White Dwarf Transforms into Massive Diamond in Space

Astrophysicists have found a white dwarf in the process of crystallizing, which will help them understand how and when this phenomenon occurs. The white dwarf is in a system with other main-sequence stars, making it easier to determine its age. The researchers estimate its age to be 7.3 billion years, but they say it could be an underestimation. The white dwarf is the first confirmed crystallizing white dwarf in a Sirius-like system, and its location in a system with other stars will make it easier to study white dwarf crystallization.
