[SEMINARI] [SEMINAR] Superfluid Magnetars and QPO spectrum. Andrea Passamonti

[Enric Marco]

Title: Superfluid Magnetars and QPO spectrum.

  Abstract:

The analysis of Quasi Periodic Oscillations (QPOs) in Magnetars provided 
the first application of
Asteroseismology in neutron stars. These oscillations are likely 
identified with magneto-elastic
waves which originate from the giant flares. Recent cooling calculations 
show that heat generated
by magnetic field decay does not prevent the superfluid transition of 
the magnetar's core.
This means that realistic models of magnetars should include 
superfluid/superconducting
constituents in order to extract information from QPO observations. In 
this talk, I report our
results on the oscillation spectrum of superfluid and magnetised neutron 
stars and the implications
of superfluid physics on the QPOs.
