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 →

Already known: the catalogued variable LINEAR 10446485 (EA, 45" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable LINEAR 10446485. The rare-find check confirms what is on record - still nice, but not a new discovery.

Ultra-short-period planet notable
One orbit takes 10.3 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 (8)

Notes

Probably noise or an instrument effect. Notable, already known: Ultra-short-period planet (the catalogued variable LINEAR 10446485 (EA, 45" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable LINEAR 10446485). WARNING: same period as the known variable LINEAR 10446485 45" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 22 (flagged in 4 sector(s)). Detection score 166.9. 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.
