Query: Neutral compact spherically symmetric stars in teleparallel gravity   We present novel neutral and uncharged solutions that describe the cluster of
Einstein in the teleparallel equivalent of general relativity (TEGR). To this
end, we use a tetrad field with non-diagonal spherical symmetry which gives the
vanishing of the off-diagonal components for the gravitational field equations
in the TEGR theory. The clusters are calculated by using an anisotropic
energy-momentum tensor. We solve the field equations of TEGR theory, using two
assumptions: the first one is by using an equation of state that relates
density with tangential pressure while the second postulate is to assume a
specific form of one of the two unknown functions that appear in the
non-diagonal tetrad field. Among many things presented in this study, we
investigate the static stability specification. We also study the
Tolman-Oppenheimer-Volkoff equation of these solutions in addition to the
conditions of energy. The causality constraints with the adiabatic index in
terms of the limit of stability are discussed.
