#### Charge distribution in neutron stars.

(2017)

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 ...

#### Searching for exoplanets using the transit method.

(2017)

We present a study designed to detect transiting exoplanets in Kepler
light curve data. We developed an exoplanet detection algorithm based on
modelling transit light curves and fitting the models to light curve data ...

#### Differential equations for relativistic radiating stars.

(2013)

We consider radiating spherical stars in general relativity when they are conformally
flat, geodesic with shear, and accelerating, expanding and shearing. We study the
junction conditions relating the pressure to the ...

#### Exact models of compact stars with equations of state.

(2013)

We study exact solutions to the Einstein-Maxwell system of equations and relate them to compact
objects. It is well known that there are substantial analytic difficulties in the modelling of
self-gravitating, static fluid ...

#### New realistic solutions for charged matter with an equation of state.

The purpose of this thesis is to provide new exact solutions to the Einstein-Maxwell
system which are physically reasonable. We assume that the spacetime is static and
spherically symmetric with a charged anisotropic ...

#### Relativistic radiating stars with generalised atmospheres.

(2010)

In this dissertation we construct radiating models for dense compact stars in relativistic
astrophysics. We first utilise the standard Santos (1985) junction condition to
model Euclidean stars. By making use of the ...

#### Thermal evolution of radiation spheres undergoing dissipative gravitational collapse.

(2014)

In this study we investigate the physics of a relativistic radiating star undergoing dissipative
collapse in the form of a radial heat flux. Our treatment clearly demonstrates
how the presence of shear affects the collapse ...

#### On the physical viability of horizon-free collapse.

(2014)

The so-called Cosmic Censorship Conjecture has drawn widespread attention amongst
astrophysicists and particle physicists. In particular, the end-state of gravitational collapse
of a bounded matter distribution is a ...

#### Shear-free models for relativistic fluids with heat flow and pressure isotropy.

(2014)

We model the interior dynamics of a relativistic radiating
fuid in a nonstatic spher-
ically symmetric spacetime. The matter distribution takes the form of an imperfect
fuid with a nonvanishing radially directed heat ...
