Context. Mass loss of ∼ 0.1-0.3 M⊙ from Population II red giant stars (RGB) is a requirement of stellar evolution theory in order to account for several observational evidences in globular clust...
Asymmetric Line Profiles in Spectra of Gaseous Metal Disks Around Single White Dwarfs
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
Around several single DAZ and DBZ white dwarfs metal-rich disks have been observed, which are mostly believed to originate from disruption of smaller rocky planetesimals. In some cases the material do...
Iron line profiles in Suzaku spectra of bare Seyfert galaxies
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
We methodically model the broad-band Suzaku spectra of a small sample of six 'bare' Seyfert galaxies: Ark 120, Fairall 9, MCG-02-14-009, Mrk 335, NGC 7469 and SWIFT J2127.4+5654. The analysis of bare ...

THE INFLUENCE OF HYPERFINE STRUCTURE ON SOME MANGANESE LINE PROFILES IN THE SOLAR SPECTRUM
Sun photosphere–Line profiles–techniques spectroscopic
2009/3/11
Taking into account effects of hyperfine structure, we calculated
the synthetic solar spectrum for wavelength intervals around nine neutral manganese
lines. To estimate values of hyperfine component...
