Minimum Accretion Rate for Millisecond Pulsar Formation in Binary System
Yuanyue Pan, Chengmin Zhang, Na Wang
TL;DR
This paper identifies a minimum accretion rate necessary for binary pulsars to evolve into millisecond pulsars, based on observational data and theoretical analysis.
Contribution
It establishes a threshold accretion rate for millisecond pulsar formation, combining observational evidence with theoretical reasoning.
Findings
Minimum accretion rate for millisecond pulsar formation identified
Binary pulsars below this rate do not become millisecond pulsars
Analysis based on magnetic field versus spin period diagram
Abstract
186 binary pulsars are shown in the magnetic field versus spin period (B-P) dia- gram, and their relations to the millisecond pulsars can be clearly seen. We declaim a minimum accretion rate for the millisecond pulsar formation both from the observation and theory. If the accretion rate is lower than the minimum accretion rate, the pulsar in binary system will not become a millisecond pulsar after the evolution.
