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…
