Triple millisecond pulsar laboratory challenges theory

more »

(Phys.org) —Millisecond pulsars are old neutron stars, which rotate several hundred times per second. They are often found in binary systems and their existence can be explained by mass transfer from a companion star. The recent discovery of a millisecond pulsar orbited by two white dwarfs (Ransom et al., 2014) comes as a surprise and challenges current theories of their formation. The astrophysicists Ed van den Heuvel of the University of Amsterdam and Thomas Tauris from Bonn have developed a semi-analytical model which can resolve the intriguing formation of this unique triple system.
