Sirius is actually a binary star: Sirius A, which is a white main-sequence star and which is accompanied by Sirius B, a white dwarf.Around 100 years ago it was suggested that Sirius may belong to the Ursa Major moving group.

No. Sirius is actually two stars. The main body, Sirius A, is a fairly large star, larger than the sun, but it is nowhere near the size of a supergiant. Sirius B is a white dwarf, a small, dense remnant of a star that is, int his case, slightly smaller than Earth.

All of the radio models share the same battery life.
