Quantification of the radial redistribution as a function of the break strength (β), defined as hin−hout. Left-hand, top panel: mass fraction of accreted stars currently located in the outer region with respect to the total stellar mass in that region (γacc/tot,out) as a function of β. Right-hand, top panel: mass fraction of stars coming from inner radius with respect to the stellar mass of accreted stars currently located in the outer region (γout/acc,out) as a function of β. Left-hand, bottom panel: mass fraction of “in situ” stars in the whole galaxy with respect to the total mass of the galaxy (γinsitu/tot) as a function of β. Right-hand, bottom panel: mass fraction of stars currently located in the inner region with respect to the stars born in the same inner region (γcurrent/birth,in). Green points represent type-I galaxies, blue points are type-II galaxies and type-III systems are denoted by red points. Zeus is represented by a green diamond as it is a type-I galaxy with signs of ongoing interaction. See text for details.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
