Abstract
We show that recent supernova explosion(s) in a molecular cloud (MC) near the Earth can be attributed to the electron/positron excesses observed with PAMELA and ATIC. Protons are accelerated around the supernova remnant (SNR). Since the SNR is in a radiative phase, the proton spectrum is harder than that of the background. Electrons and positrons are created through hadronic interactions insides the MC. Our model predicts that the anti-proton flux dominates that of the background for ~>100 GeV.
