A Well-Behaved Anisotropic Strange Star Model
Advances in Mathematical Physics, 2022 We obtain a new nonsingular exact model for compact stellar objects by using the Einstein field equations. The model is consistent with stellar star with anisotropic quark matter in the absence of electric field.

ANALYTICAL MODELS FOR QUARK STARS [PDF]
International Journal of Modern Physics D, 2007 We find two new classes of exact solutions to the Einstein–Maxwell system of equations. The matter content satisfies a linear equation of state consistent with quark matter; a particular form of one of the gravitational potentials is specified to generate solutions.

Modelling Neutron-Star Ocean Dynamics
Universe, 2023 We revisit the calculation of mode oscillations in the ocean of a rotating neutron star, which may be excited during thermonuclear X-ray bursts. Our present theoretical understanding of ocean modes relies heavily on the traditional approximation commonly employed in geophysics. The approximation elegantly decouples the radial and angular sectors of the

Modelling star cluster formation: Mergers
Monthly Notices of the Royal Astronomical Society, 2022 Abstract Star cluster formation in giant molecular clouds involves the local collapse of the cloud into small gas-rich subclusters, which can then subsequently collide and merge to build up the final star cluster(s). In this paper, we simulate collisions between these subclusters, using coupled smooth particle hydrodynamics for the gas ...

Intermediate‐Mass Stars: Updated Models [PDF]
The Astrophysical Journal, 1999 A new set of stellar models in the mass range 1.2 to 9 $M_{\odot}$ is presented. The adopted chemical compositions cover the typical galactic values, namely $0.0001 \le Z \le 0.02$ and $0.23 \le Y \le 0.28$. A comparison among the most recent compilations of similar stellar models is also discussed.
