Estimation of Dust Mass from Infrared Emission and Extinction of Supernova Remnants: G93.7-0.2, G109.1-1.0, G156.2+5.7, and G166.0+4.3
Zhe Zhang, Jun Li, Biwei Jiang +1
Supernova remnants (SNRs) are major sites for both the production and destruction of interstellar dust, and quantifying their dust budget is essential for understanding the life cy…
JWST Reveals a Galaxy-Wide Association of Red Supergiants with OB Stars in NGC 5584
Min Dai, Shu Wang, Biwei Jiang
The spatial relationship between young and evolved massive-star tracers offers a means of probing recent star formation across galactic disks. We combine JWST/NIRCam, /UVOT…
Distance Determination of Southern Galactic Plane Supernova Remnants with the Mopra CO Survey and DECaPS 3D Dust Map
Fupeng Liu, He Zhao, Biwei Jiang +2
Accurate distance measurements to supernova remnants (SNRs) are crucial for understanding their physical properties, evolutionary processes, and role in the Galactic interstellar m…
Mapping the Galactic disk with the LAMOST and Gaia Red clump sample: VIII: Mapping the kinematics of the Galactic disk using mono-age and mono-abundance stellar populations
Weixiang Sun, Yang Huang, Han Shen +5
We present a comprehensive study of the kinematic properties of the different Galactic disk populations, as defined by the chemical abundance ratios and stellar ages, across a larg…
On Carbon Nanotubes in the Interstellar Medium
Qi Li, Aigen Li, B. W. Jiang +1
Since their discovery in 1991, carbon nanotubes (CNTs) -- a novel one-dimensional carbon allotrope -- have attracted considerable interest worldwide because of their potential tech…
On the Optical-to-Silicate Extinction Ratio as a Probe of the Dust Size in Active Galactic Nuclei
Z. Z. Shao, B. W. Jiang, Aigen Li
Dust plays a central role in the unification theory of active galactic nuclei (AGNs). Whether the dust that forms the torus around an AGN is tenth-m-sized like interstellar grai…
The Interstellar Oxygen Crisis, or Where Have All the Oxygen Atoms Gone?
Shu Wang, Aigen Li, B. W. Jiang
The interstellar medium (ISM) seems to have a significant surplus of oxygen which was dubbed as the "O crisis": independent of the adopted interstellar reference abundance, the tot…
Very Large Interstellar Grains as Evidenced by the Mid-Infrared Extinction
Shu Wang, Aigen Li, B. W. Jiang
The sizes of interstellar grains are widely distributed, ranging from a few angstroms to a few micrometers. The ultraviolet (UV) and optical extinction constrains the dust in the s…
Dust in the Local Group
Aigen Li, Shu Wang, Jian Gao +1
How dust absorbs and scatters starlight as a function of wavelength (known as the interstellar extinction curve) is crucial for correcting for the effects of dust extinction in inf…
A Tale of Three Mysterious Spectral Features in Carbon-Rich Evolved Stars: The 21 Micrometer, 30 Micrometer, and "Unidentified Infrared" Emission Features
Ajay Mishra, Aigen Li, B. W. Jiang
The mysterious "21 micrometer" emission feature seen almost exclusively in the short-lived protoplanetary nebula (PPN) phase of stellar evolution remains unidentified since its dis…
Physical Dust Models for the Extinction toward Supernova 2014J in M82
Jian Gao, B. W. Jiang, Aigen Li +2
Type Ia supernovae (SNe Ia) are powerful cosmological "standardizable candles" and the most precise distance indicators. However, a limiting factor in their use for precision cosmo…
A three dimensional extinction map of the Galactic Anticentre from multi-band photometry
B. -Q Chen, X. -W. Liu, H. -B. Yuan +8
We present a three dimensional extinction map in band. The map has a spatial angular resolution, depending on latitude, between 3 -- 9\,arcmin and covers the entire XSTPS-GAC s…
Universality of the Near-Infrared Extinction Law Based on the APOGEE Survey
Shu Wang, B. W. Jiang
Whether the near-infrared (NIR) extinction law is universal has been a long debated topic. Based on the APOGEE H-band spectroscopic survey as a key project of SDSS-III, the intrins…
Modeling the Infrared Interstellar Extinction
Shu Wang, Aigen Li, B. W. Jiang
How dust scatters and absorbs starlight in the interstellar medium (ISM) contains important clues about the size and composition of interstellar dust. While the ultraviolet (UV) an…
On Iron Monoxide Nanoparticles as a Carrier of the Mysterious 21 Micrometer Emission Feature in Post-Asymptotic Giant Branch Stars
Aigen Li, J. M. Liu, B. W. Jiang
A prominent, mysterious emission feature peaking at ~20.1 micrometer --- historically known as the ``21 micrometer' feature --- is seen in over two dozen Galactic and Magellanic Cl…
Unidentified species in envelopes around carbon stars
Biwei Jiang, Aigen Li, Ke Zhang +3
The infrared (IR) spectra of many evolved carbon-rich stars exhibit two prominent dust emission features peaking around 21um and 30um, with the former exclusively seen in proto-pla…
Modeling the Infrared Extinction toward the Galactic Center
Jian Gao, Aigen Li, B. W. Jiang
We model the ~1--19$\mum$ infrared (IR) extinction curve toward the Galactic Center (GC) in terms of the standard silicate-graphite interstellar dust model. The grains are taken to…
The Period-Luminosity Relation of Red Supergiant Stars in the Small Magellanic Cloud
Ming Yang, B. W. Jiang
The characteristics of light variation of RSGs in SMC are analyzed based on the nearly 8-10 year long data collected by the ASAS and MACHO projects. The identified 126 RSGs are cla…
Testing a pulsating binary model for long secondary periods in red variables
J. D. Nie, X. B. Zhang, B. W. Jiang
The origin of the long secondary periods (LSPs) in red variables remains a mystery up to now, although there exist many models. The light curves of some LSPs stars mimic an eclipsi…
