| dc.description.abstract | In this research we investigate the shear-free, non-viscous perfect fluid model describing stellar object that emits radiation that leads to dissipation. We study matching of the interior metric with the exterior outgoing Vaidya metric via junction conditions. We also impose regularity and energy conditions in order for the model to be physically realistic. We find solution to main Einstein field equations, analyze and emphasize the features of the solution, specifically the impact of dissipation of the density 𝜌, pressure 𝑝 and mass 𝑚 functions, and present the resulted analysis in plots. We compare obtained solution to the conventional OSD collapse model and to solutions found in previous works, and investigate the prospects of the implementation of obtained results on future research in modified GR. | en_US |
