  • Riaz, Basmah; Gizis, John E. (2007-05-20)
    We present detailed modeling of the disk around the TW Hydrae Association (TWA) brown dwarf 2MASSW J1207334 - 393254 (2M1207), using Spitzer observations from 3.6 to 24 mu m. The spectral energy distribution (SED) does not ...

    The astrophysical site of the r-process is still uncertain, and a full exploration of the systematics of this process in terms of its dependence on nuclear properties from stability to the neutron drip-line within realistic ...

(2014-05)
    We present the Chasing the Identification of ASCA Galactic Objects (ChIcAGO) survey, which is designed to identify the unknown X-ray sources discovered during the ASCA Galactic Plane Survey (AGPS). Little is known about ...

  • Kobayashi, Chiaki; Tominaga, Nozomu; Nomoto, Ken'ichi (2011-04-01)
    We show that the recently observed elemental abundance pattern of the carbon-rich metal-poor damped Ly alpha (DLA) system is in excellent agreement with the nucleosynthesis yields of faint core-collapse supernovae of ...
  • Vonlanthen, P.; Rauscher, T.; Winteler, C.; Puy, D.; Signore, M.; Dubrovich, V. (2009-08)
    Context. Primordial molecules were formed during the Dark Ages, i.e. the time between recombination and reionization in the early Universe. They were the constituents of the first proto-stellar clouds. Standard Big Bang ...
  • Kobayashi, C. (2004-01)
    We simulate the chemodynamical evolution of a hundred elliptical galaxies using our GRAPE-SPH code, and succeed in reproducing the radial metallicity gradients and the global scaling relations such as the fundamental plane. ...
  • Kobayashi, C. (2002-07)
    I simulate the chemodynamical evolution of the Milky Way and elliptical galaxies using the GRAPE-SPH code. By reproducing the observations, I discuss the origin of elliptical galaxies
  • Kobayashi, C.; Nakasato, N.; Nomoto, K. (Astronomical Society of the Pacific, 2003)
    We simulate the chemodynamical evolution of the Milky Way using our GRAPE-SPH code, and reproduce the age-metallicity relation, the [O/Fe]-[Fe/H] relation, and the metallicity distribution.
  • Kobayashi, Chiaki (American Institute of Physics, 2010)
    We predict the frequency distribution of elemental abundance ratios from Carbon to Zinc as a functions of time and location, which can be directly compared with the next generation of the galactic archeology project such ...
  • Kobayashi, Chiaki (Cambridge University Press, 2010)
    We simulate the formation and evolution of galaxies with a self-consistent 3D hydrodynamical model including star formation, supernova feedback, and chemical enrichment. Hypernova feedback plays an essential role not only ...
  • Kobayashi, Chiaki (Cambridge University Press, 2009)
    We simulate the chemodynamical evolution of the Milky Way Galaxy, including the nucleosynthesis yields of hypernovae and a new progenitor model for Type la Supernovae (SNe la). In our nucleosynthesis yields of core-collapse ...
  • Kobayashi, Chiaki; Nakasato, Naohito (2011-03-01)
    We present chemodynamical simulations of a Milky-Way-type galaxy using a self-consistent hydrodynamical code that includes supernova feedback and chemical enrichment, and predict the spatial distribution of elements from ...
  • Kobayashi, Chiaki (American Institute of Physics, 2010)
    Using self-consistent chemodynamical simulations including star formation, supernova feedback, and chemical enrichment, I show the dependence of the initial mass function (IMF) on cosmic star formation and chemical enrichment ...

  • Almeida, C. Ramos; Dicken, D.; Tadhunter, C.; Asensio Ramos, A.; Inskip, K. J.; Hardcastle, M.J.; Mingo, B. (2011-06)
    We report the clearest detection to date of dusty torus signatures in a weak-line radio galaxy (WLRG). The deep Spitzer InfraRed Spectrograph (IRS) rest-frame mid-infrared (MIR) spectrum of the WLRG PKS 0043-42 (z = 0.116) ...
