Irradiated Pulsar Planets and Companions as 511 keV Positron Annihilation Line Sources

Millisecond pulsars (MSPs) are prolific GeV γ -ray emitters, and nearly 80% of Fermi Large Area Telescope MSPs reside in compact binaries. For the first time in the literature, we demonstrate that the companions in these compact MSPs binaries are also 511 keV annihilation line emitters using MEGAlib...
