Rare & notable finds

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

Already known: the catalogued variable V0441 Cep (EA, 129" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable V0441 Cep. 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 85% 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: Changing transit depth; Lopsided transit (the catalogued variable V0441 Cep (EA, 129" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable V0441 Cep). WARNING: same period as the known variable V0441 Cep 129" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 24 (flagged in 3 sector(s)). Detection score 347.8. 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: 2026-10-11 Planet check: Probably noise or an instrument effect 2026-10-11 Rare-find check: Changing transit depth; Lopsided transit 2026-10-11 Found by the automatic search in TESS sector 24
