Modelos para el estudio de la corteza de las estrellas de neutrones.

M. Ángeles Pérez García

Resumen


In the exterior shells or crust of neutron stars and in supernova matter it is believed that non-uniform structures exist. In this type of astronomical objects the relevant densities in the crust range from one half that of nuclear saturation density to several orders of magnitude smaller. The aggregates of nuclear matter in the crust arise due to the competition of the short ranged nuclear force and long range electromagnetic interaction. These clusters have typical sizes of dozens of femtometers and form different spatial shapes. Its importance is crucial in the supernova core collapse dynamics since these clusters can efficiently scatter escaping neutrinos vastly produced in a core collapse event allowing for substantial energy deposition in the medium. This could help to solve the problem of understanding the mechanism of the explosions observed.
