Herbig Ae/Be stars are a type of young, massive star that are still in the process of forming. They are typically found in star-forming regions and are characterized by their strong emission lines in their spectra, indicating the presence of gas and dust around them. These stars are more massive than the Sun, with masses ranging from about 2 to 8 times that of the Sun, and they are often surrounded by a protoplanetary disk. These stars are named after the astronomer George Herbig, who studied them in the 1960s, and Hernando Be, who contributed to the understanding of their properties. Herbig Ae/Be stars are important for studying stellar evolution and the formation of planetary systems, as they provide insights into the early stages of star life and the conditions that lead to planet formation.
