MWC 480 is a young star about twice the mass of the Sun located 455 light-years away in the Taurus star-forming region.[1] The name refers to the Mount Wilson Catalog of B and A stars with bright hydrogen lines in their spectra.[2]

MWC 480 has X-ray emissions typical of a pre-main-sequence Herbig Ae/Be star but with an order of magnitude more photoelectric absorption.[3] It has a gas-dust envelope and is surrounded by a protoplanetary disc. Astronomers using the ALMA (Atacama Large Millimeter/submillimeter Array) have found that the protoplanetary disc surrounding MWC 480 contains large amounts of methyl cyanide (CH3CN), a complex carbon-based molecule.[4] Hydrogen cyanide (HCN) has also been detected in the disc.[5] No signs of planet formation have yet been detected.
