Modelling and observations of molecules in discs around young stars [PDF]
, 2013 This thesis contains a study of molecules within circumstellar discs around young stars. Firstly, the chemistry of a disc around a young, Class 0 protostar is modelled.

Full-scale runback ice: accretion and aerodynamic study [PDF]
, 2010 The runback ice phenomenon is well-known for anti-icing or de-icing systems when the system is not evaporating 100% of the water impinging the surface.

Hoyle-Lyttleton Accretion onto Accretion Disks
Hoyle-Lyttleton Accretion onto Accretion DisksWe investigate Hoyle-Lyttleton accretion for the case where the central source is a luminous accretion disk. In Hoyle-Lyttleton accretion onto a "spherical" source, accretion takes place in an axially symmetric manner around a so-called accretion axis and the accretion rate M is given as M_(HL)(1 - Gamma)^2, where M_(HL) is the accretion rate of the ...

Modelling accretion in transitional disks [PDF]
Astronomy & Astrophysics, 2013 Transitional disks are protoplanetary disk around young stars that display inner holes in the dust distribution within a few AU, which is accompanied nevertheless by some gas accretion onto the central star. These cavities could possibly be created by the presence of one or more massive planets. If the gap is created by planets and gas is still present

Accretion Disk Evolution [PDF]
International Astronomical Union Colloquium, 1987 AbstractThree aspects of mass transfer instability models of dwarf novae are examined. The hydrodynamic development of instabilities in the secondary are examined within Roche geometry and shown to extend at least a few degrees away from the line of centres.

Accretion Disk Instabilities [PDF]
International Astronomical Union Colloquium, 1993 AbstractBasic properties of accretion disk instabilities are summarized. We first explain the standard disk model by Shakura and Sunyaev. In this model, the dominant sources of viscosity are assumed to be chaotic magnetic fields and turbulence in gas flow, and the magnitude of viscosity is prescribed by so-called a model. It is then possible to build a

Accretion and star formation in quasars [PDF]
, 2015 Studying the interplay of accretion and star formation is crucial to our understanding of galaxy evolution. The new generation of radio surveys are able to play a key role in this area, since both processes produce radio emission.

Accretion-powered stellar winds as a solution to the stellar angular momentum problem [PDF]
, 2005 We compare the angular momentum extracted by a wind from a pre-main-sequence star to the torques arising from the interaction between the star and its Keplerian accretion disk.
