Using the expression of the quadrupole and octapole radiation power , the multipole radiation power of a special binary star , psr1913 + 16 , are estimated . the results show that its whole power of quadrupole radiation is , which is coincident with the observed results , and that the expected whole power of octapole radiation is 本文用所得到的引力的四極和八極輻射的功率表達(dá)式計(jì)算了psr1913 + 16脈沖雙星的多極引力輻射,其四極輻射的總功率數(shù)量級為,與已經(jīng)觀測到的間接結(jié)果是一致的。
百科解釋
Multipole radiation is a theoretical framework for the description of electromagnetic or gravitational radiation from time-dependent distributions of distant sources. These tools are applied to physical phenomena which occur at a variety of length scales - from gravitational waves due to galaxy collisions to gamma radiation resulting from nuclear decay.
