Abstract

This study includes detailed exploration of Vela pulsar magnetosphere and glitches—including recent studies that compare Vela pulsar with other pulsars such as: PSR B0329+54, an optical pulsar (the Crab pulsar, PSR B0531+21), an old millisecond pulsar (PSR J0437-4715) and the 2nd fastest known pulsar (PSR B1937+21). The explored energy band shows γ-ray to be the strongest in emission.Its helical structure and magneto-dynamic instability give further insight to this. Exploration of the magnetosphere shows the effect of pair production and gap on Lorentz factor that is balanced between electric and radiation reaction force—and how that is affected within a boundary. We further explore the magnetosphere in terms of X-ray field, curvature radiation-outside the gap, electric structure, γ-ray spectrum and spectral dependence on the curvature of field line to understand Vela pulsar better. This, we combine with Gvaramadze’s study to prove the relationship of the pulsar velocity with distance.
