![]() Observations of the very young star J160532 2Īnd its disc, carried out using the James Webb Space Telescope, have revealed a surprising abundance of hydrocarbons, some of which have even been detected for the first time ever in a disc. Working together within the MINDS consortium ( MIRI mid-Infrared Disk Survey) have partially lifted the veil on one of the mysteries that still surround protoplanetary discs, namely their chemical composition. Now, scientists from 11 European countries 1 However, this process remains poorly understood. Matter clumps together there, forming 'protoplanets' that continue to grow by accreting the material they encounter in the disc. Planets are born from the discs of dust and gas that form around a young star after its birth. 1With the CEA as lead funding agency and CNES as prime contractor, several French laboratories played a key role in delivering the MIRI imager: the Laboratoire Astrophysique, Instrumentation, Modélisation (CEA/CNRS/Université Paris Cité), the Institut d'Astrophysique Spatiale (CNRS/Université Paris-Saclay), the Laboratoire d'Études Spatiales et d'Instrumentation en Astrophysique (Observatoire de Paris-PSL/CNRS/Sorbonne Université/Université Paris Cité), and the Laboratoire d'Astrophysique de Marseille (CNRS/Aix Marseille Université).The findings, published on May 11 in the journal Nature Astronomy, were obtained using the MIRI instrument developed by a consortium of laboratories in Europe 1 Surprisingly, this is rich in hydrocarbons, two of which have even been detected in a protoplanetary disc for the first time ever. In recent years, observations have shown that rocky exoplanets are very abundant around low-mass stars such as J160532.Īn international research team including scientists from the CNRS, Université Paris-Saclay and the French Alternative Energies and Atomic Energy Commission CEA, supported by the French Space Agency CNES, has revealed the chemical composition of a disc of matter rotating around a young star, from which new planets are forming. The James Webb Space Telescope has revealed the chemical composition of the disc around the star J160532, which turns out to be rich in hydrocarbons. Young stars are surrounded by discs of material from which future planets form.
