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.
An international team of scientists led by astronomers from the University of Wisconsin–Madison has produced the most accurate measurement of the gases swirling around young stars and how their mass changes over time. The ...

Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have detected water ice in a debris disk around HD 181327—a young star located within 160 light years away from the ...
Using various ground-based and space telescopes, an international team of astronomers has observed a highly variable young star known as DR Tauri. Results of the observational campaign, published May 12 on the arXiv preprint ...
In this image, the NASA/ESA Hubble Space Telescope peers into the spiral galaxy NGC 1317 in the constellation Fornax, located more than 50 million light-years from Earth. Visible in this galaxy image is a bright blue ring ...

Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system.

Using the NOrthern Extended Millimeter Array (NOEMA) and the Atacama Large Millimeter/submillimeter Array (ALMA), Chinese astronomers have observed a young stellar object known as G24.33+0.14 in the process of cooling after ...
Many protoplanetary disks in which new planets are formed are much smaller than thought. Using the Atacama Large Millimeter/submillimeter Array (ALMA) scientists of the Leiden Observatory (the Netherlands) looked at 73 protoplanetary ...
