  • Heber, U.; Edelmann, H.; Napiwotzki, R.; Altmann, M.; Scholz, R.D. (2008-05-01)
    Context. Young, massive stars have been found in the distant Galactic halo. Dynamical ejection from the Galactic disc has been suggested as the origin of these "run-away stars". The so-called hyper-velocity stars have been ...

    The Swift/Burst Alert Telescope detected the first burst from 1E 1841-045 in 2010 May with intermittent burst activity recorded through at least 2011 July. Here we present Swift and Fermi/Gamma-ray Burst Monitor observations ...
  • Lucas, P.W.; Roche, P.F. (1997-04-21)
    We present high-resolution, near-infrared images of a sample of five low-mass young stellar objects in the Taurus-Auriga dark cloud, mostly observed with the 'shift and add' technique, together with deep polarimetric images. ...

    We have calculated the cross sections for the charge symmetric reactions He-3(He-3,2p)He-4 and He-3(He-3,2p)He-4 at sub-Coulomb energies in the potential model. Good agreement with the experimental data is obtained. The ...

    Fission plays an important role in the r-process which is responsible; not only for the yields of transuranium isotopes, but may have a strong influence on the formation of the majority of heavy nuclei due to fission ...

    The neutron capture cross sections of (186,187,188)Os have been measured at the CERN neutron time-of-flight facility, n_TOF, in the neutron energy range from 1 eV up to 1 MeV. In this contribution, we report the results ...
