Herbig Ae/Be stars are a type of young, massive stars that are still in the process of forming. They are characterized by their spectral types, which range from A to B, indicating they are hotter and more luminous than the Sun. These stars are often surrounded by a disk of gas and dust, which can lead to the formation of planets. These stars are important for studying stellar evolution and the formation of planetary systems. They exhibit strong emission lines in their spectra, indicating ongoing accretion of material from their surrounding environment. Herbig Ae/Be stars are typically found in star-forming regions, providing insights into the early stages of star life.
