The Palatini star: exact solutions of the modified Lane–Emden equation
Abstract Two exact solutions for $$n=0$$ n=0 and $$n=1$$ n=1 of the Palatini-modified Lane–Emden equation are found. We have employed these solutions to describe a Palatini–Newtonian neutron or low mass brown dwarf star and compared the result with the pure Newtonian counterpart. It turned out that...
