In the MK system, this type of star corresponds to class V. An important characteristic that definesthese stars is chemical homogeneity.
In the MK system, this type of star corresponds to class V. An important characteristic that definesthese stars is chemical homogeneity. One way to determine the distance to a cluster is to vertically fit thesetype of stars on a CMD, which gives one the distance modulus. The age of a cluster can be determined bythe age of this type of star at the turnoff point. "Zero age" is the point at which a star evolves from aprotostar into this type of star. On a Hertzsprung-Russell diagram, stars on this track proceed along thediagonal from bottom right to top left in the area of highest density. For 10 points, given this term for starsthat obtain their energy by fusing hydrogen to create helium in their core.
