Small Stars In A Large Context: All Things White Dwarf By Don Winget Wortham Giant Screen Theatre Dubbed "impossible stars," white dwarfs are the simplest stars with the simplest surface chemical compositions known-yet are very mysterious. The McDonald Observatory leads in investigating white dwarfs along several avenues: telescope observations, theory, and most recently, the making of star-stuff using the most powerful X-ray source on Earth at Sandia National Laboratory. Dr. Don Winget, one of the world's leading experts on white dwarfs, will examine the how studies of these stars can shed light on everything from the age of the Universe to the understanding of dark matter and dark energy. This lecture is sponsored by the University of Texas at Austin McDonald Observatory in celebration of their 75th anniversary in 2014.
