Transit candidateProbably known

Notes

Probably noise or an instrument effect. WARNING: same period as the known variable Gaia DR3 4737237159555592320 65" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 4 (flagged in 3 sector(s)). Detection score 55.6. 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: 2026-10-12 Gaia hints at a hidden companion star (RUWE 23.1) 2026-10-12 Planet check: Probably noise or an instrument effect 2026-10-12 Found by the automatic search in TESS sector 4
