We derive model-independent astrophysical constraints on leptophilic darkmatter (DM), considering its thermal production in a supernova core and takinginto account core temperature fluctuations within the framework of $q$-deformedTsallis statistics. In an effective field theory approach, where the DMfermions interact with the Standard Model via dimension-six operators of eitherscalar-pseudoscalar, vector-axial vector, or tensor-axial tensor type, weobtain bounds on the effective cut-off scale $\Lambda$ from supernova coolingand free-streaming of DM from supernova core, and from thermal relic densityconsiderations, depending on the DM mass and the $q$-deformation parameter.Using Raffelt's criterion on the energy loss rate from SN1987A, we obtain alower bound on $\Lda \gtrsim 3$ (12) TeV corresponding to $q = 1.0~(1.1)$ andan average supernova core temperature of $T_{\rm SN}=30$ MeV. From the opticaldepth criterion on the free-streaming of DM fermions from the outer 10\% of theSN1987A core, the cooling bound is restricted to $\Lda \gtrsim 1$ TeV. Bothcooling and free-streaming bounds are insensitive to the DM mass $m_\chi$ for$m_\chi\lesssim T_{\rm SN}$, whereas for $m_\chi\gg T_{\rm SN}$, the boundsweaken significantly due to the Boltzmann-suppression of the DM number density.We also calculate the thermal relic density of the DM particles in this setupand find that it imposes an upper bound on $\Lambda^4/m_\chi^2$, which togetherwith the cooling/free-streaming bound significantly constrains lightleptophilic DM.
