In the residual disk around an F-class star, scientists have recorded carbon monoxide for the first time.
This is reported by scientists at the European Southern Observatory ESO (European Southern Observatory) on its official website.
It is reported that the discovery was made with the ALMA telescope, which is located at an altitude of 5 kilometers on the Chahnantor plateau in Chile.
Experts have recorded carbon monoxide in the residual disk around the star HD 181327, which is part of the moving group Beta Painter and is located about 170 light-years from the Sun.
According to experts, up to this point, carbon dioxide molecules were found exclusively near class A stars, which are much more massive and brighter.
Scientists note that it was possible to see a faint nebulous ring around the star HD 181327 and map the CO density distribution in the disk due to the high spatial resolution and sensitivity of the ALMA telescope.
It should be added that the study of residual disks is very important for scientists, since this is one of the main ways to establish the mechanisms of formation of planets and planetary systems.
