Differential Reddening and Extinction Law Analyses of Galactic Open Clusters

Xiaohan Chen, Shu Wang, Xiaodian Chen

Extinction significantly affects open cluster parameters and their use in studies of Galactic structure, yet homogeneous large sample measurements of open cluster extinction proper…

Divergent Evolution of Radial Metallicity Gradients in the Thin and Thick Disks of the Milky Way

Weixiang Sun, Gaohuan Long, Hui Li +6

Using 200,388 red clump stars from LAMOST and APOGEE, we investigate the radial metallicity gradients of the Galactic disk as a function of vertical height and stellar age. The thi…

Euclid Q1 reveals spatial variations of the extinction law in the dense cloud LDN 1641

Rui Chen, Shu Wang, Xiaodian Chen +1

Dust extinction laws are essential for precision photometry and provide a direct probe of grain properties, but their behaviour in dense molecular clouds remains poorly constrained…

Extinction of Taurus, Orion, Perseus and California Molecular Clouds Based on the LAMOST, 2MASS, and Gaia Surveys II: The Extinction Law

Zhetai Cao, Biwei Jiang, Shu Wang +1

The extinction law from ultraviolet (UV) to infrared (IR) (0.2-24 m) is determined by relying on the blue-edge method and color excess ratios for some nearby molecular clouds, f…

The Optical to Infrared Dust Extinction Law of the Milky Way with JWST NIRSpec: Westerlund 2

Shu Wang, Xiaodian Chen

The interstellar extinction law is important for interpreting observations and inferring the properties of interstellar dust grains. Based on the 993 prism/CLEAR spectra from the J…

Tracing the Galactic disk from the kinematics of Gaia Cepheids

Xiaoyue Zhou, Xiaodian Chen, Licai Deng +1

Classical Cepheids (CCs) are excellent tracers for understanding the structure of the Milky Way disk. The latest Gaia Data Release 3 provides a large number of line-of-sight veloci…
