The work is concerned with the charged analogue of Bayin's paper (1978) related to Tolman's type astrophysically interesting aspects of stellar structure.

Static spherically symmetric charged dust models, known as Lane-Emden electromagnetic mass models, having their seed in the well-known Lane-Emden equations of classical astrophysics, have been derived for Einstein-Cartan theory. The models are of purely electromagnetic origin. The physical significance of these solutions can be understood from the very fact (i) that they are generated from the well-known Lane-Emden equations of classical astrophysics having a proven physical foundation and (ii) that, being the solution of Einstein-Cartan theory, they involve spin and torsion, characteristics which a material system must possess for its subtle and finer details.

The present work is a continuation of our earlier work on the charged dust sources of purely electromagnetic origin for static axisymmetric and static spherically-symmetric fields. Here we have extended the above work to the case of generalized static metric and have shown that a static charged dust distribution, irrespective of any symmetry conditions, can be only of purelly electromagnetic origin. Incidentally, it follows from this result itself that the ‘Weyl-Majumdar-Papapetrou’ class of static charged dust sources, which form an important class of astrophysical systems, are also of purely electromagnetic origin.

This paper presents a set of solutions of coupled Einstein-Maxwell equations with matter for the Levi-Civita's metric which can be interpreted as electromagnetic mass models which are extensions of the electromagnetic mass models obtained previously. It may be pointed out that electromagnetic mass models are solutions of coupled Einstein-Maxwell equations with matter where all the characteristics of matter vanish when the charge vanishes. Existence of such solution tends to confirm Lorentz's conjecture that the mass of an electron may be of purely electromagnetic origin.
