| Abstract: | Stars form in regions of the galaxy that are denser and cooler than the mean interstellar medium. These regions are called
Giant Molecular Clouds. At the beginning of their life, up to 105–106 years, stars accrete matter from their rich surrounding environment and are origin of a peculiar phenomenon that is the jet
emission. Jets from Young Stellar Objects (YSOs) are intensively studied by the astrophysical community by observations at
different wavelengths, analytical and numerical modeling and laboratory experiments. Indications about the jet propagation
and its resulting morphologies are here obtained by means of a combined study of hypersonic jets carried out both in the laboratory
and by numerical simulations. |
