V 641 CAS - a Symbiotic Candidate?


The authors suggest two possibilities about V641 Cas: (1) It is a long-period binary (possible eclipsing) consisting of M2-3 bright giant and a main sequence star - similar to VV Cep-type stars. (2) The V641 Cas is an object related to CH Cyg and ο Cet, with accreting white dwarf as a secondary. If the companion is a subluminous object one may expect symbiotic phenomenon in this star.
