On the Origin of the North Celestial Pole Loop
The Astrophysical Journal, 2023 The North Celestial Pole Loop (NCPL) provides a unique laboratory for studying the early-stage precursors of star formation. Uncovering its origin is key to understanding the dynamical mechanisms that control the evolution of its contents. In this study,

Diamonds and the Interstellar Extinction Curve [PDF]
Nature, 1970 IT has been suggested1 that the interstellar extinction might be explained by assuming that the interstellar dust is composed of an appropriate size distribution of diamond particles. The imaginary part of the index of refraction of diamond increases sharply from near zero to about 1.0 at λ−1 = 5.0 µm−1, giving an albedo near unity in the visible and ...

Interstellar Extinction of Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1993 We have compared the extinction of planetary nebulae (PN) as derived from the Balmer decrement and from the ratio of radio to Hβ fluxes.

Interstellar Extinction in the Gaia Photometric Systems
Open Astronomy, 2003 Three medium-band photometric systems proposed for the Gaia space mission are intercompared in determining color excesses for stars of spectral classes from O to M at V = 18 mag.

Structure in the Interstellar-Extinction Curve
The Astrophysical Journal, 1971 Using photographic techniques, it was attempted to obtain spectra of the interstellar material at a resolution of about 5 A. Three classes of structures are discussed. It is pointed out that the optical observations can be extended into the UV with a resolution of 0.4 A using the OAO-C telescope.

An All-sky 3D Dust Map Based on Gaia and LAMOST
The Astrophysical Journal Supplement SeriesWe present a comprehensive 3D dust-reddening map covering the entire Milky Way, constructed by combining reddening estimates based on Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST) low-resolution spectra ( E ( B − V ) _LAMOST ) with ...

Interstellar extinction toward symbiotic stars
, 2020 Using diffuse interstellar bands (DIBs) at 5780 A, 5797 A and 6613 A, visible in the high resolution spectra, and measuring their equivalent widths, we estimate the interstellar extinction toward seven symbiotic stars. We find $E_{B-V}$= $1.28 \pm 0.10$ for AS 289, $E_{B-V}$= $1.55 \pm 0.10$ for BI Cru, $E_{B-V}$= $0.63 \pm 0.10$ for HD330036, $E_{B-V}$

Probing the Distinct Extinction Law of the Pillars of Creation in M16 with JWST
The Astrophysical Journal LettersInvestigating the extinction law in regions of high dust extinction, such as the Pillars of Creation within the M16 region, is crucial for understanding the densest parts of the interstellar medium (ISM).
