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. |
