The spiral structure in the solar neighborhood is an important issue in astronomy. In the past few years, there has been significant progress in observation. The distances for a large number of good spiral tracers, i.e., giant molecular clouds, high-mass star-formation region masers, HII regions, O-type stars, and young open clusters, have been accurately estimated, making it possible to depict the detailed properties of nearby spiral arms. In this work, we first give an overview about the…

New Open-cluster Candidates Found in the Galactic Disk Using Gaia DR2/EDR3 Data
We report 541 new open-cluster candidates in Gaia EDR3 through revisiting the cluster results from an earlier analysis of Gaia DR2, which revealed nearly 1000 open-cluster candidates in the solar


Evolution of the local spiral structure of the Milky Way revealed by open clusters
The structure and evolution of the spiral arms of our Milky Way are basic but long-standing questions in astronomy. In particular, the lifetime of spiral arms is still a puzzle and has not been well
The local spiral structure of the Milky Way
Observed regions of massive star formation near the Local spiral arm of the Milky Way reveal that the Local Arm is larger than previously thought, and both its pitch angle and star formation rate are comparable to those of the Galaxy’s major spiral arms, such as Sagittarius and Perseus.
The spiral structure of the Milky Way
The morphology and kinematics of the spiral structure of the Milky Way is a long-standing problem in astrophysics. In this review we firstly summarize various methods with different tracers used to
The spiral structure of the Galaxy revealed by CS sources and evidence for the 4:1 resonance
We present a map of the spiral structure of the Galaxy, as traced by molecular carbon monosulphide (CS) emission associated with IRAS sources which are believed to be compact H ii regions. The CS
The spiral structure of our Galaxy— A review of current studies
The Galactic spiral structure as revealed by O- and early B-type stars
We investigate the morphology and kinematics of the Galactic spiral structure based on a new sample of O- and early B-type stars. We select 6,858 highly confident OB star candidates from the combined
Search for age pattern across spiral arms of the Milky Way
The age pattern across spiral arms is one of the key observational features utilised to study the dynamic nature of the Galaxy’s spiral structure. With the most updated samples of high-mass star
The Distribution of Open Clusters in the Galaxy
In this work we explore the new catalog of galactic open clusters that became available recently, containing 1,750 clusters that have been re-analyzed using the Gaia DR2 catalog to determine the
Towards a census of the Galactic anticentre star clusters – III. Tracing the spiral structure in the outer disc
In this paper we investigate the nature of 27 star cluster candidates, most of them projected towards the Galactic anticentre. We derive fundamental parameters for 20 confirmed clusters, among these
The bar and spiral arms in the Milky Way: structure and kinematics
The Milky Way is a spiral galaxy with the Schechter characteristic luminosity L∗, thus an important anchor point of the Hubble sequence of all spiral galaxies. Yet the true appearance of the Milky
