The coolest white-dwarf: Surveys have been carried out to identify isolated white-dwarfs throughout the galaxy and its globular clusters
They have been found to span a range of temperatures, with a sharp lower limit of about 3000 K (i.e. many have been found at all temperatures from 10s of thousands of Kelvin down to 3000K, but none cooler). What does this observation reveal about the age of our galaxy?
