Title： Properties of molecular cloud in the outer Milky Way
Abstract：
Understanding the origin of stellar initial mass function (IMF) is a central issue in the study of star formation. The past studies of dense cores reported that the slope of the stellar IMF and core mass function (CMF) are consistent, suggesting that the fundamental mass distribution of stars is determined during the early stage of the core formation. However, dense cores have been observed and studied only in the inner part of the Galactic plane (including the solar neighborhood), which has similar metallicity to that of the solar neighborhood. Thus, an important question to address is whether the same relation between the CMF and stellar IMF holds true even in low-metallicity environments. To solve this question, we performed CO and dust continuum ALMA high-resolution (~0.1 pc scale) mapping observation toward a massive star-forming molecular cloud in the outer Galaxy, which has much lower gas density and lower metallicity (~20 % of the solar neighborhood value) than those in the solar neighborhood . As a result, we successfully detected ~0.1 pc-wide filament structures and ~ 0.1 pc-scale dense core structures in the outer Galaxy for the first time. We found that the properties of the filaments and dense cores are similar to those in the solar neighborhood. We also found that the slope of the CMF in the outer Galaxy is similar to that of the universal IMF. These results suggest that the star formation processes in the low-metallicity environment follow a universal law.
