[igrav-steering] [igrav-announce] The problem on stationary states in self gravitational field

[Strunk, Amber D.]

This seems reasonable. I wonder if anyone has a template set of guidelines from other lists they are on.

We should probably post a set of guidelines and have that go out to to each subscriber when they subscribe.

Thanks for bringing this up Nicolas I was wondering the same thing. I agree maybe we can address this after the meeting itself.

Best,
Amber

Maybe on a longer timescale, we should also think of how we'd like to deal with this kind of posting... That person is registered to the mailing list whose current settings allow members to post directly => he followed the rules.

Cheers,

Nicolas

It is believed that according to the General Theory of Relativity (GR), systems with variable quadrupole or higher multipole moments can generate gravitational radiation. Under this assumption, the power of the corresponding gravitational radiation is proportional to the quadrupole mass distribution tensor of the radiating system /Qij/, and the constant /G/ (Newton's gravitational constant), that is included in this dependence, gives the order of magnitude of the radiation power.
The illegality of using this formula is not in the use of the quadrupole approximation, but in the calculation scheme. The system can emit only in certain quantum states, and this applies to any radiation, regardless of its nature. This is an axiom of quantum mechanics, as well as the existence of an elementary source of radiation having these states.
Consequently, the theoretical prediction of the spectrum of gravitational radiation requires evaluation of quantum states, transitions between which cause radiation.
