Notes

Probably noise or an instrument effect. NOTE: SIMBAD already lists this star (TYC 1604-1130-1) as type SB*, so it may be known after all - check the SIMBAD references. Found automatically by hunt.py in TESS sector 14 (flagged in 1 sector(s)). Detection score 401.4. 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 2026-10-09 Gaia hints at a hidden companion star (RUWE 1.8) 2026-10-09 Found by the automatic search in TESS sector 14
