  • The earliest fragmentation in molecular clouds : and its connection to star formation 

    Smith, Rowan Johnston (University of St Andrews, 2010-06-21) - Thesis
    Stars are born from dense cores of gas within molecular clouds. The exact nature of the connection between these gas cores and the stars they form is an important issue in the field of star formation. In this thesis I ...
  • The formation of molecular clouds in spiral galaxies 

    Dobbs, Clare L. (University of St Andrews, 2007-06-20) - Thesis
    Molecular clouds are imperative to astronomy as the sites of all known star formation. The problem of how molecular clouds are formed in spiral galaxies is approached numerically, by modelling the response of a gas ...
  • Formation of stars and stellar clusters in galactic environment 

    Smilgys, Romas (University of St Andrews, 2018-03-19) - Thesis
    Star and stellar cluster formation in spiral galaxies is one of the biggest questions of astrophysics. In this thesis, I study how star formation, and the formation of stellar clusters, proceeds using SPH simulations. These ...
  • Formation of stellar clusters 

    Smilgys, Romas; Bonnell, Ian Alexander (2017-12-21) - Journal article
    We investigate the triggering of star formation and the formation of stellar clusters in molecular clouds that form as the ISM passes through spiral shocks. The spiral shock compresses gas into 100 pc long main star formation ...
  • Gas flow and star formation in the centre of the Milky Way : investigations with smoothed particle hydrodynamics 

    Lucas, William (University of St Andrews, 2015-06-24) - Thesis
    The centre of the Milky Way, commonly referred to as the Galactic Centre, is roughly that region within 500 pc of the central black hole, Sagittarius A*. Within the innermost parsec around the supermassive black hole ...
  • The onset of gravitational collapse in molecular clouds 

    Clark, Paul Campbell (University of St Andrews, 2005) - Thesis
    We conduct an investigation into the role that turbulence plays in the formation of stars. In small clouds, with masses of ~ 30 Mʘ and where the turbulence is only injected at the start, we find that the turbulence does ...
  • Shocks, cooling and the origin of star formation rates in spiral galaxies 

    Bonnell, Ian Alexander; Dobbs, Clare L.; Smith, Rowan J. (2013-04-11) - Journal article
    Understanding star formation is problematic as it originates in the large-scale dynamics of a galaxy but occurs on the small scale of an individual star-forming event. This paper presents the first numerical simulations ...
  • Star formation across the galaxy : observations and modelling of the spectral energy distributions of young stars 

    Robitaille, Thomas P. (University of St Andrews, 2009-06-26) - Thesis
    In the last few decades, the emergence of large-scale infrared surveys has led to a revolution in the study of star formation. In particular, NASA’s Spitzer Space Telescope has recently carried out mid- and far-infrared ...
