  • Atmospheres of brown dwarfs 

    Helling, Christiane; Casewell, Sarah (2014) - Journal article
    Brown Dwarfs are the coolest class of stellar objects known to date. Our present perception is that Brown Dwarfs follow the principles of star formation, and that Brown Dwarfs share many characteristics with planets. Being ...

    Favier, V.; Verfaillie, D.; Berthier, E.; Menegoz, M.; Jomelli, V.; Kay, J. E.; Ducret, L.; Malbéteau, Y.; Brunstein, D.; Gallée, H.; Park, Y. -H.; Rinterknecht, V. (2016-09-01) - Journal article
    The ongoing retreat of glaciers at southern sub-polar latitudes is particularly rapid and widespread. Akin to northern sub-polar latitudes, this retreat is generally assumed to be linked to warming. However, no long-term ...

    Detailed observations of the solar system planets reveal a wide variety of local atmospheric conditions. Astronomical observations have revealed a variety of extrasolar planets none of which resembles any of the solar ...
  • Atmospheric origins of perchlorate on Mars and in the Atacama 

    Catling, D. C.; Claire, Mark; Zahnle, K. J.; Quinn, R. C.; Clark, B. C.; Hecht, M. H.; Kounaves, S. (2010) - Journal article
    Isotopic studies indicate that natural perchlorate is produced on Earth in arid environments by the oxidation of chlorine species through pathways involving ozone or its photochemical products. With this analogy, we propose ...
  • Atmospheric transport and critical layer mixing in the troposphere and stratosphere 

    Smy, Louise Ann (University of St Andrews, 2012-06-22) - Thesis
    This thesis aims to improve the understanding of transport and critical layer mixing in the troposphere and stratosphere. A dynamical approach is taken based on potential vorticity which has long been recognised as the ...

  • Atonement at the right hand: the sacrificial significance of Jesus’ exaltation in Acts 

    Moffitt, David M. (2016-10) - Journal article
