Fuenmayorhave found that massive stars’ ultraviolet radiation prevents the formation of giant planets in young systems by dispersing their building materials.
To find out how planetary systems such as our Solar System form, an international research team including scientists from the University of Cologne studied a stellar nursery, the Orion Nebula, using the. By observing a protoplanetary disc named d203-506, they discovered the key role massive stars play in the formation of planetary systems that are less than a million years old. The study, led by Dr.
“It is great that so many contributions from the team over the years, including the planning of the observations and the evaluation the data, are bearing fruit in the form of these results that represent a significant step forward in understanding the formation of planetary systems,” said Dr. Yoko Okada from the University of Cologne’s Institute of Astrophysics.
The JWST data in the Orion Nebula is very rich, keeping scientists busy to conduct various detailed analyses in the fields of star- and planet-formation as well as the evolution of the interstellar medium.
