Red-giant branch the star when it reaches the horizontal branch, so the properties of red-clump stars can be used to determine the mass difference before and after the helium flash. Mass lost from red giants also determines the mass and properties of the white dwarfs that form subsequently. Estimates of total mass loss for stars that reach the tip of the red-giant branch are around . Most of this is lost within the final million years before the helium flash. Mass lost by more-massive stars that leave the red-giant branch before the helium flash is more difficult to measure directly. The current
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.
