which corresponds to about 0.25 M$_\odot$. A comparison with an N-body model of the cluster and its tails shows remarkably good coincidence. Three new white dwarfs are found in the tails.]{}

Introduction {#intro}
============

Tidal tails around open clusters have been predicted about a decade ago by, e.g. and . An introduction to this topic was given in our previous paper , hereafter called Paper I, and is not repeated here. The first detection of tidal tails of open clusters using the data from Gaia Data Release 2 were reported at the end of 2018 by and who revealed the tidal tails of the Hyades. This was followed by a number of publications where tidal tails have now been found around other open clusters. @2019arXiv190201404T and @2019arXiv190207216F recently reported about the detection of tidal tails of the Coma Berenices (Melotte 111) open cluster, and @2019arXiv190104253Y give hints for tidal tails from the very old, $\log \rm{t}$ = 9.33 , open cluster Ruprecht 147. So, tidal tails now seem to be a common feature of older open clusters and are revealed thanks to the high data quality of Gaia DR2.

NGC 2632 (Praesepe) is an old open cluster, $\log \rm{t}$ =
