The possible companions of young radio pulsars.
PORTEGIES ZWART S.F. and YUNGELSON L.R.
Abstract (from CDS):
We discuss the formation of pulsars with massive companions in eccentric orbits. We demonstrate that the probability for a non-recycled radio pulsar to have a white dwarf as a companion is comparable to that of having an old neutron star as a companion. Special emphasis is given to PSR B1820-11 and PSR B2303+46. Based on population synthesis calculations we argue that PSR B1820-11 and PSR B2303+46 could very well be accompanied by white dwarfs with mass ≳1.1M☉. For PSR B1820-11, however, we cannot exclude the possibility that its companion is a main-sequence star with a mass between ∼0.7M☉ and ∼5M☉.
