Chemical differentiation in L1544, a prototypical prestellar core

Main Colloquium
Dr. Silvia Spezzano

Starless cores represent the initial conditions of star formation and they are the ideal laboratories to study physical and chemical processes away from the complications due to protostellar feedback. We have recently compared the spatial distribution of cyclopropenylidene, c-C3H2, and methanol in L1544 and underlined a different distribution among C-bearing species within the core. I will discuss the chemical differentiation in L1544 by using the maps of over 25 molecular tracers. I will also present the laboratory facilities at the Center for Astrochemical Studies at MPE, and highlight some recent results.
