Polar kicks and the spin period - eccentricity relation in double neutron stars
B. Willems, J. Andrews, V. Kalogera +1
We present results of a population synthesis study aimed at examining the role of spin-kick alignment in producing a correlation between the spin period of the first-born neutron s…
Interacting Binaries with Eccentric Orbits. Secular Orbital Evolution Due To Conservative Mass Transfer
J. F. Sepinsky, B. Willems, V. Kalogera +1
We investigate the secular evolution of the orbital semi-major axis and eccentricity due to mass transfer in eccentric binaries, assuming conservation of total system mass and orbi…
Mass transfer and the period decrease in RXJ0806.3+1527
B. Willems, V. Kalogera
We examine the nature of RXJ0806.3+1527 and show that it is possible to reconcile the observed period decrease and X-ray luminosity with the transfer of mass between two white dwar…
The Formation of the Most Relativistic Pulsar PSR J0737-3039
B. Willems, V. Kalogera, M. Henninger
We present an updated set of constraints for the progenitor of PSR J0737-3039 and for the natal kicks imparted to pulsar B taking into account both the evolutionary and kinematic h…
Pulsar Kicks and Spin Tilts in the Close Double Neutron Stars PSR J0737-3039, PSR B1534+12 and PSR B1913+16
B. Willems, V. Kalogera, M. Henninger
In view of the recent measurement of the scintillation velocity for PSR J0737-3039, we examine the complete set of constraints imposed on the pulsar B natal kicks (magnitude and or…
Constraints on the Formation of PSR J0737-3039: the most probable isotropic kick magnitude
B. Willems, V. Kalogera
A strongly relativistic binary pulsar has been recently discovered with the 64m Parkes telescope (Burgay et al. 2003). Here we use the measured properties of this binary (masses an…
