J0453+1559: a neutron star-white dwarf binary from a thermonuclear electron-capture supernova?

12 Nov 2019 Tauris Thomas M. Aarhus Uni. Janka H. -Thomas MPA, Garching

The compact binary radio pulsar system J0453+1559 (Martinez et al. 2015) consists of a recycled pulsar as primary component of $1.559(5)\,M_\odot$ and an unseen companion star of $1.174(4)\,M_\odot$. Because of the relatively large orbital eccentricity of $e = 0.1125$, it was argued that the companion is a neutron star, making it the neutron star with the lowest accurately determined mass to date...
