Red giant causing helium in a shell to begin fusing. At the same time hydrogen may begin fusion in a shell just outside the burning helium shell. This puts the star onto the asymptotic giant branch, a second red-giant phase. The helium fusion results in the build up of a carbon–oxygen core. A star below about will never start fusion in its degenerate carbon–oxygen core. Instead, at the end of the asymptotic-giant-branch phase the star will eject its outer layers, forming a planetary nebula with the core of the star exposed, ultimately becoming a white dwarf. The ejection of the outer mass
Southern Star Central Gas Pipeline FERC code is 43. The company was formed in 1904. In 1926, it was renamed Cities Service Gas Company. It was again renamed in 1982 to the Northwest Central Pipeline Corporation. Five years later it took the name Williams Natural Gas Company. In 1997, it was reorganized and called the Williams Gas Pipeline Central, Inc. In 2003, it was renamed the Southern Star Central Gas Pipeline, Inc. Southern Star's Central Pipeline brings gas from the Rocky Mountains, Texas, and Oklahoma to Kansas. From there it goes east to Missouri.
