On the global electrostatic charge of stars

As was discovered in the nineteen-twenties, a significant electric field ex ists in the solar corona as well as in the solar interior. This field is a consequence of the tendency of light electrons to segregate from heavier pr otons in the solar gravitational field. Since the principle is valid for a plasma in every star, the result can be generalized. The presented paper is intended to rehighlight this significant physical property of stars. In pa rticular, we stress that there has to be charge Q(r) inside a stellar spher e with radius r, which is linearly proportional to mass M-r inside the sphe re. Both quantities are related as Q(r) = 77.043M(r), if Q(r) is given in C oulombs and M-r in solar masses. The global stellar electrostatic field is 918 times stronger than the corresponding stellar gravity and compensates f or a half of the gravity, when it acts on an electron or proton, respective ly. The external electric field has to cause an occurence of electric curre nt and appropriate magnetic field in a highly conductive plasma, when, e.g. , the plasma is in a turbulent motion or spirals onto a star in a hot accre tion disc.
