Young stellar objects (YSOs) as a research area encompass the observational and theoretical study of stars in their early evolutionary phases, from deeply embedded protostars to pre-main-sequence stars such as T Tauri and Herbig Ae/Be objects. This field investigates accretion processes, circumstellar disks, jets and outflows, variability, and the interaction of YSOs with their natal molecular environments across multiple wavelengths (X-ray to radio). Research on YSOs constrains star formation efficiencies, timescales, initial mass functions, and disk evolution, providing critical boundary conditions for models of planet formation and feedback-regulated galactic star formation.
This month's NASA/ESA/CSA James Webb Space Telescope Picture of the Month offers us a two-for-one on brand new stars—with some potential planets thrown in as well. This visual highlights Webb's views of the protoplanetary ...

Russian astronomers from Moscow State University have performed photometric, polarimetric, and spectroscopic observations of a young star designated IRAS 21204+4913. Results of the new observations, which were published February ...
Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form and these "dirty snowballs" spend most of their ...

Young stars need time to grow into their final masses before they begin fusing lighter elements into heavier elements as main-sequence stars. They can spend hundreds of thousands of years as protostars, when they're still ...
