Nobeyama Cygnus-X Survey: Physical Properties of C¹⁸O clumps in DR-6(W), DR-9 and DR-13S regions
Paper i proceeding, 2024

Cygnus-X is considered a region of interest for high-energy astrophysics, since the Cygnus OB2 association has been confirmed as a PeVatron in the Cygnus cocoon. In this research note, we present new high-resolution (16”) 12,13CO(J=1→0) and C18O (J=1→0) observations obtained with the Nobeyama 45-m radiotelescope, to complement the Nobeyama Cygnus-X Survey. We discovered 19 new C18O clumps associated with the star-forming regions DR-6W, DR-9, and DR13S. We present the physical parameters of these clumps, which are consistent with the neighboring covered regions. We confirm the clumpy nature of these regions and of a filament located between DR6 and DR6W. These results strongly suggest that star formation occurs in these regions with clumps of sizes ∼10−1 pc, masses ∼102 M☉, and H2 densities of ∼104 cm−3
