Assessing the complexity of orbital parameters after asymmetric kick in binary pulsars

Understand

The dynamical characterization of the Millisecond Pulsar (MSP) parameters is a key issue in understanding these systems.

• We present an analytical analysis of the orbital parameters of binary MSPs with long periods (Porb > 2 d) and circular (e < 0.1) orbits, produced by an asymmetric kick model imparted during the Accretion Induced Collapse (AIC) of white dwarfs process.
• It turns out that the distribution of orbits peaks up to P_orb;f < 90 d with strong circularization.
• Considering the different assumptions about the distribution of companions He stars 3M< Mcom < 5M, the binary will affect the setups of the balance condition of minimum energy.
