Astrophysics

Main sequence

A diagonal band on an H–R or color–magnitude diagram running from upper left to lower right, representing the stellar main sequence. Depict it as a narrow to moderately broad continuous strip or dense streak of many small star-like plotted points, forming a smooth slightly curved sloping locus across a rectangular chart area. The stars or band transition in color from hot blue-white at the upper left through yellow toward red or red-orange at the lower right. The band should read as the dominant stellar sequence, with clean smooth edges or slight transparency if rendered as a shaded strip. Use a clean scientific infographic style with thin crisp lines, soft minimal shading, and a restrained luminous color palette.
