Eclipsing binaryRare, already known
Rare & notable finds
Something unusual, worth a look - less certain than a significant find. How these checks work →
Already known: in SIMBAD as HD 234691 (PM*). The rare-find check confirms what is on record - still nice, but not a new discovery.
- Extra dips outside the eclipses hint
1 dip(s) that don't belong to the eclipses (at BTJD 3479.96): a planet orbiting both stars (circumbinary, like Kepler-16b) makes dips at irregular times, or a third star.
Checked, nothing found (11)

Notes
Rare, already known: Extra dips outside the eclipses (in SIMBAD as HD 234691 (PM*)).
Found automatically by hunt.py in TESS sector 19 (flagged in 5 sector(s)). Detection score 476.0.
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.
