Stellar limits on scalars from electron-nucleus bremsstrahlung

We revisit stellar energy-loss bounds on the Yukawa couplings g$_{B,L}$ of baryophilic and leptophilic scalars ϕ. The white-dwarf luminosity function yields g$_{B}$ ≲ 7 × 10$^{-13}$ and g$_{L}$ ≲ 4 × 10$^{-16}$, based on bremsstrahlung from $^{12}$C and $^{16}$O collisions with electrons. In models...
