DOI: 10.1093/mnras/sty145
Abstract: The last decade has seen the detection of fast moving stars in the Galactic halo, the so-called hypervelocity stars (HVSs). While the bulk of this population is likely the result of a close encounter between… read more here.

DOI: 10.1093/mnras/sty1621
Abstract: In this study we present an analysis of a sample of field blue straggler (BS) stars that show high ultra violet emission in their spectral energy distributions (SED): indication of a hot white dwarf (WD)… read more here.
