A new approach to gravitational-wave detection

Новый подход к детект ированию гравитацио нных волн

Il Nuovo Cimento B (1971-1996)

Summary

If one calculates the rates of two clocks in the field of a gravitational wave in the linear approximation, one gets different results in the TT-gauge and the Fermi normal coordinate system. Care should, therefore, be given to use the TT-gauge to make predictions to be compared directly with experimental data.

Riassunto

Se si calcolano i ritmi di due orologi nel campo di un’onda gravitazionale, nell’approssimazione lineare, si ottengono risultati diversi a seconda che si usi la TT-gauge o il sistema di coordinate normali di Fermi, per cui bisogna usare cautela nella scelta del sistema di riferimento quando si vogliono confrontare i risultati teorici coi dati sperimentali.

Резюме

Если провести вычисл ения скорости хода двух часов в поле гравитационной волн ы в линейном приближе нии, то получаются различны е результаты в TT-калибро вке и в системе нормал ьных координат ферми. В свя зи с этим необходимо проя влять особое внимани е при использовании TT-калиб ровки для получения предсказа ний, которые непосред ственно сравниваются с экспериментальными данными.
