Thanks to STFC & ERC funding, Profs Tami Rogers (Newcastle University, UK) and Conny Aerts (Leuven University, B) welcome applications for two postdoctoral positions of 3 years each to work on 3D hydrodynamical simulations of massive stars and their signature in modern observations and in 1D stellar models. The postdocs will work in close collaboration with the two PIs and with four PhD students (2 in Newcastle and 2 in Leuven).
