Non-LTE abundances of nitrogen in the Sun and reference A-F type stars
L. I. Mashonkina, T. A. Ryabchikova
A new model atom of nitrogen was developed using the energy levels of N I from laboratory measurements and also predicted in atomic structure calculations and the most up-to-date a…
Influence of departures from LTE on determinations of the scandium abundances in A-B type stars
L. Mashonkina
We developed a comprehensive model atom of Sc II-Sc III. Abundances of scandium for a sample of eight unevolved A9-B3 type stars with well-determined atmospheric parameters were de…
High-precision photometric and high-resolution spectroscopic characterisation of HD 180347
Otto Trust, Lyudmila Mashonkina, Edward Jurua +3
We report the analysis of high-precision space-based photometric and high-resolution spectroscopic observations of HD 180347. The high-quality light curves from the Transiting Exop…
BD+30549: young helium-weak silicon star in NGC 1333 star-forming region
I. Potravnov, L. Mashonkina, T. Ryabchikova
We present results of the spectroscopic study of the chemically peculiar star BD+30549 which is bona-fide member of young NGC 1333 star forming region. We found that the st…
Inelastic processes in strontium-hydrogen collisions and their impact on non-LTE calculations
Svetlana A. Yakovleva, Andrey K. Belyaev, Lyudmila I. Mashonkina
Inelastic processes rate coefficients for low-energy Sr + H, Sr + H, Sr + H and Sr + H collisions are calculated using multichannel quantum model approach. 3…
The Pristine survey -- XVII. The C-19 stream is dynamically hot and more extended than previously thought
Zhen Yuan, Nicolas F. Martin, Rodrigo A. Ibata +22
The C-19 stream is the most metal poor stellar system ever discovered, with a mean metallicity . Its low metallicity dispersion ( 0.18 at…
