Rare & notable finds

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

Already known: in SIMBAD as UCAC4 604-045285 (*); catalogued variable star nearby: Gaia DR3 699651997881822208 (ROT), 278" away. The rare-find check confirms what is on record - still nice, but not a new discovery.

Ultra-short-period planet notable
One orbit takes 23.1 hours - ultra-short-period planets are found around only ~0.5% of stars (if the signal is a real planet - it hasn't passed the planet check).
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 (9)

Microlensing (rogue planet?) · Exocomet-shaped dip · Habitable zone & size · Transit timing (TTV) · Dimming beside the transit · Trojan companions (L4/L5) · More planets in the system · Self-lensing binary · Type of star

Notes

Probably noise or an instrument effect. Rare, already known: Ultra-short-period planet; Lopsided transit (in SIMBAD as UCAC4 604-045285 (*); catalogued variable star nearby: Gaia DR3 699651997881822208 (ROT), 278" away). Found automatically by hunt.py in TESS sector 21 (flagged in 1 sector(s)). Detection score 290.3. 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.
