Eclipsing binaryNotable, already known

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 HD 350849 (EA, 43" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable HD 350849. The rare-find check confirms what is on record - still nice, but not a new discovery.

Transits of a giant star notable
Gaia places this star among the giants: planets transiting giants are rare, and a big star makes even a large planet's dip tiny.

Checked, nothing found (6)

Microlensing (rogue planet?) · Exocomet-shaped dip · Eclipse timing (third body?) · Eclipses changing depth · Pulsating star in an eclipsing binary · Extra dips outside the eclipses

Notes

Notable, already known: Transits of a giant star (the catalogued variable HD 350849 (EA, 43" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable HD 350849). WARNING: same period as the known variable HD 350849 43" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 14 (flagged in 1 sector(s)). Detection score 608.1. 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. Updates: 2026-10-12 Rare-find check: Transits of a giant star 2026-10-09 Found by the automatic search in TESS sector 14
