Today in the Milky Way, star formation typically occurs in low-mass environments. Young star clusters (e.g., younger than 10 million years), in fact, typically have a mass of a few hundred solar masses. Nevertheless, our Galaxy hosts a few very massive star-forming regions that can produce tens to hundreds of thousands of stars, including some of the most massive stars

Ices and X-rays to explain chemical abundances in protoplanetary disks. The study: “X-ray processing of a realistic ice mantle can explain the gas abundances in protoplanetary disks” of A. Ciaravella (INAF-OAPA) recently appeared on PNAS

To understand how planets form, it is mandatory to study the evolution of protoplanetary disks, e.g. disks of gas and dust grains orbiting around stars during the first 3-5 million years of their evolution, a that may evolve into planetary systems. In the last years, several observations have been done in order to detect the molecules, mainly organic, in these
