Red-giant branch branch (SB), and red-giant branch (RGB), for stars with different initial masses, all at solar metallicity (Z = 0.02). Also shown are the helium core mass, surface effective temperature, radius, and luminosity at the start and end of the RGB for each star. The end of the red-giant branch is defined to be when core helium ignition takes place. Intermediate-mass stars only lose a small fraction of their mass as main-sequence and subgiant stars, but lose a significant amount of mass as red giants. The mass lost by a star similar to the Sun affects the temperature and luminosity of
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.
