Asymmetrical tidal tails of open star clusters: stars crossing their cluster's práh<SUP>†</SUP> challenge Newtonian gravitation
After their birth a significant fraction of all stars pass through the tidal threshold (práh) of their cluster of origin into the classical tidal tails. The asymmetry between the number of stars in the leading and trailing tails tests gravitational theory. All five open clusters with tail data (Hyades, Praesepe, Coma Berenices, COIN-Gaia 13, NGC
