The dynamic centres of infrared-dark clouds and the formation of cores

Andrew J. Rigby, Nicolas Peretto, Michael Anderson +7

High-mass stars have an enormous influence on the evolution of the interstellar medium in galaxies, so it is important that we understand how they form. We examine the central clum…

Non-Equilibrium Abundances Treated Holistically (NEATH): the molecular composition of star-forming clouds

F. D. Priestley, P. C. Clark, S. C. O. Glover +4

Much of what we know about molecular clouds, and by extension star formation, comes from molecular line observations. Interpreting these correctly requires knowledge of the underly…

Line emission from filaments in molecular clouds

F. D. Priestley, D. Arzoumanian, A. P. Whitworth

Filamentary structures are often identified in column density maps of molecular clouds, and appear to be important for both low- and high-mass star formation. Theoretically, these…

Differences in chemical evolution between isolated and embedded prestellar cores

F. D. Priestley, A. P. Whitworth, E. Fogerty

Models of prestellar cores often assume that the cores are isolated from their environment - material outside the core boundary plays no role in the subsequent evolution. This is u…
