Definition
A phase of stellar evolution where intermediate-mass stars burn helium in their cores while maintaining relatively constant luminosity. These stars appear as a horizontal band on the Hertzsprung-Russell diagram of globular clusters.
Etymology
Named for the horizontal appearance of these stars on color-magnitude diagrams of star clusters, first identified in the 1950s. The term 'branch' refers to the branching paths of stellar evolution tracks on the H-R diagram.
Kelly Says
Horizontal branch stars are stellar time machines that help us determine the ages of the oldest star clusters in our galaxy! The precise temperature and color distribution of these helium-burning stars can reveal whether a globular cluster is 12 or 13 billion years old - crucial for understanding when the first stars formed.
