Abstract

Neutron stars are some of the most extreme objects in Nature. Their
large masses (typically around 1.4 times that of the mass) combined
with their small radii (typically around 12 km) result in interior
densities that can exceed nuclear saturation density, above which
exotic states of matter can arise. Moreover, neutron stars are, next
to black holes, the strongest gravitational field sources known. These
properties make neutron stars outstanding laboratories to study both
matter and gravity in situations out of reach in terrestrial and Solar
System experiments. In this webinar, I will discuss how recent neutron
star observations are allowing us Einstein’s theory of general
relativity and modifications thereof.
