TL;DR
This paper investigates the distribution of stars in tidal tails of star clusters, revealing that even in steady tidal conditions, stars tend to cluster at specific distances far from the cluster.
Contribution
It combines theoretical analysis and simulations to demonstrate the presence of maxima in star distribution along tidal tails at large distances from the cluster.
Findings
Maxima in star distribution occur at many tidal radii from the cluster.
Distribution exhibits peaks even under steady tidal conditions.
The study enhances understanding of star escape patterns in tidal tails.
Abstract
We examine the longitudinal distribution of the stars escaping from a cluster along tidal tails. Using both theory and simulations, we show that, even in the case of a star cluster in a circular galactic orbit, when the tide is steady, the distribution exhibits maxima at a distance of many tidal radii from the cluster.
