【 摘 要 】

The junction conditions for a magnetohydrodynamic fluid sphere undergoing dissipative gravitational collapse in the form of a radial heat flux with shear are obtained. These conditions extend particular results of earlier treatments. We demonstrate that the pressure is proportional to the magnitude of the heat flux as is the case in shear-free models. However in our case the gravitational potentials must be solutions of the Einstein–Maxwell system of equations. The mass function 𝑚(𝑣) is increased by a factor related to the charge 𝑄 of the radiating star. Physical quantities relating to the local conservation of momentum and surface redshift are obtained.
