Extensive study of HD 25558, a long-period double-lined binary with two SPB components
Á. Sódor, P. De Cat, D. J. Wright +33
We carried out an extensive observational study of the Slowly Pulsating B (SPB) star, HD 25558. The ~2000 spectra obtained at different observatories, the ground-based and MOST sat…
Ion-atom radiative processes in the solar atmosphere: quiet Sun and sunspots
V. A. Sreckovic, A. A. Mihajlov, Lj. M. Ignjatovic +1
In the previous works the significance of the symmetric and non-symmetric ion-atom absorption processes in far UV and EUV regions within a model of the quiet Sun atmosphere, has be…
The STARK-B database as a resource for \textquotedblleft STARK" widths and shifts data: State of advancement and program of development
Sylvie Sahal-Bréchot, Milan S. Dimitrijević, Nicolas Moreau +1
\textquotedblleft Stark" broadening theories and calculations have been extensively developed for about 50 years and can now be applied to many needs, especially for accurate spect…
The OIV 1407.3Å/1401.1Å emission-line ratio in a plasma
Nabil Ben Nessib, Norah Alonizan, Rabia Qindeel +2
Line ratio of O IV 1407.3 Å/1401.1 Å\- is calculated using mostly our own atomic and collisional data. Energy levels and oscillator strengths needed for this calculation have been…
Stark broadening data for spectral lines of rare-earth elements: Nb III
Zoran Simić, Milan S. Dimitrijević, Luka Č. Popović
The electron-impact widths for 15 doubly charged Nb ion lines have been theoretically determined by using the modified semiempirical method. Using the obtained results, we consider…
Stark widths of Ar III spectral lines in the atmospheres of subdwarf B stars
Rafik Hamdi, Nabil Ben Nessib, Sylvie Sahal-Bréchot +1
Using semiclassical perturbation approach in impact approximation, we have calculated Stark widths for 32 spectral lines of doubly charged argon (Ar III). Oscillator strengths are…
Stark broadening of B IV lines for astrophysical and laboratory plasma research
Milan S. Dimitrijević, Magdalena Christova, Zoran Simić +2
Stark broadening parameters for 36 multiplets of B IV have been calculated using the semi-classical perturbation formalism. Obtained results have been used to investigate the regul…
Boundary conditions for NLTE polarized radiative transfer with incident radiation
Marianne Faurobert, Ivan Milic, Olga Atanackovic
Polarized NLTE radiative transfer in the presence of scattering in spectral lines and/or in continua may be cast in a so-called reduced form for six reduced components of the radia…
Is There a Third Component in the Intermediate Polar V405 Aur?
Vitalii V. Breus, Ivan L. Andronov, Pavol Dubovsky +10
Variability of the spin period of the white dwarf in the V405 Aur (RX J0558.0+5353) system using our observations and previously published maxima timings is analyzed. As the phase…
Variability of the Spin Period of the White Dwarf in the Intermediate Polar V405 Aur: Low-Mass Third Body or Precession ?
V. V. Breus, I. L. Andronov, P. Dubovsky +9
We present the results of photometric CCD observations of the magnetic cataclysmic variable V405 Aurigae (RX J0558.0+5353 = 1RXS J055800.7+535358) obtained using different instrume…
On the accretion disc and evolutionary stage of beta Lyrae
R. E. Mennickent, G. Djurašević
We modeled the V-band light curve of beta Lyrae with two stellar components plus an optically thick accretion disc around the gainer assuming a semidetached configuration. We prese…
Fundamental stellar and accretion disc parameters of the eclipsing binary DQ Velorum
D. Barría, R. E. Mennickent, L. Schmidtobreick +5
To add to the growing collection of well-studied double periodic variables (DPVs) we have carried out the first spectroscopic and photometric analysis of the eclipsing binary DQ Ve…
Excitation and deexcitation processes in atom-Rydberg atom collisions in helium-rich white dwarf atmospheres
V. A. Sreckovic, A. A. Mihajlov, Lj. M. Ignjatovic +1
We aim to show the importance of non-elastic excitation and deexcitation processes in collisions with the principal quantum number $n \ge…
