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…
Evidence of triggered star formation in the Pillars of Creation from JWST observations
Jing Wen, Bingqiu Chen, Jian Gao +3
Stars form in molecular clouds under the influence of their local environments, yet the role of massive stellar feedback in either triggering or suppressing star formation remains…
The First Glimpse of Water Ice Absorption Map in the Milky Way
Zhetai Cao, Biwei Jiang, Stefan Meingast
Interstellar ice plays a key role in the thermal evolution of the interstellar medium and in astrochemical pathways, yet its large-scale distribution remains poorly constrained. We…
Rotationally modulated highly circularly polarised radio pulses from the rapidly rotating M dwarf ASKAP J181335-604720
Shouzhi Wang, Biwei Jiang, Qichen Huang +2
We report the detection of strong, highly circularly polarised, and rotationally modulated radio pulses from the early-mid M dwarf ASKAP J181335-604720, based on strictly simultane…
The extinction distances for over a thousand planetary nebulae with Gaia measurements
Juan Deng, Shu Wang, Biwei Jiang +1
Although Gaia has identified the central stars of planetary nebulae (CSPNe) for about 70% of known Galactic planetary nebulae (PNe), reliable distance estimates remain incomplete,…
Identifying Red Supergiants in the Local Group Using JWST Photometry. I. NGC 6822, Sextans A, NGC 300, WLM, and IC 1613
Zhiwen Li, Ming Yang, Biwei Jiang +1
Red supergiants (RSGs) are crucial for studying the properties and evolution of massive stars. It is representative to conduct a census of RSGs across the Local Group, which spans…
Exploring the formation mechanisms of tidal structures in globular clusters of extragalactic origin
Shouzhi Wang, Jundan Nie, Biwei Jiang +3
Tidal structures around globular clusters provide valuable insights into cluster evolution and the hierarchical assembly of the Milky Way. Using wide-field imaging data from the DE…
The frequency-independent radio luminosity -- orbital/rotational period relation of RS CVn stars
Qichen Huang, Biwei Jiang
Radio emissions from RS CVn objects exhibit distinct characteristics at low and high frequencies, widely attributed to differing radiation mechanisms. The disparate processes of hi…
The Kinematic Signature of the Warp and Waves in the Milky Way Disk
Weixiang Sun, Han Shen, Biwei Jiang +1
Using over 170,000 red clump (RC) stars selected from LAMOST and APOGEE, we conduct a detailed analysis of the stellar as a function of (or ) across differen…
The Age-velocity Dispersion Relations of the Galactic Disk as Revealed by the LAMOST-Gaia Red Clump Stars
Weixiang Sun, Han Shen, Biwei Jiang +1
Using nearly 230,000 red clump (RC) stars selected from LAMOST and Gaia, we conduct a comprehensive analysis of the stellar age-velocity dispersion relations (AVRs) for various dis…
The Galactic Disk North-south Asymmetry in Metallicity May Be A New Tracer for the Disk Warp
Weixiang Sun, Han Shen, Biwei Jiang +1
Galactic disk warp has been widely characterized by stellar distributions and stellar kinematics but has not been traced by stellar chemistry. Here, we use a sample with over 170,0…
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…
On the chemical and kinematic signatures of the resonances of the Galactic bar as revealed by the LAMOST-APOGEE red clump stars
Weixiang Sun, Han Shen, Biwei Jiang +1
The Milky Way is widely considered to exhibit features of a rotational bar or quadrupole bar. In either case, the feature of the resonance of the Galactic bar should be present in…
Mapping the Chemo-dynamics of the Galactic disk using the LAMOST and APOGEE red clump stars
Weixiang Sun, Han Shen, Biwei Jiang +1
A detailed measurement is made of the metallicity distributions, kinematics and dynamics of the thin and thick disks, across a large disk volume (5.0 15.0 kpc and…
Exploring Be phenomena in OBA stars: a Mid-infrared search
Mingjie Jian, Noriyuki Matsunaga, Biwei Jiang +2
As early-type stars with a rotation speed close to their critical velocity, Be stars experience an event called the Be phenomenon. The material in their equator is ejected into out…
Estimation of the flux at 1450MHz of OB stars for FAST and SKA
Qichen Huang, Biwei Jiang, Dingshan Deng +2
Radio observation is crucial to understanding the wind mechanism of OB stars but very scarce. This work estimates the flux at 1450MHz () of about 5,000 OB stars ide…
Extinction of Taurus, Orion, Perseus and California Molecular Clouds Based on the LAMOST, 2MASS and Gaia surveys I: Three-dimensional Extinction and Structure
Zhetai Cao, Biwei Jiang, He Zhao +1
The three-dimensional extinction and structure are studied for the Taurus, Orion, Perseus and California molecular clouds based on the LAMOST spectroscopy. Stellar color excess is…
