  As part of a large survey of halo and thick disc stars, we found one halo
star, HD 106038, exceptionally overabundant in beryllium. In spite of its low
metallicity, [Fe/H] = -1.26, the star has log(Be/H) = -10.60, which is similar
to the solar meteoritic abundance, log(Be/H) = -10.58. This abundance is more
than ten times higher the abundance of stars with similar metallicity and
cannot be explained by models of chemical evolution of the Galaxy that include
the standard theory of cosmic-ray spallation. No other halo star exhibiting
such a beryllium overabundance is known. In addition, overabundances of Li, Si,
Ni, Y, and Ba are also observed. We suggest that all these chemical
peculiarities, but the Ba abundance, can be simultaneously explained if the
star was formed in the vicinity of a hypernova.
