PHANGS-ML: The Universal Relation between PAH Band and Optical Line Ratios across Nearby Star-forming Galaxies

The Astrophysical Journal
The structure and chemistry of the dusty interstellar medium (ISM) are shaped by complex processes that depend on the local radiation field, gas composition, and dust grain properties. Of particular importance are polycyclic aromatic hydrocarbons (PAHs),

Diffuse interstellar bands in the spectra of Herbig Ae/Be stars and related objects

, 2003
We report a detection of weak diffuse interstellar bands (DIBs) in the close vicinity of 6 Herbig Ae/Be pre-main sequence stars. A common feature of these objects is the presence of a dusty shell where DIB carriers are apparently formed/destroyed.

WISE J005128.08+645651.7: An enigmatic R Coronae Borealis star

Astronomy & Astrophysics
Context. R Coronae Borealis (RCB) stars are hydrogen-deficient and carbon-rich (HdC) supergiants that likely originate from a merger of two white dwarfs.

Diffuse Interstellar Bands and Their Families

, 2006
Diffuse interstellar bands (DIBs) still await an explanation. One expects that some progress in this field will be possible when all the known DIBs are divided into families in such a way that only one carrier is responsible for all bands belonging to the given family.

Interstellar Lines and Diffuse Bands in the Spectrum of the Supergiant κ Cas

, 2019
© 2019, Pleiades Publishing, Ltd. We have studied the interstellar lines and diffuse bands in the spectrum of the supergiant κ Cas using the CCD spectra obtained with the Echelle spectrograph of the 2 meter telescope at the peak Terskol observatory.
