d) transiting planets. Despite the growing number of confirmed and candidate planets, the sample is still incomplete and […]

How Open NASA Data on Comet 3I/ATLAS Will Power Tomorrow’s Discoveries
The interstellar comet 3I/ATLAS will soon leave our solar system, never to return, but the observations of the comet will live on in NASA’s public data archives. More than a […]

TOI-4552 b: A New Ultra-short Period Rocky World Revealed By NIRPS And TESS
A particularly intriguing subclass of rocky exoplanets are the ultra-short period (USP) worlds that orbit their host stars in less than a day. These planets are particularly rare around M […]

TOI-4616 b: A Benchmark Earth-sized Planet Transiting A Nearby M4 Dwarf
Rocky exoplanets are particularly abundant around M-type stars. Their small radii and low luminosities provide favourable conditions for detecting transiting terrestrial planets and probing their atmospheric properties.

TOI-1080 b: A Temperate, Rocky Planet Orbiting A Quiet M4V Host
We present the detection and validation of a small, temperate transiting exoplanet orbiting TOI-1080 every 3.9652482+0.0000014−0.0000015 days. The host is a quiet M4V star at 25.6 pc.

TESS Planet Occurrence Rates Reveal the Disappearance of the Radius Valley Around Mid-to-Late M Dwarfs
We present the deepest systematic search for planets around mid-to-late M dwarfs to date. We have surveyed 8134 mid-to-late M dwarfs observed by TESS with a custom built pipeline and […]
