Study the Distribution of Physical Properties on the P-Pdot Diagram for the Magnetar Stars

Sundus A. Abdullah Albakri, Marwa M. Yasseen


Abstract: Neutron stars are excellent subjects for unveiling more about the physical laws in nature. In this work some of the physical properties will be studied. Halo cone model will be considered within light cylinder limits. Neutron stars types like Milliseconds and Normal stars with Magnetar stars samples adopted in this work. Magnetic fields, luminosity, spin down and characteristic age will be calculated. P-Pdot diagram will be indicating the start of the trajectory a neutron star with follow along its life going to the lower right where a big population lies before fading out in the graveyard. The ages, magnetic field strength, the spin and its spin down rate are read from this diagram. The results showed that find that magnetar stars will be located at the top right of the diagram and the high-energy at high-derived long period. They are young stars compared to the stars of the millisecond second, which lies in the center of the diagram. This is also the region where we find those pulsars which are still associated with supernova remnants. These remnants fade and are not detectable anymore after a few hundred thousand years or so. Therefore, older pulsars with typically ages of a few million years can be found in the center of the diagram. If pulsars slow down further, conditions to create radio emission apparently cease, and the longest period known for Magnetar stars is just about 11 seconds.
