An observational and modeling study of a heavy orographic precipitation event over the Oregon Cascades
… terrain. The collection of thermodynamic and kinematic observations concomitantly with microphysical measurements also provided a unique chance to isolate errors in a mesoscale scale model's microphysical parameterization which may be contributing to errors in quantitative precipitation …

Circumstellar environments around the youngest protostars: interferometric observations and modeling
… orientation, the dust continuum shows spherical structures at scales between ~10^2 and ~10^3 AU. The N2H+ observations not only reveal the outer envelope that is too dim to be detected in dust continuum, but they also unveil the kinematic structures of the flattened envelope. The dust continuum …

Understanding star formation at early stages in the filamentary era
… first investigate the importance of filamentary structures in star formation and propose an observationally driven scenario for the evolution of filamentary structures from large-scale molecular clouds to small-scale circumstellar envelopes. In addition, as theories of star formation have …

Evolution of the Circumstellar Atomic and Molecular Envelopes Around Evolved Stars
… well with the observed line intensities. The kinematics of the atomic gas are comparable to the molecular expansion velocities, expected for cooling lines associated with circumstellar PDRs. PDR mass estimates ranging from ∼0.01--1.3 M⊙ were derived from the [C II] 158 mum line …

A COMPARISON OF STAR FORMATION WITHIN THE GALACTIC CENTRE AND GALACTIC DISC
… such that the natal conditions of the gas – e.g. kinematics and chemistry – are not destroyed. Quiescent regions that are expected to form low-mass stars have been well studied over the past few decades, and the general process of low-mass star formation is well understood. Only relatively …

Sensorimotor Processes Underpinning Imitaiton Learning of Biological Motion
… to examine imitation of underlying movement kinematics. Across four experiments, imitation of the kinematic structures of biological and non-biological motion models was examined to investigate the processes involved in imitation learning. The purpose of the first experimental chapter, …
