JOY 1 | Aa,Ab: The primary is omi Cet = VZ Cet = 68 Cet = Mira , prototype of | |
the Mira-type variables. "Orbits" have been computed for the visual | ||
pair, but are most likely false. B has in the past been identified as a | ||
Cepheid, VZ Cet; however, it appears that the component seen as | ||
variable is the Joy component, recently determined to be a White Dwarf. | Skl2010 | |
Recent papers (in particular 1995 PhD thesis by Harold L. Chambers II) | ||
suggest that the visible companion is not the star itself, but the | ||
accretion disc around it (material captured from Mira's stellar wind). | ||
Rapid fluctuations of brightness are described by Warner (1972 MNRAS | ||
159, 95). | ||
See Baize & Petit (1989) catalog of doubles with variable component. | Baz1989d | |
Aa,Ab: Pair seen but not measured. | Cou1958c | |
