Abstract

The exact analytical solutions for vacuum electromagnetic fields of slowly rotating magnetized compact stars in conformal gravity have been studied. Taking the realistic dipolar magnetic field configuration for the star, analytical solutions of the Maxwell equations for the near zone magnetic and the electric fields exterior to a slowly rotating magnetized relativistic star in conformal gravity are obtained. In addition, the dipolar electromagnetic radiation and energy losses from the rotating magnetized compact star in conformal gravity have been studied. With the aim to find observational constraints on the LL parameter of conformal gravity, the theoretical results for the electromagnetic radiation from the rotating magnetized relativistic star in conformal gravity have been combined with the precise observational data on the radio pulsars periods slow down and it is estimated that the upper limit i.e. the maximum value of the parameter of conformal gravity is less than L9.5×105cmL \lesssim 9.5 \times 10^5\textrm{cm} (L/M5L/M \lesssim 5).
