Rare & notable finds

A notable find: not unheard of, but the kind of system astronomers are glad to have more of. 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 21.6 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).

Checked, nothing found (9)

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

Notes

Probably noise or an instrument effect. Notable: Ultra-short-period planet. See the Rare & notable finds section. Found automatically by hunt.py in TESS sector 23 (flagged in 1 sector(s)). Detection score 77.2. 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.
