  With the help of molecular dynamics simulations we study an ensemble of
active dumbbells in purely repulsive interaction. We derive the phase diagram
in the density-activity plane and we characterise the various phases with
liquid, hexatic and solid character. The analysis of the structural and
dynamical properties, such as enstrophy, mean square displacement,
polarisation, and correlation functions, shows the continuous character of
liquid and hexatic phases in the coexisting region when the activity is
increased starting from the passive limit.
