Young Blue Straggler Stars in the Galactic Field

  title={Young Blue Straggler Stars in the Galactic Field},
  author={Gemunu Ekanayake and Ronald W. Wilhelm},
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) companion to BS. Using photometry available in the Sloan Digital Sky Survey (SDSS) and Galaxy Evolution Explorer (GALEX ) surveys we identified 80 stars with UV excess. To determine the parameter distributions (mass, temperature and age) of the WD companions, we developed a fitting routine that… CONTINUE READING
