- Oph-IRS 48 est une jeune étoile similaire au Soleil qui se situe dans le nuage de Rho Ophiuchi (constellation d'Ophiuchi) . Elle a été premièrement identifiée par le satellite IRAS comme une source infrarouge très puissante. Selon la mesure annuelle de sa parallaxe par le satellite Gaia, elle se situe à 444 années-lumière de la Terre. (fr)
- Oph-IRS 48 is a star surrounded by an extraordinary protoplanetary disk, about 444 light-years from Earth in the constellation of Ophiuchus.The disk has revolutionized the view of planet formation in astronomy. Studies have shown that the millimeter dust particles are gathered in a crescent shape, while the gas (traced by CO molecules) and small dust grains follow a full disk ring structure . The centimeter grains are even more concentrated inside the crescent. This structure is consistent with theoretical predictions of dust trapping. Also the chemical composition has been studied, with molecules like H2CO being present. The dust trap is thought to be conducting the process of planet formation in this young system. (en)
