  • Pavlenko, Ya.; Jenkins, J.; Jones, H.R.A.; Ivanyuk, O.; Pinfield, D.J. (2012)
    We describe our procedure to determine effective temperatures, rotational velocities, microturbulent velocities, and chemical abundances in the atmospheres of Sun-like stars. We use independent determinations of iron ...
  • Bailey, Jeremy; Ulanowski, Z.; Lucas, P. W.; Hough, J. H.; Hirst, E.; Tamura, M. (2008-05-11)
    In the past, it has generally been assumed that polarization observations made with ground-based telescopes are unaffected by the passage of light through the Earth's atmosphere. Here, we report observations with a new ...
  • Schawinski, K.; Kaviraj, S.; Khochfar, S.; Yoon, S.-J.; Yi, S.K.; Lee, Y.-W.; Deharveng, J.-M.; Boselli, A.; Donas, J.; Milliard, B.; Barlow, T.; Conrow, T.; Forster, K.; Friedman, P.G.; Martin, D.C.; Morrissey, P.; Seibert, M.; Small, T.; Wyder, T.; Neff, S.; Schiminovich, D.; Blanchi, L.; Heckman, T.; Szalay, A.; Madore, B.; Rich, R.M. (2007-12-01)
    We use GALEX near-UV (NUV ) photometry of a sample of early-type galaxies selected in the SDSS (Sloan Digital Sky Survey) to study the UV color-magnitude relation (CMR). NUV - r color is an excellent tracer of even small ...
  • Barnes, J. R.; Jeffers, S. V.; Jones, H.R.A. (2011-04)
    In light of the growing interest in searching for low mass, rocky planets, we investigate the impact of starspots on radial velocity searches for earth-mass planets in orbit about M dwarf stars. Since new surveys targeting ...
  • Gurney, Robert; Rhead, Mike; Martin, Bill; Ramalingam, Soodamani; Cohen, Neil (2013-12-16)
    The UK police service is one of the biggest users of ANPR technology in the world and over a number of years Police Forces have reported variances in ANPR performance based upon the retro-reflectivity properties of UK ...

  • Kaufman, M.; Struck, C.; Elmegreen, B.; Elmegreen, D.M.; Brinks, E.; Thomasson, M.; Klaric, M. (Astronomical Society of the Pacific, 2001)
    We made radio, optical and CO observations of three pairs of spiral galaxies involved in recent, grazing encounters and compared our data with numerical simulations. The tidal structures seen in the galaxy undergoing a ...
  • Shabala, S.; Kaviraj, S.; Silk, J. (2012-08)
    The effects of active galactic nucleus (AGN) feedback on group and cluster galaxies are investigated. We examine the colors of non-AGN hosts (i.e. satellite galaxies) by comparing galaxies overrun by radio AGN with similar ...
  • Granot, Jonathan (2012-04)
    Astrophysical sources of relativistic jets or outflows, such as gamma-ray bursts (GRBs), active galactic nuclei (AGN) or micro-quasars, often show strong time variability. Despite such impulsive behaviour, most models of ...

    We present spectropolarimetry of the solid CO feature at 4.67 μm along the line of sight to Elias 16, a field star background to the Taurus dark cloud. A clear increase in polarization is observed across the feature with ...
  • Silva, M.D.V.; Napiwotzki, Ralf (2011)
    We estimate the distribution of ejection velocities for the known population of high Galactic latitude runaway stars. The initial sample is a collection of 174 early-type stars selected from the literature. The stars are ...
  • Fulop, Zs.; Galaviz, D.; Gyurky, Gy.; Kiss, G. G.; Mate, Z.; Mohr, P.; Rauscher, T.; Somorjai, E.; Zilges, A. (American Institute of Physics, 2006)
    In order to improve the reliability of statistical model calculations in the region of heavy proton rich nuclei several elastic alpha scattering experiments have been carried out at low bombarding energies on various ...
  • Galaviz, D.; Fulop, Zs.; Gyurky, Gy.; Mate, Z.; Mohr, P.; Rauscher, T.; Somorjai, E.; Zilges, A. (2005-06)
    The cross sections for the elastic scattering reactions Sn-112,Sn-124(alpha,alpha)Sn-112,Sn-124 at energies above and below the Coulomb barrier are presented and compared to predictions for global alpha-nucleus potentials. ...

    We find that the rp process in X-ray bursts and in steady state burning, for example in X-ray pulsars, ends in a SnSbTe cycle. We discuss the consequences for the neutron star crust composition an X-ray burst light curves.
