Constraining the volatile budget in the birthplace of TRAPPIST-1-like systems

JWST observations demonstrate that rocky planets around M dwarfs, such as those of TRAPPIST-1 system, have little or no atmosphere. The reason for this could be that they either have experienced significant atmospheric loss or that their initial volatile inventory was smaller. We propose to break this degeneracy by studying the volatile budget in the birthplaces of TRAPPIST-1-like systems. While many GO and GTO programs target the ice budget of solar-type protostars, the inventories of icy volatiles around very low luminosity protostellar systems, potential TRAPPIST-1 precursors, are vastly unexplored. Through the study of ices in 9 very low-luminosity protostellar systems across different star forming regions, we will examine whether there are any systematic differences in the initial volatile inventory between the very low luminosity systems and their higher luminosity counterparts.
