Shapiro delay measurement of a 2 solar mass neutron star

We will discuss techniques used in the mass measurements of distant astrophysical objects. In particular we will focus on binary system with pulsar PSR J1614-2230. The large, precisely measured mass of this object has been a source of intense discussion on constraining power of such observation, in particular on the possibility of appearance of exotic phases of matter in cores of neutron stars.
