This paper reports the investigation of a potential source of noise in the Laser Interferometer Space Antenna (LISA). The effect, not yet discussed in the literature, is a phase noise due to the presence of interplanetary dust along the path of LISA laser beams. The investigated source of noise has been found to be negligible in all the analyzed scenarios. We have estimated that the phase noise induced by the interplanetary dust complex is about 11 orders of magnitude below the best LISA sensitivity. A modest increase in the noise level has been found when dust fluctuations due to dust streams or nearby-passing comets are taken into account.

Abstract
This paper reports the investigation of a potential source of noise in the Laser Interferometer Space Antenna (LISA). The effect, not yet discussed in the literature, is a phase noise due to the presence of interplanetary dust along the path of LISA laser beams. The investigated source of noise has been found to be negligible in all the analyzed scenarios. We have estimated that the phase noise induced by the interplanetary dust complex is about 11 orders of magnitude below the best LISA sensitivity. A modest increase in the noise level has been found when dust fluctuations due to dust streams or nearby-passing comets are taken into account.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
