Rare & notable finds

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

Already known: catalogued variable star nearby: Gaia DR3 1999365412968790016 (S), 59" away; in the ATLAS variable-star catalogue (Heinze et al. 2018) as J357.3699+58.8578. The rare-find check confirms what is on record - still nice, but not a new discovery.

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.
Transits of a giant star notable
Gaia places this star among the giants: planets transiting giants are rare, and a big star makes even a large planet's dip tiny.

Notes

Probably noise or an instrument effect. Rare, already known: Lopsided transit; Transits of a giant star (catalogued variable star nearby: Gaia DR3 1999365412968790016 (S), 59" away; in the ATLAS variable-star catalogue (Heinze et al. 2018) as J357.3699+58.8578). Found automatically by hunt.py in TESS sector 17 (flagged in 2 sector(s)). Detection score 262.6. 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.
