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 V0482 Per (EA/DM:, 60" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable V0482 Per. The rare-find check confirms what is on record - still nice, but not a new discovery.

Eccentric eclipsing binary notable
The second eclipse comes at phase 0.207 instead of 0.5: the orbit is stretched (eccentricity at least 0.460). Eccentric binaries show how tides shape orbits, and their slowly turning orbits test General Relativity.

Notes

Notable, already known: Eccentric eclipsing binary (the catalogued variable V0482 Per (EA/DM:, 60" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable V0482 Per). WARNING: same period as the known variable V0482 Per 60" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 19 (flagged in 1 sector(s)). Detection score 1179.0. 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: 2026-10-11 Rare-find check: Eccentric eclipsing binary 2026-10-11 Found by the automatic search in TESS sector 19
