To reveal the origins of diffuse H-alpha emissions observed around the Herbigstar MWC 1080, we have performed a high-resolution near-infrared (NIR)spectroscopic observation using the Immersion GRating INfrared Spectrograph(IGRINS). In the NIR H and K bands, we detected various emission lines (sixhydrogen Brackett lines, seven H2 lines, and an [Fe II] line) and comparedtheir spatial locations with the optical (H-alpha and [S II]) and radio (13COand CS) line maps. The shock-induced H2 and [Fe II] lines indicate the presenceof multiple outflows, consisting of at least three, associated young stars inthis region. The kinematics of H2 and [Fe II] near the northeast (NE) cavityedge supports that the NE main outflow from MWC 1080A is the blueshifted onewith a low inclination angle. The H2 and [Fe II] lines near the southeastmolecular region newly reveal that additional highly-blueshifted outflowsoriginate from other young stars. The fluorescent H2 lines were found to tracephotodissociation regions formed on the cylindrical surfaces of the mainoutflow cavity, which are expanding outward with a velocity of about 10-15km/s. For the H-alpha emission, we identify its components associated with twostellar outflows and two young stars in addition to the dominant component ofMWC 1080A scattered by dust. We also report a few faint H-alpha featureslocated ~0.4 pc away in the southwest direction from MWC 1080A, which lie nearthe axes of the NE main outflow and one of the newly-identified outflows.
