Rare & notable finds

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

Already known: in SIMBAD as TYC 2192-1961-1 (*); catalogued variable star nearby: Gaia DR3 1798873766905725184 (ROT, P = 2.6728 d), 138" away. 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.

Checked, nothing found (9)

Microlensing (rogue planet?) · Exocomet-shaped dip · Habitable zone & size · Transit timing (TTV) · Transit duration (TDV) · Changing transit depth · Dimming beside the transit · Trojan companions (L4/L5) · Type of star

Notes

Probably noise or an instrument effect. Rare, already known: Lopsided transit (in SIMBAD as TYC 2192-1961-1 (*); catalogued variable star nearby: Gaia DR3 1798873766905725184 (ROT, P = 2.6728 d), 138" away). Found automatically by hunt.py in TESS sector 15 (flagged in 1 sector(s)). Detection score 170.2. Not in VSX, ASAS-SN or ZTF variable catalogues at the time of the search; Gaia DR3 lists it as a variable-star candidate. Unchecked by hand yet: verify the period, nearby stars and a wider catalogue search.
