    • Positron Annihilation in the Galaxy 

      Kierans, C.~A.; Beacom, J.~F.; Boggs, S.; Buckley, M.; Caputo, R.; Crocker, R.; De Becker, M.; Diehl, R.; Fryer, C.~L.; Griffin, S.; Hartmann, D.; Hays, E.; Jean, P.; Krause, M.~G.~H.; Linden, T.; Marcowith, A.; Martin, P.; Moiseev, A.; Oberlack, U.; Orlando, E.; Panther, F.; Prantzos, N.; Rothschild, R.; Seitenzahl, I.; Shrader, C.; Siegert, T.; Strong, A.; Tomsick, J.; Vestrand, W.~T.; Zoglauer, A. (2019-03-13)
      The 511 keV line from positron annihilation in the Galaxy was the first γ-ray line detected to originate from outside our solar system. Going into the fifth decade since the discovery, the source of positrons is still ...

    • Superbubble dynamics in globular cluster infancy. I. How do globular clusters first lose their cold gas? 

      Krause, M.; Charbonnel, C.; Decressin, T.; Meynet, G.; Prantzos, N.; Diehl, R. (2012-10-05)
      The picture of the early evolution of globular clusters has been significantly revised in recent years. Current scenarios require at least two generations of stars of which the first generation (1G), and therefore also the ...

    • Superbubble dynamics in globular cluster infancy. II. Consequences for secondary star formation in the context of self-enrichment via fast-rotating massive stars 

      Krause, M.; Charbonnel, C.; Decressin, T.; Meynet, G.; Prantzos, N. (2013-04-12)
      Context. The self-enrichment scenario for globular clusters (GC) requires large amounts of residual gas after the initial formation of the first stellar generation. Recently, we found that supernovae may not be able to ...
