Abstract (EN): We consider astrophysical objects such as main-sequence stars, white-dwarfs, and neutron stars in a noncommutative context. Noncommutativity is implemented via a deformed dispersion relation E-2 = p(2)c(2)(1 + lambda E)(2) + m(2)c(4) from which we obtain noncommutative corrections to the pressure, particle number, and energy densities for radiation and for a degenerate fermion gas. The main implications of noncommutativity for the considered astrophysical objects are examined and discussed.
