Mass Distribution and Maximum Mass of Neutron Stars: Effects of Orbital Inclination Angle

Understand

Matter at ultra-high densities finds a physical realization inside neutron stars.

• One key property is their maximum mass, which has far-reaching implications for astrophysics and the equation of state of ultra dense matter.
• In this work, we employ Bayesian analysis to scrutinize the mass distribution and maximum mass threshold of galactic neutron stars.
• We compare two distinct models to assess the impact of assuming a uniform distribution for the most important quantity, the cosine of orbital inclination angles ($i$), which has been a common practice in previous analyses.
