The baryonic properties of neutron stars within the theory of pseudo‐complex General Relativity (pc‐GR) are studied. The pc‐Tolman‐Oppenheimer‐Volkoff equations are numerically integrated in order to understand the structure of these objects. The pc‐component energy density ϵ Λ has been linearly coupled to the respective baryonic quantity ϵ m . Solutions have been presented for different values of the coupling parameter. It is shown that accumulation of the Λ‐component allows the theoretical existence of larger and more massive neutron stars. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
