"Constraints on the braneworld from compact stars"
Dr. Daryel Manreza, ICN-UNAM
According to the braneworld idea, ordinary matter is confined on a
three-dimensional space (brane) that is embedded in a higher-dimensional
space-time where gravity propagates. In this work, after reviewing the
limits coming from general relativity, finiteness of pressure and causality
on the brane, we derive observational constraints on the braneworld
parameters from the existence of stable compact stars. The analysis is
carried out by solving numerically the brane-modified
Tolman\u2013Oppenheimer\u2013Volkoff equations, using different representative
equations of state to describe matter in the star interior. The cases of
normal dense matter, pure quark matter and hybrid matter are considered.
