Checked 2026-10-11 16:29 on NVIDIA GeForce RTX 4070, using every TESS sector of this star. All results (.json)

Notes

Probably noise or an instrument effect. Found automatically by hunt.py in TESS sector 24 (flagged in 1 sector(s)). Detection score 276.1. Not in VSX, ASAS-SN or ZTF variable catalogues at the time of the search; not in Gaia DR3's variable lists. Unchecked by hand yet: verify the period, nearby stars and a wider catalogue search. Updates: 2026-10-11 Planet check: Probably noise or an instrument effect 2026-10-11 Gaia hints at a hidden companion star (RUWE 1.7) 2026-10-11 Found by the automatic search in TESS sector 24
