Astronomy undergraduates discover new type of star
University of Arizona astronomy undergraduates have discovered a new class of star that thrills astronomers who specialize in a relatively new field called "asteroseismology."
Astronomers worldwide will collaborate in continuous observations of one of these newly found stars for several weeks in May 2003.
