12. Tests of general relativity and neutron star mass measurements from timing of radio pulsars

Dr P Freire (Max Planck Institute - Bonn)

05/09/2016, 16:30

In this lecture, I will introduce some basic concepts related to neutron stars, radio pulsars and their evolution. I then describe in detail timing of radio pulsars in binary systems, using the results from the first binary pulsar, PSR B1913+16, as an important example. First, I describe how pulsar timing of this system was used to determine the masses of the components, and then I describe...

16. General relativity computations with SageManifolds

E. Gourgoulhon (Observatoire de Paris)

06/09/2016, 16:30

SageManifolds [1] is an extension of the Python-based modern computer algebra system SageMath [2] towards differential geometry and tensor calculus. We shall use it to perform computations and draw figures regarding neutron star and black hole spacetimes. The School participants are encouraged to install the free software SageMath on their computer prior to the school or to open a free account...

17. Gravitational wave source modeling

Dr I. Jones (University of Southampton)

07/09/2016, 09:00

Gravitational Wave source Modelling 1: Basic formalism In this lecture I will present the so-called quadrupole formalism for describing the gravitational wave emission from a neutron star. Within this formalism, General Relativity is treated as a correction to Newtonian physics. I will sketch out the key formulae, and show how they lead to some well known results for the gravitational...

15. Analytical Relativity Modelling of Coalescing Compact Binaries

Dr A. Le Tiec (Observatoire de Paris)

07/09/2016, 11:00

In this lecture, I will give an introduction to the analytical approximation methods that are used to model the orbital dynamics and gravitational-wave emission of binary systems of compact objects (neutrons stars and black holes), namely the post-Newtonian approximation, black hole perturbation theory and the gravitational self-force formalism, and the effective one-body model. The key ideas...

18. Effect of the Magnetic Field on the Dense Matter EoS

Dr V. Dexheimer (Kent State University)

07/09/2016, 14:30

I will present a lecture about the modifications introduced in the EOS of dense by the presence of strong magnetic fields. We know that magnetic fields of up to 10^15 G have been measured on the surface of neutron stars and a field of 10^16 have been measured somewhere inside a neutron star. We speculate further that magnetic fields of more than 10^18 Gauss can exist in the center of massive...

Gravitational Wave source Modelling 2: Applications

In this lecture I will apply the basic formalism described in my previous lecture to the gravitational wave emission from neutron stars in various contexts. In particular I will discuss rotating non-axisymmetric neutron stars, making the connection between neutron star microphysics and possible gravitational wave amplitudes explicit.

Dr E. Kantor (Ioffe Physical-Technical Institute of the Russian Academy of Sciences, St.-Petersburg)

08/09/2016, 16:30

In this lecture I will review the main features of bulk and shear viscosities in application to neutron stars. Starting with the discussion of the main processes contributing to both viscosities in superdense matter I will proceed to the effects of superfluidity. I will show how the baryon superfluidity affects the functional dependences and values of the coefficients and, moreover, how it...

24. Introduction to NS Oscillations & Instabilities

Dr K. Glampedakis (University of Tuebingen)

09/09/2016, 09:00

This lecture provides a detailed discussion of gravitational wave-driven instabilities in neutron stars and highlights their implications for the photon and gravitational wave astronomy of these objects. The emphasis is given on the analysis of the (most promising) r-mode and f-mode instabilities: we discuss the, occasionaly exotic, physics that determines their instability “windows”,...

33. Selected Poster:The liquid-gas phase transition within the temperature-dependent DD-NLD mode

Sofija Antic (GSI)

09/09/2016, 11:00

The equation of state (EOS) of dense matter is essential for modeling compact astrophysical objects and sets the conditions for the creation of chemical elements in the universe. To provide it, we use the generalized DD-NLD relativistic mean-?field model (RMF) with density-dependent nucleon-meson couplings and higher-order derivative couplings between nucleons and mesons. The model is extended...

35. Selected Poster: Thermodynamic Geodesics of a Supermassive Reissner-Nordström Black Hole

Christine Farrugia

09/09/2016, 11:30

Abstract: Starting from a Geometrothermodynamics metric for the space of thermodynamic equilibrium states in the mass representation, numerical techniques are used to analyse the thermodynamic geodesics of a supermassive Reissner-Nordström black hole in isolation. Appropriate constraints are obtained by taking into account the processes of Hawking radiation and Schwinger pair-production. It...

26. Bulk & Shear Viscosities in Dense Quark Matter

Dr A. Schmitt (University of Southampton)

09/09/2016, 16:30

I will review and explain calculations of bulk and shear
viscosity in various phases of dense quark matter, in unpaired quark
matter as well as in color-superconducting phases such as the
color-flavor locked phase. I will discuss and interpret the results,
which are relevant for instance for the r-mode instability in rotating
stars and thus are measurable, at least indirectly,...
