With the aim of characterizing the dynamical processes involved in the formation of young protostars, we present high angular resolution ALMA dust polarization observations of the Class 0 protostellar cores Serpens SMM1, Emb 8(N), and Emb 8. With spatial resolutions ranging from 150 to 40 au at 870 {\mu}m, we find unexpectedly high values of the polarization fraction along the outflow cavity walls in Serpens Emb8(N)... (read more)
