Thermal Emission from Binary Millisecond Pulsar Stars (MSPs)‎

Abstract EN

Pulsar stars divided into two types depending on the periods of rotation, normal emission Pulsar and Millisecond pulsars (MSPs).

In this paper, the effect of the strong magnetic field on the thermal emission in Millisecond pulsar stars is concentrated.

Also the luminosity spin down (Lsp) are calculated depends on the periods (P), and Period derivative (•P) for sample stars which were adopted.

The relation between internal and surface magnetic field is illustrated.

The model that which adopted is Hallo Cone Model (HCM)).

The total magnetic dipole radiation power (heating power Wh) of all super fluid neutrons in MSPs stars is calculated.

For sample stars of MSPs, the value of transition period (Ptr) was determined by depending on the some properties of pulsar star.

The results indicated that heating power of our model (A) would be larger than the model (B) that's due to the huge value of the moment of inertia (I).

Also the results showed that the maximum surface luminosity of stars occurs at the values of Magnetic field ≥ 5.5 1012 Gauss.
