Discovery of binary star system could make waves in physics

International team including UAlberta physicist discovers double star that could prove a prediction of Einstein's theory of gravity. In this illustration of an AM CvN binary star system, a small, heavy white dwarf star pulls material from its larger but less dense companion star. This week, astronomers announced the first observation of one of these rare double-star systems in its developing stages. (Image: NASA/CXC/M. Weiss) An international group of space researchers including a University of Alberta physicist has made a discovery that could have a ripple effect on the science of gravity. This week, astronomers announced the first observation of a type of double-star system (known as AM CVn) in its developing stages. Many researchers expect that these systems may eventually provide proof of a major prediction of Einstein's theory of gravity (also known as the theory of general relativity).
