New Candidate Massive Clusters from 2MASS [PDF]

, 2013
Massive stars are important for the evolution of the interstellar medium. The detailed study of their properties (such as mass loss, rotation, magnetic fields) is enormously facilitated by samples of these objects in young massive galactic star clusters.

High spatial resolution galactic 3D extinction mapping with IPHAS [PDF]

, 2008
We present an algorithm (MEAD, for 'Mapping Extinction Against Distance') which will determine intrinsic (r' - i') colour, extinction, and distance for early-A to K4 stars extracted from the IPHAS r'/ i'/H alpha photometric data base.

Turbulence in the interstellar medium [PDF]

, 2014
Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...

Interstellar Extinction [PDF]

Astrophysics, 2016
This review describes our current understanding of interstellar extinction. This differ substantially from the ideas of the 20th century. With infrared surveys of hundreds of millions of stars over the entire sky, such as 2MASS, SPITZER-IRAC, and WISE, we have looked at the densest and most rarefied regions of the interstellar medium at distances of a ...

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 ...

Evolving interstellar extinction [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
Interstellar dust containing carbon will necessarily have optical constants that respond to the local environment of the dust. This response may be sufficiently slow that the extinction produced by such dust may change on time-scales that are comparable to the likely cloud age.

An R V Map of the Milky Way Revealed by LAMOST

The Astrophysical Journal Supplement Series, 2023
The total-to-selective extinction ratio, R _V , is a key parameter for tracing the properties of interstellar dust, as it directly determines the variation of the extinction curve with wavelength.

Measurements of Interstellar Extinction [PDF]

Symposium - International Astronomical Union, 1989
The results of interstellar extinction measurements from the near IR to the far-UV are reviewed. The average interstellar extinction curve for the diffuse cloud medium exhibits a nearly linear rise (in 1/λ) from 1 μm−1 to the 2.25 μm−1 “knee” in extinction where the slope changes.
