Stochastic histories of dust grains in the interstellar medium [PDF]

open access: yes, 1989
The purpose is to study an evolving system of refractory dust grains within the Interstellar Medium (ISM). This is done via a combination of Monte Carlo processes and a system of partial differential equations, where refractory dust grains formed within ...

The dust extinction curves of gamma-ray burst host galaxies

open access: yes, 2011
The composition and amount of interstellar dust within gamma-ray burst (GRB) host galaxies is of key importance when addressing selection effects in the GRB redshift distribution, and when studying the properties of their host galaxies.

Relationships between dust grain components responsible for observed interstellar extinction and polarization [PDF]

open access: yes, 1986
Ultraviolet extinction properties of interstellar dust are well observed. The amount of extinction measured in the visible (E(B-V)), at the 2200 A feature (E(BUMP)), and in the far ultraviolet (E(1550-V)) are only vaguely correlated indicating that at ...

Time Evolution of Optical Darkness in Gamma-Ray Burst Afterglow: The Case of GRB 240825A

open access: yesThe Astrophysical Journal
Long-duration gamma-ray bursts (GRBs) are believed to occur in star-forming regions. The multiwavelength follow-up observations of the early afterglow of GRB 240825A provided insights into the evolution of the optical-to-X-ray spectral feature of the ...

Silicate Extinction Profile Based on the Stellar Spectrum by Spitzer/IRS

open access: yesThe Astrophysical Journal
The 9.7 and 18 μ m interstellar spectral features, arising from the Si–O stretching and O–Si–O bending modes of amorphous silicate dust, are the strongest extinction features in the infrared.

NanoSIMS-Analyse und hochauflösende Elektronenmikroskopie an präsolaren Silikaten aus roten Riesensternen und Supernovaexplosionen [PDF]

open access: yes, 2009
This thesis deals with the analysis of “presolar” silicates and oxides by high resolution mass spectrometry and electron microscopy techniques. This “stardust” was identified by its extreme oxygen isotopic anomalies, which point to nucleosynthetic ...

Diverse reddening distributions in sight lines for type Ia supernovae

open access: yesAstronomy & Astrophysics
Context. Accurate cosmological constraints from type Ia supernovae (SNe) require sufficiently accurate corrections for host-galaxy extinction. Modelling these corrections is challenged by the problem of disentangling the SN’s intrinsic colours from host ...
