Black Dwarf Star Death Physical Characteristics • Diameter • Size of the Earth • Chemical Composition • Depleted carbon • Surface Temperature • At most 5 K • Luminosity • Emit very little radiation • Only detectable through gravitational influence Examples • None known • Universe is too young to create black dwarfs • Derived from 2 star types – Low-Mass Stars – Medium-Mass Stars • Will replace white dwarfs Existence • Existence is only hypothetical • Formation • 1 quadrillion years to form • Oldest Known Black Dwarf • None detected yet • Stage Of Stellar Evolution • End of star life • Future • Unknown Discovery • None discovered • Reasons – Slowing black dwarf formation • Dark Matter • Proton Decay – White dwarfs slow cooling rate • Need to cool to cosmic background radiation levels • Likely to happen after trillions of years Black Dwarf Facts • Universe is too young to create black dwarfs • White dwarf decay length is unknown • No proof of existence • Matter would be extremely dense • Thought to be the final product of our Sun Black Dwarf Video https://www.youtube.com/watch?v=6glP6Rw iEts Literature Cited • http://en,wikipedia.org/wiki/black_dwarf • http://www.solarviews.com/eng/blackdwarf.ht m • http://nineplanets.org/Black_Dwarf.htm • Our Universe • Star Evolution
