Major part of ‘planetary’ Ar, Kr, and Xe. These components (labeled Ar-Q, Kr-Q, and Xe-Q) usually dominate Ar, Kr, and Xe in primitive meteorites. Q gases are isotopically heavier than Supersonic flow of high-speed charged particles continuously blowing off a star (mostly e- and p+). When originating from stars other than the Sun, it is sometimes called a "stellar" wind. The solar wind may be viewed as an extension of the corona into interplanetary space. The solar wind emanates radially gases and are most likely of ‘local’ origin (probably trapped in the The primitive gas and dust cloud around the Sun from which planetary materials formed. by an ill-defined carbonaceous carrier ‘phase Q’).
