Title: Universal Relations between the Neutron Star M-R Relation and Equation of States of Dense Matter
Abstract: We developed an analytic method of inverting the TOV relations to high accuracy with the constructed Database: a semi-universal power-law relation between the central energy densities, pressures, sound speeds, chemical potentials and number densities of neutron stars, with the maximum mass and the radii of one or more fractional maximum mass points. Root-mean-square fitting accuracies, for EOSs without large first-order phase transitions, are typically 0.5% for all quantities at all mass points, and for EOS with first-order phase transitions, the method still works, although less accurately. We also developed a visualization software for mutual inversion of neutron star M-R curve and its underlying EOS based on this approach. In the seminar, I will talk about the background, advantages, applications of our method, and possible improvements in the future.
