Description
This study investigates the impacts of both finite temperature and strong magnetic field on Anisotropic Deformed Magnetized White Dwarfs within the parameterized γ-metric formalism. We have considered a relativistic free Fermi gas of electrons embedded in strong quantizing magnetic fields and at finite temperatures. Due to the anisotropy in the pressures parallel and perpendicular to the direction of the magnetic field, these magnetized white dwarfs become oblate spheroids. This deformation is accounted in the presence of a deformed Schwarzschild metric known as the γ-metric. Stable super-Chandrasekhar masses (> 5M⊙) are found. We also see that increasing central magnetic field leads to decreased masses and increased equatorial radii, with maximum mass occurring at higher central densities. Conversely, increasing the temperature leads to increase in both mass and radius, counteracting magnetic field effects by stiffening the Equation of State (EoS) and decreasing the anisotropy. This work highlights the interplay between temperature and magnetic fields, impacting the compactness and anisotropy of magnetized hot white dwarfs.
