Popis:	Aether Scalar-Tensor theory is a modification of general relativity proposed to explain galactic and cosmological mass discrepancies conventionally attributed to dark matter. The theory is able to fit the cosmic microwave background and the linear matter power spectrum without dark matter. In this work, we derive the Tolman-Oppenheimer-Volkoff equation in this theory and solve it for realistic nuclear equations of state to predict the mass-radius relation of neutron stars. We find solutions that are compatible with all current observations of neutron stars. Comment: 10 pages, 3 figures
