Eclipsing binaryRare, already known

Rare & notable finds

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

Already known: the catalogued variable PMAK V62 (EA, 37" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable PMAK V62. 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 0.606 instead of 0.5: the orbit is stretched (eccentricity at least 0.167). Eccentric binaries show how tides shape orbits, and their slowly turning orbits test General Relativity.
Extra dips outside the eclipses hint
1 dip(s) that don't belong to the eclipses (at BTJD 2896.38): a planet orbiting both stars (circumbinary, like Kepler-16b) makes dips at irregular times, or a third star.

Notes

Rare, already known: Eccentric eclipsing binary; Extra dips outside the eclipses (the catalogued variable PMAK V62 (EA, 37" away) has the same period - its light leaks into TESS's big pixels; same period as the known variable PMAK V62). WARNING: same period as the known variable PMAK V62 37" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 14 (flagged in 13 sector(s)). Detection score 731.1. 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: Extra dips outside the eclipses; Eccentric eclipsing binary 2026-10-09 Found by the automatic search in TESS sector 14
