Rare & notable finds

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

Fully unknown: not in SIMBAD, not in Gaia DR3's variable lists, not on NASA's TOI lists, no catalogued variable star within 5′ (VSX, ASAS-SN, ZTF, ATLAS, WISE, TESS EB catalogues) - this may be new.

Ultra-short-period planet notable
One orbit takes 11.5 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 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 (5)

Notes

Probably noise or an instrument effect. Unusual: Ultra-short-period planet; Lopsided transit. See the Rare & notable finds section. Found automatically by hunt.py in TESS sector 23 (flagged in 1 sector(s)). Detection score 203.7. 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.
