Title: Exploring exotic interior of Neutron star through Transport Phenomena

Speaker: Prof. Sreemoyee Sarkar, CEBS, Mumbai

Abstract: Neutron stars are dense remnants of collapsed massive stars and can be thought of as a wonderful astrophysical laboratory for studying extremely dense matter. Our present understanding suggests that compact stars are composed of well-defined layers and expected to have supranuclear densities in their cores. Naturally, at this incredibly high density, matter which starts out in the original star wouldn't survive in their original form. So, there is possibility of existence of different states of matter. To analyze the impact of phases in different layers requires constraints on the equation of state as well as observational constraints on its transport properties. Dissipative processes, such as shear and bulk viscosities govern damping of toroidal modes of neutron stars and thermal conductivity of a young neutron star determine cooling. This talk will focus on the origin, evolution and importance of different transport coefficients to probe different phases of matter inside these compact stars.
