Rare & notable finds

Something unusual, worth a look - less certain than a significant find. How these checks work →

Already known: in SIMBAD as TYC 2985-256-1 (*). The rare-find check confirms what is on record - still nice, but not a new discovery.

Changing transit depth hint
The dip depth changes by 26% between transits - a disintegrating planet trailing dust, starspots, or light from another star mixing in.
Lopsided transit hint
The end of the transit is deeper than the start: a dust tail (disintegrating planet), rings, a fast-spinning star, or a blend.

Checked, nothing found (8)

Notes

Probably noise or an instrument effect. Rare, already known: Changing transit depth; Lopsided transit (in SIMBAD as TYC 2985-256-1 (*)). Found automatically by hunt.py in TESS sector 21 (flagged in 1 sector(s)). Detection score 93.5. 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.
