Checked 2026-10-12 09:26 on NVIDIA GeForce RTX 4070, using every TESS sector of this star. All results (.json)

Notes

Found automatically by hunt.py in TESS sector 27 (flagged in 2 sector(s)). Detection score 619.5. 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: 2026-10-09 Gaia hints at a hidden companion star (RUWE 1.9) 2026-10-09 Found by the automatic search in TESS sector 13
