Here we construct three possible models of nucleon-hyperon matter consistent with the existence of $2~M_\\odot$ pulsars as well as with semi-empirical nuclear matter parameters at saturation, and semi-empirical hypernuclear data. Our aim is to calculate for these models all the parameters necessary for modelling dynamics of hyperon stars (such as equation of state, adiabatic indices, thermodynamic derivatives, re","authors_text":"(2) CAMK), E.M.
