Neutron Star Seismology: X-ray Burst and SGR Flare Oscillations

Anthony Piro (UCSB) - 14 Nov at 12:00 noon

Neutron star surface layers can house a rich assortment of non-radial modes. Observations and modeling of such modes are powerful probes for learning about their interiors. I will review the basics of shallow ocean waves in the context of neutron stars, including interesting complications such as rotation, a solid crust, and a strong magnetic field. This will be related to the burst oscillations seen from accreting neutron stars and the exciting, recently discovered giant flare oscillations from soft gamma-ray repeaters.

The seminar will be held in 544 Campbell Hall.
