Using theoretical principles of fluid dynamics and general relativity, supplemented by numerical routines, this research will advance the understanding of nuclear physics at high density and its implications for compact star oscillations. The goal is to discover trends in the mode spectrum that can be used as gravitational wave fingerprints of the inner structure of neutron stars. In this project, the PI will calculate the non-radial oscillation modes of compact stars made in part or entirely of strange quark matter and will study their relevance to gravitational wave signatures. Results from this research will reduce the computational cost of searching for gravitational wave signals, refine existing models of nuclear physics, and train several graduate students from CSU Long Beach in the methods of scientific research. Integrating nuclear physics and astrophysics, the PI will use modern computational algorithms to estimate key parameters that affect the spectrum of gravitational waves emitted by neutron stars. This project is focused on improving the odds of detecting the gravitational waves from neutron stars by constructing accurate mathematical models of neutron stars and the signals they emit.

Unlike radio waves however, gravitational waves carry information about the interior of neutron stars, which will reveal new insight into nuclear physics at high density and temperature. There is broad consensus in the scientific community that LIGO will soon detect gravitational waves from numerous neutron stars in our Galaxy, which were first observed by radio pulses in the 1960s. The recent discovery of gravitational waves from Black Holes by the NSF-funded US-based LIGO observatories has captured the public imagination and opened a new observational window to our Cosmos, much like the discovery of the telescope did in Galileo's time.
