    BPM 37093 (V886 Centauri) is a variable white dwarf star of the DAV, or ZZ Ceti, type, with a hydrogen atmosphere and an unusually high mass of approximately 1.1 times the Sun's. It is 48 light-years (15 parsecs) from Earth in the constellation Centaurus and vibrates; these pulsations cause its luminosity to vary.

    en.wikipedia.org/wiki/Van_Maanen_2

    Like other white dwarfs, it is a very dense star: its mass has been estimated to be about 67% of the Sun's, [28] yet it has only 1% of the Sun's radius (1.23 times the Earth's radius) [8] [a] The outer atmosphere has a temperature of approximately 6,110 K, [28] which is relatively cool for a white dwarf. As all white dwarfs steadily radiate ...
