Automorphisms, derivations and central extensions of Lie algebras arising from quantum tori

For a Lie algebra $\mathfrak{g}$ related to a quantum torus, we compute its automorphisms, derivations and universal central extension. This Lie algebra $\mathfrak{g}$ is isomorphic to a subalgebra of the Lie algebra of derivations over the quantum torus, and moreover contains a subalgebra isomorphic to the centerless higher rank Virasoro algebra.
