WD 2359-434 (Gliese 915, LHS 1005, L 362-81) is a nearby degenerate star (white dwarf) of spectral class DAP5.8, the single known component of the system, located in the constellation Phoenix, the nearest star in this constellation.
Distance.
WD 2359-434, probably, is the 11th closest white dwarf, or, possibly, 9th, 10th, or 12th (see Gliese 293, GJ 1087 and Gliese 518). Currently, the most
WD 2359-434 is composed of very dense degenerate matter, its mean density is 1,300,000 g·cm, i.e. mass of one cubic millimetre of WD 2359-434 matter is 1.3 kg.
Main sequence progenitor properties.
As all degenerate stars, WD 2359-434 previously existed initially as main-sequence star and then as giant star, until all the thermonuclear fuel was exhausted, after which WD 2359-434 lost most of its mass. According to the 2010 thesis for the degree of Doctor of Science, using Wood
