scope note
Not to be confused with "Double-mode variable stars."
Some of the binary stars show additional period that this ~33 times longer than the orbital period and this group is called DPVs. Most of these systems are also showing eclipses, but that's not required. DPVs studied in detail show circumprimary discs. Note that the name seems general, but refers to only a specific group of binary stars. --
