  • Local models of astrophysical discs 

    Latter, Henrik Nils; Papaloizou, John Christopher (Oxford University PressMonthly Notices of the Royal Astronomical Society, 2017-12-01)
    Local models of gaseous accretion discs have been successfully employed for decades to describe an assortment of small-scale phenomena, from instabilities and turbulence, to dust dynamics and planet formation. For the most ...

  • Spin alignment and differential accretion in merging black-hole binaries 

    Gerosa, D; Veronesi, B; Lodato, G; Rosotti, Giovanni Pietro (Oxford University PressMonthly Notices of the Royal Astronomical Society, 2015-06-29)
    Interactions between a supermassive black-hole binary and the surrounding accretion disc can both assist the binary inspiral and align the black-hole spins to the disc angular momentum. While binary migration is due to ...

  • Spiral density waves and vertical circulation in protoplanetary discs 

    Latter, Henrik Nils; Riols, Antoine (Oxford University PressMonthly Notices of the Royal Astronomical Society, 2018-06-01)
    Spiral density waves dominate several facets of accretion disc dynamics – planet-disc interactions and gravitational instability (GI) most prominently. Though they have been examined thoroughly in two-dimensional simulations, ...

  • Zonal flows in accretion discs and their role in gravito-turbulence 

    Vanon, Riccardo (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics (DAMTP)St Edmund's, 2017-10-01)
    This thesis focuses on the evolution of zonal flows in self-gravitating accretion discs and their resulting effect on disc stability; it also studies the process of disc gravito-turbulence, with particular emphasis given ...
