    Most intermediate mass, pre-main-sequence Herbig Ae/Be stars reside in binary systems. As they are young, the properties of these systems allow us to constrain how they form. We have investigated the formation of Herbig ...

    Understanding the evolution of accretion activity is fundamental to our understanding of how galaxies form and evolve over the history of the Universe. We analyse a complete sample of 27 radio galaxies which includes both ...

    We have used blue near-infrared colours to select a group of 12 spectroscopically confirmed United Kingdom InfraRed Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) T dwarfs later than T4. From amongst these, we identify ...
  • Frischknecht, U.; Hirschi, R.; Meynet, G.; Ekstroem, S.; Georgy, C.; Rauscher, T.; Winteler, C.; Thielemann, F-K. (Cambridge University Press, 2010)
    The treatment of mixing is still one of the major uncertainties in stellar evolution models. One open question is how well the prescriptions for rotational mixing describe the real effects. We tested the mixing prescriptions ...

    The Goddard High Resolution Spectrograph (GHRS) of the Hubble Space Telescope (HST) has been used to observe the boron 2500 °A region of BD −13 3442. At a metallicity of [Fe/H]=−3.00 this is the most metal- poor star ever ...
  • Barnes, J R; James, D J; Cameron, A C (2002)
    With the advent of 8-m class telescopes and model atmospheres incorporating molecular opacities a great deal of interest has been directed towards the previously unexplored cool, low mass stars. M dwarfs are obviously a ...
  • Rauscher, T. (2006-01)
    The location of the (gamma,p)/(gamma,n) and (gamma,alpha)/(gamma,n) line at gamma process temperatures is discussed, using updated reaction rates based on global Hauser-Feshbach calculations. The results can be directly ...

    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 ...
