Breakdown:
Krait Phantom - 1

An unusual combination of a carbon star and a white dwarf. The white dwarf is of a rare spectral type DBZ; only 8 white dwarf stars of this type are currently known as of July 3303.

The DBZ class indicates this white dwarf has a stellar atmosphere composed mostly of helium, but also has unusual and unexpected heavy elements in the atmosphere. Since heavy elements are quickly pulled into the lower layers of the white dwarf by gravity, they must be supplied by an outside source. Scientists currently believe these DBZ stars are pulling in material from disks of previous planetary systems.

The carbon star is 128 solar radii in size and with a surface temperature of just 1661 kelvin. An alternative option for the DBZ star's odd spectrum may be in mass-loss from the carbon star; carbon is considered a heavy element in stellar dynamics.
