MWC 480

[8] The name refers to the Mount Wilson Catalog of B and A stars with bright hydrogen lines in their spectra.

[4] 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.

[4] It has a gas-dust envelope and is surrounded by a protoplanetary disc that is about 11% the mass of the Sun.

[5] 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.

In 2021, an imaging of the gas flows in the circumstellar disk has suggested a presence of shrouded Jupiter-mass planet about 245 AU from the star.
