Novae like this produced dust grains found in meteorites. Studies of their composition could tell us the temperatures at which they exploded. NASA/CXC/RIKEN/D.Takei et al; Optical: NASA/STScI; Radio: NRAO/VLA -

Tiny dust particles found in meteorites show evidence of having been formed long before the Solar System. Testing suggests they may have formed in exploding stars that long predate the Sun, and their composition could tell us the temperatures of those explosions.
