I-Q relation for rapidly rotating neutron stars
Sayan Chakrabarti, Térence Delsate, Norman Gürlebeck +1
We consider a universal relation between moment of inertia and quadrupole moment of arbitrarily fast rotating neutron stars. Recent studies suggest that this relation breaks down f…
Effective action and linear response of compact objects in Newtonian gravity
Sayan Chakrabarti, Térence Delsate, Jan Steinhoff
We apply an effective field theory method for the gravitational interaction of compact stars, developed within the context of general relativity, to Newtonian gravity. In this effe…
New perspectives on neutron star and black hole spectroscopy and dynamic tides
Sayan Chakrabarti, Térence Delsate, Jan Steinhoff
We elaborate on a powerful tidal interaction formalism where the multipole dynamics is kept generic and encoded in a linear response function. This response function is the gravita…
Recent progress in spin calculations in the post-Newtonian framework and applications
Johannes Hartung, Jan Steinhoff, Gerhard Schäfer
Recently we derived the next-to-next-to-leading order post-Newtonian Hamiltonians at spin-orbit and spin(1)-spin(2) level for a binary system of compact objects. In this talk the d…
Influence of internal structure on the motion of test bodies in extreme mass ratio situations (MG13)
Jan Steinhoff, Dirk Puetzfeld
We present some recent results on the motion of test bodies with internal structure in General Relativity. On the basis of a multipolar approximation scheme, we study the motion of…
Next-to-next-to-leading order post-Newtonian linear-in-spin binary Hamiltonians
Johannes Hartung, Jan Steinhoff, Gerhard Schäfer
The next-to-next-to-leading order post-Newtonian spin-orbit and spin(1)-spin(2) Hamiltonians for binary compact objects in general relativity are derived. The Arnowitt-Deser-Misner…
Canonical Angles In A Compact Binary Star System With Spinning Components: Approximative Solution Through Next-To-Leading-Order Spin-Orbit Interaction for Circular Orbits
Manuel Tessmer, Jan Steinhoff, Gerhard Schäfer
This publication will deal with an explicit determination of the time evolution of the spin orientation axes and the evolution of the orbital phase in the case of circular orbits u…
