PSR B1913+16 (or J1915+1606) is a binary pulsar, or a pulsar in a binary star system. A binary pulsar consists of two stars orbiting around each other (around a common center of mass based on the two stars).
This particular binary pulsar, PSR B1913+16 was discovered by Russell Alan Hulse and Joseph Hooton Taylor, Jr., of Princeton University. They were later awarded the 1993 Nobel Prize in Physics based on a claim in the abstract of their paper that this binary pulsar confirms the Theory of General Relativity due to its loss in energy over time, which Hulse and Taylor attributed to the radiation of gravitational waves under the Theory of General Relativity.
