The effects of metallicity on the evolution of protoplanetary disks may bestudied in the outer Galaxy where the metallicity is lower than in the solarneighbourhood. We present the VLT/KMOS integral field spectroscopy in thenear-infrared of $\sim$120 candidate young stellar objects (YSOs) in theCMa-$\ell$224 star-forming region located at a Galactocentric distance of 9.1kpc. We characterise the YSO accretion luminosities and accretion rates usingthe hydrogen Br$\gamma$ emission and find the median accretion luminosity of$\log{(L_{\rm acc})} = -0.82^{+0.80}_{-0.82} L_\odot$. Based on the measuredaccretion luminosities, we investigate the hypothesis of star formation historyin the CMa-$\ell$224. Their median values suggest that Cluster C, where most ofYSO candidates have been identified, might be the most evolved part of theregion. The accretion luminosities are similar to those observed towardlow-mass YSOs in the Perseus and Orion molecular clouds, and do not reveal theimpact of lower metallicity. Similar studies in other outer Galaxy cloudscovering a wide range of metallicities are critical to gain a complete pictureof star formation in the Galaxy.
