TOI-2267A Archives - Astrobiology

Phased-folded and 2-minute binned TESS light curve (left panel) and detrended Palomar/WIRC light curves (middle and right panels) for the two transit observations of TOI-2267 d. Residuals after the best-fit transit light curve model has been subtracted are shown in the lower panels. Unbinned data are shown as grey circles, with 10 minute binned points overplotted as black circles. The best joint-fit transit models are overplotted as blue lines for the TESS data and red lines for the Palomar data, with 100 random draws from the posterior distribution to illustrate the typical model uncertainty. All detrended light curves are available electronically as data behind the figure. -- astro-ph.EP

Validation Of A Third Earth-sized Planet In The TOI-2267 Binary System

by Keith CowingDecember 13, 2025December 13, 2025

We report the validation of a third terrestrial exoplanet in the nearby (22 pc) TOI-2267 system.

MATRIX injection-and-recovery experiment conducted to establish the detection limits using the ten TESS sectors described in Sect. 3.1. We explored a total of 18000 different scenarios, where each pixel evaluated 40 of them. Color indicates recovery rate: bright yellow for high recovery, dark purple/black for low recovery. The solid blue line indicates the 95% recovery contour, the dashed white line marks the 50%, and the solid white line corresponds to the 5%. Blue, red, and green points show planets b and c, and candidate .02, respectively. Blackedged circles denote planets orbiting the primary star; edge-free circles indicate the secondary star. -- astro-ph.EP

Two Warm Earth-sized Exoplanets And An Earth-sized Candidate In The M5V-M6V Binary System TOI-2267

by Keith CowingNovember 25, 2025November 25, 2025

We report the discovery of two “warm” exoplanets orbiting a very tight pair of small, cool stars called TOI-2267.
