Graduate Student Seminar with Chun Huang on Into the Interior of a Neutron Star

In this talk, I will discuss recent progress in exploring the interior of neutron stars through observation and theoretical modeling. The current constraints on the possibilities of its composition will be demonstrated. Following that, I will discuss our recent work on investigating this by constraining the fundamental physics parameters in neutron stars using a real physics model (as opposed to agnostic ones). Several exciting properties like particle fraction, speed of sound, etc. will first-time be constrained under this model framework. The future observation mission power that comes from next generation X-ray telescopes like eXTP and STROBE-X has been explored. I will illustrate that many fundamental mysteries of Neutron stars, like the hyperon puzzle, could be tested and eventually determined or excluded by future observations. Hopefully, this will convince you that in the near future (10–20 years), we can really understand what neutron star is made of through the synergy of Gravitational wave detection and X-ray observation.
