We analyse the temperature anisotropy of the protons in the solar wind and thereby concentrate on plasma data obtained in the year 1976 of the Helios 1 and Helios 2 missions. We derive the core proton temperatures and . in the directions perpendicular and parallel to the magnetic field. as well as the core parallel plasma beta. https://www.roneverhart.com/Super-Sensitive-SS2102-Red-Label-1-8-Violin-String-Set-p28087/
