We present deep HST/ACS observations of the G1 clump, a distinct stellar overdensity lying at ∼ 30 kpc along the south-western major axis of M31 close to the G1 globular cluster (Ferguson et al. 2002). Our well-populated colour-magnitude diagram reaches ∼7 magnitudes below the red giant branch tip with 90% completeness, and allows the detection of various morphological features which can be use...
Executive Summary The stellar Initial Mass Function (IMF) is remarkably consistent over a host of environments in the Galactic neighborhood. The physical processes responsible for producing a seemingly invariant IMF have long been the subject of theoretical investigation. Recently, a potential link has been made between the mass distribution of clumps in nearby molecular clouds and the stellar ...
We have performed smoothed particle radiation magnetohydrodynamics (SPRMHD) simulations of the collapse of rotating, magnetised molecular cloud cores to form protostars. The calculations follow the formation and evolution of the first hydrostatic core, the collapse to form a stellar core, the launching of outflows from both the first hydrostatic core and stellar cores, and the breakout of the s...
