Millisecond radio pulsars with known masses: parameter values and equation of state models

Understand

The recent fast growth of a population of millisecond pulsars with precisely measured mass provides an excellent opportunity to characterize these compact stars at an unprecedented level.

• This is because the stellar parameter values can be accurately computed for known mass and spin rate and an assumed equation of state (EoS) model.
• For each of the 16 such pulsars and for a set of EoS models from nucleonic, hyperonic, strange quark matter and hybrid classes, we numerically compute fast spinning stable stellar parameter values considering the full effect of general relativity.
• This first detailed catalogue of the computed parameter values of observed millisecond pulsars provides a testbed to probe the physics of compact stars, including their formation, evolution and EoS.
