\abstract{
  Observations in the hard X-ray band found that electrons are accelerated in two magnetic white dwarfs. Protons are found to be accelerated to GeV in the novae by Fermi.These prompted us to analyze the cosmic ray (CR) spectra of electrons, protons, and heavier nuclei observed near Earth including the spectra deduced from the observed hard X-ray and gamma ray spectra. We fit the CR spectra at the heliopause using two templates for each species: one representing the CRs from WDs/novae accumulated in the local bubble and the other representing the CRs in the Galaxy. The CR spectra deduced from the hard X-ray and gamma ray spectra are refitted so that the sums of the local and Galactic reproduce the CR spectra at the heliopause. We find one local template and one Galactic template fit all nuclear CR spectra at heliopause and that the hardening of the nuclear CRs is interpreted as due to the roll-down of the CR contributions from WDs/novae at around a few 100GeV. The GeV hump in the gamma ray emissivity found in the inner Galaxy in the Fermi-LAT emissivity analysis is attributed to the CRs from WDs. .
