WD J2147–4035
WD J2147–4035 (DES J214756.46-403529.3) is a very cold white dwarf with a temperature of about 3,050 Kelvin (2780 °C; 5030 °F). It also shows signs of pollution with planetary debris. WD J2147–4035 was first identified from Gaia (spacecraft), Gaia data as a white dwarf candidate in 2019. In 2021 it was pointed out as an unusual faint white dwarf in the solar neighbourhood. The researchers found it could be extremely old (about 10 Gyrs). In 2022 results from observations with X-shooter on the Very Large Telescope were published. The object was identified as a white dwarf, likely with a helium-dominated atmosphere. The researchers also detected metal pollution in the form of sodium, lithium, potassium and possibly carbon. The lithium line shows Zeeman effect, Zeeman splitting, which indicates that WD J2147–4035 is a magnetic white dwarf. The researchers measure a magnetic field strength of 0.55 ±0.03 Gauss (unit), Megagauss. The magnetism can lead to inhomogeneous b ...
