On the secular evolution of the ratio between gas and dust radii in protoplanetary discs

ABSTRACT A key problem in protoplanetary disc evolution is understanding the efficiency of dust radial drift. This process makes the observed dust disc sizes shrink on relatively short time-scales, implying that discs started much larger than what we see now. In this paper, we use an independent con...
