(Phys.org)—Astronomers have recently presented new results of observations of a nearby planetary system known as 61 Virginis (or 61 Vir for short). The observations were focused on investigating the system's debris disk, ...
By examining the atomic carbon line from two young star systems—49 Ceti and Beta Pictoris—researchers had found atomic carbon in the disk, the first time this observation has been made at sub-millimeter wavelength, hinting ...
