Young Stellar Objects
Young Stellar Objects (YSOs) are stars in their earliest stages of evolution. Just as our Solar System once began as a cloud of dust and gas, these objects form through gravitational collapse. Think of them as "stellar babies" surrounded by a protoplanetary disk. These disks are similar to Saturn's rings but on a much vaster scale. YSOs often eject powerful jets of gas as they struggle to stabilize and ignite thermonuclear fusion. It is a critical phase that determines whether they will become a brilliant star like our Sun or remain hidden within their dusty cocoons.
- Percentage of Young Stellar Objects within 98.5 light years: 0.02 % (2 from 9522 stars)
- Average mass of Young Stellar Objects: 10-200% solar mass
- Average radius of Young Stellar Objects: 50-300% solar radius
- Average temperature of Young Stellar Objects: 2000-10000 K

Protoplanet candidate EK Chamaeleontis b identified around a young red dwarf star
9. 10. 2026
Stars | Exoplanets | Young Stellar ObjeThe search for planets in the very early stages of their formation, known as protoplanets, remains a significant challenge in space observation. A new candidate, designated as EK Cha b, has been observed around the young red dwarf star EK Cha. This object is notable because it provides a rare opportunity to study planetary development within a gas-rich environment. While large gas planets are less common around red dwarf stars compared to larger stars, these cool, small stars represent a common ...

6. 10. 2026Stars | Exoplanets | Young Stellar ObjeAn inclined planet orbiting HD 139614 is warping its protoplanetary disc, casting large shadows across the outer regions. New models confirm these shadows and a spiral structure are evidence of the planet's gravitational influence on the surrounding dust....
26. 9. 2026Stars | Exoplanets | Young Stellar ObjeNew mass measurements of the infant planets orbiting V1298 Tau reveal that planets b and e are likely gas giants. These findings, based on long-term radial velocity monitoring, suggest higher masses than previously estimated from transit timing observations....
9. 9. 2026Stars | Exoplanets | Young Stellar Objects | Planet formatioThe binary system DQ Tau shows that stellar accretion and X-ray activity directly influence its planet-forming disk. Observations reveal that these energy fluctuations shift the disk snowline and change the chemical emission of molecules like water and carbon dioxide....
1. 8. 2026Stars | Exoplanets | Young Stellar Objects | Planet formatioCQ Tauri exhibits a complex disk structure with a 25-AU cavity and a dust ring at 53 AU. Simulations suggest that while a Red dwarf companion could explain the inner gap, a massive planet in an outer orbit better matches the observed ring position....
