Gravitational Radiation from Inspiraling Binaries: A Review

In summary, the conversation discusses the Bekenstein-Hawking entropy and the quasinormal mode in relation to black holes. The Bekenstein-Hawking entropy is a measure of the entropy of a black hole, while the quasinormal mode relates to resonance modes of a black hole. The holographic principle is also mentioned, which links the entropy of a black hole to its surface area. The conversation also refers to a logarithmic correction for the Bekenstein-Hawking entropy, which can be found on a website provided in the conversation.

of course! should have thought of that,
thanks

this maybe of interest.

What is the Bekenstein-Hawking entropy? what is "quasinormal mode"? $A/4$? :confused:

I found a logarithmic correction for the Bekenstein-Hawking entropy thing on this site: http://www.iop.org/EJ/abstract/0264-9381/18/15/303\

The Beckenstein-Hawking entropy essentially says that the entropy of a black hole is proportional to its horizon area (the A in A/4; note that is in natural units -- there is a G, hbar, and k floating in it). This was recently generalized by Bousso to become the holographic principle, which states that the number of degrees of freedom (information content) in a volume of space is also proportional to the surface area of a bounding "light sheet". The holographic principle shows promising links between relativity and field theory, e.g. the AdS/CFT correspondence.

The quasinormal mode has to do with resonance modes of a black hole, if I recall correctly. Dryer has derived an interesting result for this, which involves a factor of ln(3). I can't remember specifics (I saw him speak about it at a conference last summer), but if you look up his other papers on arxiv, you'll find the appropriate references.
 

1. What is gravitational radiation?

Gravitational radiation, also known as gravitational waves, is a form of energy that is emitted by objects with mass as they accelerate or move through space. It is a prediction of Einstein's theory of general relativity and has been observed indirectly through its effects on objects in space.

2. What are inspiraling binaries?

Inspiraling binaries are a type of binary system in which two objects, such as two stars or a star and a black hole, are in orbit around each other and gradually spiral closer together due to the emission of gravitational radiation. This phenomenon is also known as a gravitational wave source.

3. How is gravitational radiation from inspiraling binaries detected?

Gravitational radiation from inspiraling binaries is detected using specialized instruments called interferometers, which measure the extremely small changes in distance caused by passing gravitational waves. The most well-known interferometer is the Laser Interferometer Gravitational-Wave Observatory (LIGO).

4. Why is the study of gravitational radiation from inspiraling binaries important?

Studying gravitational radiation from inspiraling binaries allows us to test the predictions of Einstein's theory of general relativity and gain a better understanding of the nature of gravity. It also opens up new avenues for observing and studying the universe, as gravitational waves can provide information about objects and events that are not detectable through other means.

5. What are the potential applications of gravitational radiation from inspiraling binaries?

Gravitational radiation from inspiraling binaries has the potential to be used in a variety of fields, including astrophysics, cosmology, and fundamental physics. It can be used to study the behavior of objects in extreme environments, such as black holes and neutron stars, and to probe the structure and evolution of the universe. It may also have practical applications, such as improving our ability to navigate in space.
