The study of different star-forming regions and their stellar populations, as well as the reconstruction of their star formation history and structure need astrometric and kinematic data with the lowest levels of uncertainty possible. Thanks to the Gaia satellite (Gaia Collaboration et al.

The effects of anisotropy on the fluid pulsation modes when adopting the so-called Cowling approximation and the tidal deformability of strange-quark stars are investigated by numerically integrating the hydrostatic equilibrium, nonradial oscillation, and tidal deformability equations, all of which are modified from their standard form to include the anisotropic effects. The fluid matter inside compact stars is described by the MIT bag model equation of state.
