Carbon grains around evolved stars

Stardust, an ultra-high vacuum machine built in the project Nanocosmos ERC, was specifically conceived to simulate, with a high level of control, the complex conditions of stardust formation and processing in the environment of evolved stars. In addition, the AROMA setup was built to analyse the molecular content of the samples synthesized by Stardust. In … Read more

Gas ‘waterfalls’ reveal infant planets around young star

The birthplaces of planets are disks made out of gas and dust. Astronomers study these so-called protoplanetary disks to understand the processes of planet formation. Beautiful images of disks made with the Atacama Large Millimeter/submillimeter Array (ALMA) how distinct gaps and ring features in dust, which may be caused by infant planets. To get more … Read more

A second planet in the Beta Pictoris system

A team of astronomers led by Anne-Marie Lagrange, a CNRS researcher at the Institut de Planétologie et d’Astrophysique de Grenoble (CNRS/Université Grenoble Alpes)1, has discovered a second giant planet in orbit around β Pictoris, a star that is relatively young (23 million years old) and close (63.4 light years), and surrounded by a disk of … Read more
