Recent scientific studies are challenging established theories regarding the physical properties and appearance of white dwarf stars. Research from the University of Warwick indicates that these stars can exhibit a wider range of colors than previously assumed, such as green, pink, and violet, due to unique atmospheric compositions and the absorption of rocky debris from former planetary systems. 

Further research led by scientists from the Indian Institute of Science suggests that intense internal magnetic fields might allow certain white dwarfs to exceed the Chandrasekhar limit, potentially reaching approximately 2.4 solar masses instead of the traditional 1.4 solar mass limit. These findings collectively question standard models of blackbody radiation and stellar mass limits.
