A Remark on "Forcedly Precession Neutron Star FRB180916.J0158+65" as a New Type Fast Radio Burst (FRB) Emission Source-Possibly be a Triaxial Pulsar?
Abstract
Motivated on the paper in Forcedly processing neutron star, FRB180916.J0158 + 65, and FRB121102 -MNRAS497, 1001 ? 1007 (2020) by Sob?yanin [1] an attempt has been made to search the nature of the neutron star in FRB180916.J0158+65. Using the observed parameters at the time of discovery I calculate the deformability (i.e. ellipticity ∈) due to the effect of internal magnetic field 6 x 10 14 G and 2 x 10 14 G inferred from the period activity 16.35 days and 157 days, respectively for rotational period 1s and found ∈ = 6 x 10 ? 4 and ∈ = 2 x 10 ? 4 accordingly. Considering the proposed limiting magnetic field for minimal deformation of a neutron star i.e. internal magnetic field < 1016 G, forcedly precession, deformation < (1 ? 2) % for treating spherical symmetry regime, it is possible for FRB180916.J0158+65 to satisfy the above conditions. It is concluded that the neutron star in FRB180916.J0158 + 65 is a "triaxial pulsar" which is a new type FRB emission source beyond the conventional / popular sources.
