TIC 65450588
Eclipsing binaryKnown to NASA (TOI)
Notes
Already known to NASA: CTOI 65450588.01 (PC).
Already on NASA's TESS list as CTOI 65450588.01 (PC).
NOTE: SIMBAD already lists this star (TYC 6437-292-1) as type SB*, so it may be known after all - check the SIMBAD references.
Found automatically by hunt.py in TESS sector 4 (flagged in 1 sector(s)). Detection score 89.2.
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.
