Neutron Stars

Neutron stars are extraordinary not only because they are the densest form of matter in the visible Universe but also because they can generate magnetic fields ten orders of magnitude larger than those currently constructed on Earth. The combination of extreme gravity with the enormous electromagnetic fields gives rise to spectacular phenomena like those observed on August 2017 with the merger of a binary neutron star system, an event that generated a gravitational wave signal, a short γ-ray burst, and a kilonova.

With the help of the COCAL code we solve the Einstein’s equations, Maxwell’s equations, and magnetohydrodynamic equations to construct models of isolated neutron/quark stars. These models are further evolved in order to study their stability properties, as well as their gravitational and electromagnetic signatures. Topics of interest include:

• Formulations
• Hydrodynamics
• Magnetohydrodynamics
• Equation of state
