TOI-6884b: A low-mass brown dwarf transiting a slightly evolved star
Akanksha Khandelwal, Shubhendra Nath Das, Rishikesh Sharma +42
We report the discovery of a low-mass transiting brown dwarf orbiting TOI-6884 (TIC~156514476, ) from NASA's \textit{Transiting Exoplanet Survey Satellite} (\text…
TOI-7169 b: A Hot Jupiter Transiting a Metal-Poor Star
Joshua D. Simon, Joseph E. Rodriguez, Jhon Yana Galarza +38
Most known planets are found around metal-rich host stars, which has made it difficult to determine whether a lower metallicity limit for planet formation exists and how the proper…
Multicolour Validation of Two Temperate Mini-Neptunes Around M-dwarf Habitable Zones
Chengzi Jiang, Aleksandra Selezneva, Hannu Parviainen +17
For small planets orbiting within the habitable zones of their host stars, multicolour validation via photometric transit observations offers an efficient alternative to prioritize…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
A young progenitor for the most common planetary systems in the Galaxy
John H. Livingston, Erik A. Petigura, Trevor J. David +39
The Galaxy's most common known planetary systems have several Earth-to-Neptune-size planets in compact orbits. At small orbital separations, larger planets are less common than the…
Validation of TESS Planet Candidates with Multi-Color Transit Photometry and TRICERATOPS+
Jonathan Gomez Barrientos, Michael Greklek-McKeon, Heather A. Knutson +33
We present an upgraded version of TRICERATOPS, a software package designed to calculate false positive probabilities for planet candidates identified by the Transiting Exoplanet Su…
