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

The Astronomical Journal
The extinction law from ultraviolet (UV) to infrared (IR; 0.2–24 μ m) is determined by relying on the blue-edge method and color-excess ratios for some nearby molecular clouds, from the low-mass star-forming region to the massive star-forming region. The

The interstellar extinction to V4334 Sgr (Sakurai's object)

, 2002
We present an 8–13$~\mu$m spectrum of V4334 Sgr (Sakurai's object), which shows clear evidence for the presence of a silicate absorption feature at 9.7$~\mu$m.

Interstellar Reddening of Type Ia Supernovae

, 2006
We re-investigate the Lira-Phillips relation of Type Ia supernovae and its use for determination of reddening of individual SNe Ia. We use a more recent, more extensive dataset of SNe Ia with negligible reddening, and attempt to refine the prediction of ...

On the nature of high reddening of Cygnus OB2 #12 hypergiant [PDF]

, 2016
© 2016 The Authors.To explain the nature of the high reddening (AV ≃ 10 mag) towards one of the most luminous stars in the Galaxy - Cyg OB2 #12 (B5 Ia-0), also known as MT304, we carried out spectrophotometric observations of 24 stars located in its ...

Interstellar Reddening in the Local Bubble and Loop I Region: Insight from Strömgren Photometry Analysis and Three-dimensional Modeling

, 2011
The Sun is located inside an extremely low density region called the Local Bubble (LB). Although they have been studied through a large variety of techniques, the contours of its neutral boundary, defined by a dense wall of interstellar gas and dust, are

Interstellar Comet 3I/ATLAS: Evidence for Galactic Cosmic-Ray Processing

The Astrophysical Journal Letters
Spectral observations of 3I/ATLAS (C/2025 N1) with JWST/NIRSpec and SPHEREx reveal an extreme CO _2 enrichment (CO _2 /H _2 O = 7.6 ± 0.3) that is 4.5 σ above solar system comet trends and among the highest ever recorded.
