  • Sun, Dongfa; Sun, Genlou (Public Library Science, 2012-12-10)
    Numerous hybrid and polypoid species are found within the Triticeae. It has been suggested that the H subgenome of allopolyploid Elymus (wheatgrass) species originated from diploid Hordeum (barley) species, but the role ...

    Using the high-resolution performance of the fragment separator FRS at GSI we have discovered 60 new neutron-rich isotopes in the atomic number range of 60⩽ Z ⩽ 78. The new isotopes were unambiguously identified in reactions ...

  • Ripepi, v.; Moretti, M. I.; Marconi, M.; Clementini, G.; Cioni, M.-R. L.; Marquette, J. B.; Girardi, L.; Rubele, S.; Groenewegen, M. A. T.; de Grijs, R.; Gibson, Brad K. (Oxford University Press, 2012-08)
    The VISTA Magellanic Cloud (VMC; PI: M.-R. L. Cioni) survey is collecting deep Ks-band time series photometry of the pulsating variable stars hosted by the system formed by the two Magellanic Clouds (MCs) and ...

    Using the Radial Velocity Experiment (RAVE) survey, we recently brought to light a gradient in the mean galactocentric radial velocity of stars in the extended solar neighbourhood. This gradient likely originates from ...

  • Sanchez-Blazquez, P.; Marcolini, A.; Gibson, Brad K.; Karakas, A. I.; Pilkington, K.; Calura, F. (Oxford University Press, 2012)
    In the first paper of this series, we proposed a new framework in which to model the chemical evolution of globular clusters. This model is predicated upon the assumption that clusters form within an interstellar medium ...

  • Saio, H.; Gruberbauer, Michael; Weiss, W. W.; Matthews, J. M.; Ryabchikova, T. (Wiley-Blackwell, 2012-02)
    Precise time series photometry with the MOST satellite has led to identification of 10 pulsation frequencies in the rapidly oscillating Ap (roAp) star HD134214. We have fitted the observed frequencies with theoretical ...

  • Snaith, O. N.; Gibson, Brad K.; Brook, C. B.; Knebe, A.; Thacker, Robert John, 1970-; Quinn, T. R.; Governato, F.; Tissera, P. B. (Oxford University Press, 2012)
    We examine the properties and evolution of a simulated polar disc galaxy. This galaxy is composed of two orthogonal discs, one of which contains old stars (old stellar disc) and the other both younger stars and cold gas ...

  • Pilkington, K.; Gibson, Brad K.; Brook, C. B.; Calura, F.; Stinson, G. S.; Thacker, Robert John, 1970-; Michel-Dansac, L.; Bailin, J.; Couchman, H. M. P.; Wadsley, J. (Oxford University Press, 2012)
    We examine the chemical properties of five cosmological hydrodynamical simulations of an M33-like disc galaxy which have been shown previously to be consistent with the morphological characteristics and bulk scaling relations ...

  • Williamson, David John; Thacker, Robert John, 1970- (Wiley-Blackwell, 2012-04)
    Analytic estimates of the viscous time-scale due to cloud–cloud collisions have been as high as thousands of Gyr. Consequently, cloud collisions are widely ignored as a source of viscosity in galactic discs. However, ...

  • Turner, David Gerald, 1945-; Majaess, Daniel J.; Lane, D. J.; Balam, D. D.; Gieren, W. P.; Storm, J.; Forbes, D. W.; Havlen, R. J.; Alessi, B. (Wiley-Blackwell, 2012-05)
    The parameters for the newly discovered open cluster Alessi 95 are established on the basis of available photometric and spectroscopic data, in conjunction with new observations. Colour excesses for spectroscopically ...

  • Stinson, G. S.; Brook, C.; Prochaska, J. Xavier; Hennawi, Joe; Shen, Sijing; Wadsley, J.; Pontzen, Andrew; Couchman, H. M. P.; Quinn, T.; Maccio, Andrea V.; Gibson, Brad K. (Wiley-Blackwell, 2012-09)
    We explore the circumgalactic medium (CGM) of two simulated star-forming galaxies with luminosities L≈0.1 and 1 L generated using the smooth particle hydrodynamic code GASOLINE. These simulations are part ...

  • Majaess, Daniel J.; Turner, David Gerald, 1945-; Gieren, W. (Wiley-Blackwell, 2012-04)
    Preliminary constraints are placed on a cluster of young stellar objects (J2000 02:54:31.4 +69:20:32.5) discovered in the field of the classical Cepheid SU Cas. The Wide-field Infrared Survey Explorer (WISE) 3.4-, 4.6-, ...

  • Hill, Kenneth Anthony (Social Judgement and Decision Making, 2012-07)
    A type of emergency decision-making which has not received research attention is the police search for a lost person in a rural or wilderness area. For many such incidents, decisions concerning where to search for the lost ...

  • Pisano, D. J.; Barnes, David G.; Staveley-Smith, Lister; Gibson, Brad K.; Kilborn, Virginia A.; Freeman, Ken C. (IOP Publishing Limited, 2011-12)
    We have conducted an Hi 21 cm emission-line survey of six loose groups of galaxies chosen to be analogs to the Local Group. The survey was conducted using the Parkes multibeam instrument and the Australia Telescope Compact ...

  • White, Timothy R.; Bedding, Timothy R.; Gruberbauer, Michael; Benomar, Othman; Stello, Dennis; Appourchaux, Thierry; Chaplin, William J.; Christensen-Dalsgaard, Jorgen; Elsworth, Yvonne P.; Garcia, Rafael A. (IOP Publishing Limited, 2012-06-01)
    Asteroseismology of F-type stars has been hindered by an ambiguity in identification of their oscillation modes. The regular mode pattern that makes this task trivial in cooler stars is masked by increased line widths. The ...

  • Majaess, Daniel J.; Turner, David Gerald, 1945-; Gieren, W. (IOP Publishing Limited, 2012-03-10)
    New and existing UBVJHKs, spectroscopic, NOMAD, Hubble Space Telescope, and revised Hipparcos observations are employed to determine properties for δ Cep and its host star cluster. The multi-faceted approach ...

  • Short, C. Ian (Christopher Ian), 1965-; Campbell, Eamonn A.; Pickup, Heather; Hauschildt, Peter H. (IOP Publishing Limited, 2012-03-10)

    The GJ 581 system has been amply studied since its discovery in 2005: the number of known planets in the system has increased and their orbital parameters are among the most precisely determined for radial-velocity-detected ...

  • Majaess, Daniel J.; Turner, David Gerald, 1945-; Gieren, W.; Balam, D.; Lane, D. J. (IOP Publishing Limited, 2012-03-20)
    New and existing CORAVEL, UBVJHKs, HST, HIP/Tycho, ARO, KPNO, and DAO observations imply that the fundamental Cepheid calibrator ζ Gem is a cluster member. The following parameters were inferred for ζ ...

    Approximately 14% of known Galactic open clusters possess absolute errors ≤20% as evaluated from n ≥ 3 independent distance estimates, and the statistics for age estimates are markedly worse. That impedes such diverse ...
