Unless you have a critical mass of heavy elements when your star first forms, planets, including rocky ones, are practically impossible.

Telltale twist points to the birth of a baby alien world Scott Sutherland mardi, 26 mai 2020 à 08:45 - Astronomers spotted signs of brand new exoplanet forming around another star. Astronomers have made another stride forward in their quest to image the birth of a planet around another star directly. For decades, scientists have been developing the basic ideas about how planets form around stars. First, a star forms from a collapsing cloud of gas and dust. The remaining material surrounding t...

14:00 If you have a question about this talk, please contact Dr Can Cui. The building blocks of planets are the dust, gas, and ice in the protoplanetary disks orbiting young stars. Deep, high resolution images of protoplanetary disks by ALMA have revealed complex and varied ring and spiral structures in a number of systems. In the Disk Substructures at High Angular Resolution Project (DSHARP), we undertook the first high angular resolution disk survey at millimeter wavelengths. DSHARP found...
