Abstract
The Multipupose InfraRed Imaging System (MIRIS) Paα Galactic Plane Survey (MIPAPS) covers the whole Galactic plane with the latitude range of -3° < b < +3°. Next to the first result in l = 96°-116° (Cepheus), we present the results in l = 276°-296° (Carina). This region with the direction toward the inner Galaxy, has much higher extinction but much more Paα-emitting sources than Cepheus. We list up the detected Paα sources, and compare them with the WISE H II region catalog (there are 308 H II regions and candidates in this region) and VPHAS+ Hα image. By detecting the Paα and Hα recombination lines, 71 H II region candidates are newly confirmed as definite H II regions, out of which 53 H II regions are detected at Paα. For the Paα-detected sources, we measure the Paα and Hα fluxes and estimate the E(B-V) color excesses for the extended sources.
