Neutron stars in $f(\mathtt{R},{\mathtt{L}}_{\mathtt{m}})$ gravity with realistic equations of state: joint-constrains with GW170817, massive pulsars, and the PSR J0030+0451 mass-radius from $NICER$ data

In this work we investigate neutron stars (NS) in $f(\mathtt{R},{\mathtt{L}}_{\mathtt{m}})$ theory of gravity for the case $f(\mathtt{R},{\mathtt{L}}_{\mathtt{m}})=\mathtt{R}+{\mathtt{L}}_{\mathtt{m}}+\sigma \mathtt{R}{\mathtt{L}}_{\mathtt{m}}$, wher…
