Title: | Calculation of the thermodynamic properties of the spin polarized strange quark star in the presence of strong magnetic field | Authors: | Kayanikhoo, Fatemeh | Orientador: | Bordbar, Gholam Hossein | Keywords: | thermodynamic properties; strange quark star; strong magnetic field | Issue Date: | Jan-2012 | Place of publication or event: | Shiraz University | Abstract: | In this thesis, we investigated the strange quark matter (SQM) composed of the spin-up and spin-down; up, down and strange quarks at finite temperature in the presence of the strong magnetic field using the MIT bag model. We computed the total free energy of the spin polarized SQM at finite temperature in the presence of the strong magnetic field. We found that the free energy gets a minimum at a particular value of the spin polarization parameter showing a meta-stable state. The calculation shown that by increasing temperature, the equation of state of spin polarized SQM becomes stiffer. Also, using the general relativistic TOV equation, we studied the structure of the spin polarized strange quark star (SQS). We calculated the maximum mass and corresponding radius of spin polarized SQS at different temperatures and magnetic fields. We shown that the gravitational mass of spin polarized SQS rapidly increases by increasing the central energy density. We also indicated that the mass and the radius of the spin polarized SQS decreases by increasing both temperature and magnetic field. | Description: | Documentos apresentados no âmbito do reconhecimento de graus e diplomas estrangeiros | URI: | https://hdl.handle.net/10316/98847 | Rights: | openAccess |
