Из-за пандемии, конференция в 2020 году переведена в формат еженедельных онлайн семинаров, продолжительностью с октября 2020 - апрель 2021. How do stars form from gas? This question lies at the heart of astrophysics, as star formation is the key process governing the evolution of baryons. Star formation converts interstellar matter into stars and their planetary systems, depletes galaxies of gas, and feeds back metals, energy, and momentum into the interstellar medium, which may reach the halos of galaxies and beyond. In turn, this feedback, together with galactic-scale inflows and dynamics, impacts the state of the gas and the future of star formation. With new observational data and highly improved simulations, it is becoming clear that scaling relations commonly used for, e.g., the star formation process, star formation synthesis models, feedback models etc. are no longer sufficient. Progress needs to take into account how the environment present within galaxies may connect to the small-scale physics of the star formation process. Further observations at cloud-scales, for example, could inform our understanding of the physics acting in galaxies out to cosmic noon and implemented in state-of-the-art simulations. This workshop aims to bring together experts on the observation and theory of the star formation process to discuss the current state-of-the-field and identify promising ways forward to address pressing questions. The workshop hopes to follow the spirit of the 2013 Ringberg meeting on “Regulation of star formation in molecular gas: from galactic to sub-cloud scales”.
