Application of adaptive optics to the spectroscopic investigation of small-scale solar structures
… using the results of a three-dimensional magneto-hydrodynamical model as input for a radiative transfer calculation, but find little agreement with our observations. The core intensity of the G-band CH lines is significantly influenced by the atmospheric conditions in heights of 160 km and 320 km, …

Measuring and modelling estuarine macroalgae blooms and water column nutrients
… them, using process-based mathematical models as well as observation data from Tauranga Harbour (North Island, New Zealand). Based on long-term monitoring datasets of water column nutrients, temperature and irradiance, the Ulva tissue nitrogen concentration is modelled using an algebraic …

Present and early star formation : a study on rotational and thermal properties
… angular momentum of prestellar cores in our models agree remarkably well with observations of cloud cores. Some prestellar cores go into collapse to build up stars and stellar systems. The resulting protostellar objects have specific angular momenta that fall into the range of observed …

Weakly collisional electrostatic simulations for laboratory astrophysics applications
… and novel numerical approach to accurately model high energy plasma dynamics, with arbitrary collisionality. This approach is particularly suited to modelling the weakly collisional regime. The code developed to implement this novel simulation method adopts a hybrid approach, in that it …
