Overview
- Astronomers report two confirmed warm Earth-sized planets, TOI-2267b and TOI-2267c, and a third Earth-sized candidate in the M-dwarf binary TOI-2267.
- The confirmed planets have orbital periods of about 2.28 and 3.49 days, while the candidate shows a 2.03-day signal.
- Transits are detected around both stars in the pair, marking the first confirmed system with planets crossing each stellar component.
- Signals were uncovered by reprocessing TESS data with the SHERLOCK tool and validated with rapid ground-based follow-up from the SPECULOOS and TRAPPIST networks.
- Key details remain under investigation, including definitive host-star assignments for the confirmed planets, mass measurements, and further characterization in follow-up observations.
