Department News and Colloquium

Physics & Astronomy Colloquium at CSU Long Beach

Gravitational Waves

from Vibrating Neutron Stars

Prof. Prashanth Jaikumar

Physics & Astronomy Department

California State University Long Beach

Monday, October 17, 2016

11:15am in PH2-126

The recent detection of Gravitational Waves from merging Black Holes opened a new window of astrophysical observation for Neutron Stars as well. While merging Neutron Stars are the main target of opportunity, vibrating isolated Neutron Stars can also be studied with next generation interferometers. We describe the spectrum of non-radial oscillation modes of single Neutron Stars and Quark Stars within various models of dense matter. Differences between these two configurations arise for the $l$=2 spheroidal high-frequency (f, p) modes already in Newtonian gravity. For a star with a crust, the shear-modified p-modes provide a discriminating feature between Neutron and Quark Stars, which can constrain the equation of state of extremely dense matter.

All Physics students & faculty should attend!

Colloquia are scheduled to start Mondays at 11:15am sharp in Peterson Hall 2, Room 126 (PH2-126). Refreshments are served from 10:45am to 11:05am in Room HSCI-224 (next to the department office) and everyone is invited to mingle with faculty and students!
