Abstract
We derive a working model for the Tolman-Oppenheimer-Volkoff equation for
quark star systems within the modified f(T, T)-gravity class of
models. We consider f(T, T)-gravity for a static spherically
symmetric space-time. In this instance the metric is built from a more
fundamental tetrad vierbein from which the metric tensor can be derived. We
impose a linear f(T) parameter parameter, namely taking f=α T(r) +
βT(r) + φ and investigate the behavior of a linear
energy-momentum tensor trace, T. We also outline the restrictions
which modified f(T, T)-gravity imposes upon the coupling
parameters. Finally we incorporate the MIT bag model in order to derive the
mass-radius and mass-central density relations of the quark star within f(T,
T)-gravity.
