Combined analysis of neutron star natal kicks using proper motions and parallax measurements for radio pulsars and Be X-ray binaries

Understand

Supernova explosion and the associated neutron star natal kicks are important events on a pathway of a binary to become a gravitational wave source, an X-ray binary or a millisecond radio pulsar.

• Weak natal kicks often lead to binary survival, while strong kicks frequently disrupt the binary.
• In this article, we aim to further constrain neutron star natal kicks in binaries.
• We explore binary population synthesis models by varying prescription for natal kick, remnant mass and mass accretion efficiency.
