The Astronomical Journal, 2023 Optical starlight can be partially polarized while propagating through the dusty, magnetized interstellar medium (ISM). The polarization efficiency describes the polarization intensity fraction per reddening unit, P _V / E ( B − V ), related to the ...

Diverse reddening distributions in sight lines for type Ia supernovae
Astronomy & AstrophysicsContext. 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 ...

Presumed Detection of C5 Molecule in the Interstellar Medium
The Astrophysical Journal, 2022 The paper suggests the presence of the carbon chain C _5 molecule in translucent, interstellar H i clouds. This species, the only five atom interstellar molecule, observable in dark, translucent clouds, seems to be observable in reasonably dense clouds ...

The Astrophysical Journal, 2023 Precise interstellar dust extinction laws are important to infer the intrinsic properties of reddened objects and correctly interpret observations. In this work, we attempt to measure the optical–infrared extinction laws of the Large and Small Magellanic

The Shape of the Interstellar Reddening Curve [PDF]
International Astronomical Union Colloquium, 1965 When the Observed Spectral Intensity Distribution of an early-type star has been freed from the distortions caused by absorption in the Earth's atmosphere and by instrumental sensitivity factors, it is a measure of the true spectral intensity distribution of the star and of the modifications to that distribution caused by the interstellar material ...

Analysis of Interstellar Extinction towards the Hypergiant Cyg OB2 No. 12
Open Astronomy, 2016 The Cyg OB2 stellar association hosts an entire zoo of unique objects, and among them – an enigmatic star Cyg OB2 No. 12 (Schulte 12, MT 304). MT 304 is enigmatic not only due to its highest luminosity (according to various estimates, it is one of the ...

The Astrophysical Journal, 2023 Dust extinction is one of the fundamental measurements of dust grain sizes, compositions, and shapes. Most of the wavelength-dependent variations seen in Milky Way extinction are strongly correlated with the single parameter R ( V ) = A ( V )/ E ( B − V )

SpeX Near-infrared Spectroscopic Extinction Curves in the Milky Way
The Astrophysical Journal, 2022 Interstellar dust extinction curves provide valuable information about dust properties, including the composition and size of the dust grains, and are essential to correct observations for the effects of interstellar dust.

Luminosity class of the symbiotic stars 4U1954+319 and ZZ CMi [PDF]
Serbian Astronomical JournalWe performed optical photometry and spectral observations of the symbiotic stars 4U1954+319 and ZZ CMi. For 4U1954+319, using high-resolution spectra, we, measure the equivalent widths of diffuse interstellar bands (DIBs) and estimate the interstellar ...
