Checked 2026-10-04 22:18 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 4 (flagged in 1 sector(s)). Detection score 84.8. 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: 2026-10-04 Gaia hints at a hidden companion star (RUWE 1.5) 2026-10-04 Planet check: Probably noise or an instrument effect 2026-10-04 Found by the automatic search in TESS sector 4
