horizontal branch star		which takes place primarily within the core	from the point of view of Earth		or center of gravity	greater than 1000 Kelvin	hydrogen, helium			which depends on luminosity class				star catalog	metal-poor star	weak	from the point of view of Earth's orbit		determined from proper motion and radial velocity	which is diffused out from the hotter core	extends shortward from the asymptotic branch at an approximately constant absolute bolometric magnitude of about 0.3				greater than 0.08 the sun's mass		A metal-poor star after it has undergone the helium flash and begins to quietly burn helium into carbon and oxygen in its core and hydrogen in a surrounding envelope.			blue to yellow		gravitational contraction and or fusion
