## Abstract

Our aim is to investigate tidal interaction in High-Mass X-ray Binary stars in order to determine in which objects the rotation of the mass donors is synchronized or pseudosynchronized with the orbital motion of the compact companion. We calculate the pseudosynchronization period (P\_ps) and compare it with the rotational period of the mass donors (P\_rot). We find that   (1) the Be/X-ray binaries are not synchronized, the mass donors rotate faster than the orbital period and the ratio P\_ps/P\_rot is 2-300;   (2) the giant and supergiant systems are close to synchronization and for them the ratio P\_ps/P\_rot is 0.3-2.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
