We present our first attempt to model the atmosphere of the weakly activedM star with planets, GJ 876. We built a photospheric and chromospheric full NLTEmodel using the Solar Radiation Physical Modeling code (SRPM), which was upgradedto take into account molecular features that become important in the spectrum of acooler star than the Sun.
