A white dwarf has no internal energy source. It shines only from residual heat. Therefore, the "hot" phase is a fleeting one in astronomical terms.
White dwarfs are the dense, cooling remnants of low- to medium-mass stars. While most are observed as relatively cool objects, a subset known as "hot white dwarfs" exhibit effective temperatures exceeding 80,000 K. This article explores the astrophysical significance of a specific hot white dwarf, catalogued in various surveys with the designation 137 (spectroscopically linked to SDSS J1240+6715 ), focusing on its unique atmospheric composition, extreme heat, and the insights it provides into late-stage stellar evolution. A review of available PDF -format scientific literature and data releases from the Sloan Digital Sky Survey (SDSS) and Gaia mission is provided. white dwarf 137 pdf hot
