    A study of harmony and formal functions in dance music of the 18th and early 19th centuries. The data and analyses are also intended to supplement the form theory presented in William E. Caplin, Classical Form: A Theory ...
  • The Dark Matter Density Profile Of The Fornax Dwarf 

    Jardel, John R.; Gebhardt, Karl (2012-02)
    We construct axisymmetric Schwarzschild models to measure the mass profile of the Local Group dwarf galaxy Fornax. These models require no assumptions to be made about the orbital anisotropy of the stars, as is the case ...
  • Dark Matter Scaling Relations And The Assembly Epoch Of Coma Early-Type Galaxies 

    Thomas, Jens; Saglia, R. P.; Bender, Ralf; Thomas, D.; Gebhardt, Karl; Magorrian, John; Corsini, E. M.; Wegner, G. (2009-01)
    Axisymmetric, orbit-based dynamical models are used to derive dark matter scaling relations for Coma early-type galaxies. From faint to bright galaxies, halo core radii and asymptotic circular velocities increase. Compared ...
  • A Dark Spot On A Massive White Dwarf 

    Kilic, Mukremin; Gianninas, Alexandros; Bell, Keaton J.; Curd, Brandon; Brown, Warren R.; Hermes, J. J.; Dufour, P.; Wisniewski, J. Patrick; Winget, D. E.; Winget, K. I. (2015-12)
    We present the serendipitous discovery of eclipse-like events around the massive white dwarf SDSS J152934.98+292801.9 (hereafter J1529+2928). We selected J1529+2928 for time-series photometry based on its spectroscopic ...
  • Dark Stars: Improved Models And First Pulsation Results 

    Rindler-Daller, T.; Montgomery, Michael H.; Freese, K.; Winget, D. E.; Paxton, B. (2015-02)
    We use the stellar evolution code MESA to study dark stars (DSs). DSs, which are powered by dark matter (DM) self-annihilation rather than by nuclear fusion, may be the first stars to form in the universe. We compute stellar ...
  • Data-Base for your Company? 

    Scott, George M. (1976-09)
    Common data bases are now trumpeted as providing companies deliverance from a variety of information systems maladies. The author presents a down-to-earth manager's perspective of these data bases in answering the basic ...
