This collapsed star is turning into an gigantic diamond before our eyes

These findings are limited and require further investigation before we can say for sure. It'd certainly be interesting if our initial estimates were off by several orders of magnitude.

Motivated by the possibility that a cooling delay caused by crystallization can be directly detected for this white dwarf we employ a variety of methods to constrain the age of the system; however, our empirical age anomaly of +3.1±1.9 Gyr is ultimately too imprecise to reach statistical significance, preventing us from making strong constraints to models of white dwarf crystallization.
