Abstract

Inspiral dynamics of compact binaries: its applications

Gravitational waves are ripples in the fabric of space and time produced mainly by violent astrophysical events like the merger of two Black Holes.

There are several on-going and planned endeavors to realize Gravitational Wavw Astronomy by directly detecting these elusive waves: one of the key predictions of Einstein’s General Theory of Relativity.

Compact binaries, consisting of Black Holes and Neutron Stars, spiralling in due to the emission of gravitational radiation are the most promising sources to realize Gravitational Wave Astronomy.

And, the post-Newtonian approximation to General Relativity can be employed to describe, very accurately, the inspiral dynamics of compact binaries. I will describe briefly applications of the above approach that would be revelant for:

1. Analyzing the date from the operational and planned interferometric gravitational wave detectors like LIGO/VIRGO and LISA.
2. Validating the recent advances in Numerical Relativity involve merging black hole binaries.
3. The proposed Square Kilometre Array.
