Molecular line profiles as diagnostics of protostellar collapse: modelling the `blue asymmetry' in inside-out infall
Y. G. Tsamis, J. M. C. Rawlings, J. A. Yates +1
The evolution of star-forming core analogues undergoing inside-out collapse is studied with a multi-point chemodynamical model which self-consistently computes the abundance distri…

Chemically inhomogeneous photoionization modelling of the planetary nebula SMC N87
Y. G. Tsamis, D. Pequignot
We present results from dual-abundance photoionization modelling of the planetary nebula SMC N87 (SMC-SMP 27). The models succesfully resolve the observed discrepancy between the h…
