We report a theoretical study of dissociative recombination (DR) of BeH+ by low energy electron impact, using previously computed molecular data as input for a Multichannel Quantum Defect Theory (MQDT) approach. Three electronic symmetries of BeH, 2Π, 2Σ+, and 2Δ have been included in the calculations. We present cross sections and thermal rate coefficients ready to be used in the modelling of the BeH+ abundance in the interstellar medium and stellar atmosphere.
