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.
A team of astronomers led by Paulo Cortes, a scientist with the U.S. National Science Foundation National Radio Astronomy Observatory and the Joint ALMA Observatory, have made a groundbreaking discovery about how young star ...

Astronomers from Argentina and Spain have performed near-infrared observations of a massive young stellar object known as MYSO G29.862−0.0044. The observational campaign sheds more light on the nature of this object and its ...
Astronomers have observed an explosion in space that is pushing back against and influencing the baby star which triggered the explosion in the first place. If explosions like this one are common around young stars, then ...

In 2015, astronomer Tabetha Boyajian and colleagues announced the discovery of unusual light fluctuations coming from a star about 1,500 light-years away. It came to be known as "Tabby's star" or "Boyajian's star," and the ...
