TL;DR
This paper investigates the potential for detecting Shapiro delay effects caused by asteroids near LISA, concluding such events are highly unlikely to be observed during the mission.
Contribution
It provides a quantitative assessment of the likelihood of asteroid-induced Shapiro delays affecting LISA observations, a novel analysis for space-based gravitational wave detectors.
Findings
Probability of detectable asteroid Shapiro delay < 1%
Asteroid events unlikely to impact LISA data
Quantitative analysis of asteroid proximity events
Abstract
In this paper, we examine the Shapiro delay caused by the close approach of an asteroid to the LISA constellation. We find that the probability that such an event occurs at a detectable level during the time interval of the mission is smaller than 1 %.
