Unveiling Sibling Star Clusters in the Milky Way: New Advances in Systematic Identification and Classification

Researchers have carried out a large, systematic study of binary open clusters in the Milky Way.Stars usually form in clusters, and such clusters can also form in pairs or groups. Binary clusters (BCs), defined as pairs of open clusters closely associated both in position and kinematics. Their formation records how stars arise with...

Researchers reveal significant role of interstellar PAHs in molecular clouds

Researchers have made new progress in the study of polycyclic aromatic hydrocarbons (PAHs) in molecular clouds.Polycyclic aromatic hydrocarbons (PAHs) are important carriers of organic matter in the universe. They, as organic molecules, not only play a central role in interstellar chemistry but are also closely related to the origin of prebiotic ...

Formaldehyde Unravels New Insights into Star Formation in Cygnus-X

The researchers conducted deep observations of the 6-cm formaldehyde (H₂CO) absorption line and H110α recombination line toward the Cygnus-X region (∼9 deg²) using the NanShan 26-meter Radio Telescope. This work has produced the firs...The Cygnus-X region, as an important star-forming area within the Milky Way, has long been a focus of research concerning the physical conditions and dynamical evolution of its molecular cloud structures.In a recent study published in Mo...

Researchers Discover an End-Dominated Collapse and Hub-filament System in G53 Star-Forming Region

The researchers conducted a systematic study of the filamentary structure within the G53 molecular cloud. By combining multi-wavelength observations and simulations, they revealed for the first time that the filament is undergoing an "en...Recently, MENG Dezhao, a PhD student in the Star Formation and Evolution group at the Xinjiang Astronomical Observatory, Chinese Academy of Sciences, and his collaborators conducted a systematic study of the filamentary structure within ...
