The original version of this article unfortunately contained a mistake. The last sentence in the first paragraph under Section 3 “Motion in a central field” incorrectly read: “With these models, the integrations in (40)–eqrefeq41 done only within the radius \(R_0(t)\) of the star, lead to the solution ...”. The correct information is “With these models, the integrations in (40)–(43) done only within the radius \(R_0(t)\) of the star, lead to the solution ...”.

The original article has been corrected.
