Why is the OBAFGKM sequence important in astronomy?

The OBAFGKM sequence is crucial in astronomy as it classifies stars by their spectral type, which reflects their surface temperature and intrinsic properties. This classification helps astronomers understand the lifecycle, composition, and evolution of stars. Annie Jump Cannon's refined system provided a much-needed structure for decades of stellar research.
