Abstract
In previous studies, people have shown that compact stars, like the neutron stars
and quark stars, can hold a lot of charge during their formation resulting in a large
mass and radius. It was also argued that when the charges leave the system due
to repulsion from the self created field, these might render a secondary collapse
to a charged black hole. In the present work, we have taken a particular type of
charge distribution, with varying parameters, such that changing these parameters
mimic the situation when the charge particles leaving the system. We have made
a systematic study of each stage of the charge distributions. Our results reveal that
when the charge distribution deviates slightly from the scenario where the charge
density is proportional to the mass density, then the system is no longer able to
retain the large mass and radius, and quickly attains a lower mass and radius.
