Transit candidateRare, already known

Rare & notable finds

Something genuinely unusual turned up. Treat it as a lead: every one of these has ordinary explanations too, listed with each. How these checks work →

Already known: in SIMBAD as TYC 3443-925-1 (*); catalogued variable star nearby: Gaia DR3 830953752333337216 (ROT), 234" away. The rare-find check confirms what is on record - still nice, but not a new discovery.

Transit timing (TTV) significant
The transits arrive early or late by 4.6 min (typical error 1.3 min) repeating every ~4.8 orbits: something is tugging on the planet - another planet, or a moon.
Changing transit depth hint
The dip depth changes by 18% between transits - a disintegrating planet trailing dust, starspots, or light from another star mixing in.
Lopsided transit hint
The start of the transit is deeper than the end: a dust tail (disintegrating planet), rings, a fast-spinning star, or a blend.

Notes

Probably noise or an instrument effect. Rare, already known: Transit timing (TTV); Changing transit depth; Lopsided transit (in SIMBAD as TYC 3443-925-1 (*); catalogued variable star nearby: Gaia DR3 830953752333337216 (ROT), 234" away). Found automatically by hunt.py in TESS sector 21 (flagged in 1 sector(s)). Detection score 213.0. 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 Rare-find check: Transit timing (TTV); Changing transit depth; Lopsided transit 2026-10-11 Found by the automatic search in TESS sector 21
