Line Formation

open access: yesПроект Байкал, 2022
The article is devoted to the features and origins of Nikolay Milyutin’s urban planning theory. Written long before the completion of his formal education, his book “Socialist city” became extremely popular among the planners and architects of the 20th ...

Chromospheric Dynamics and Line Formation [PDF]

open access: yesAIP Conference Proceedings, 2007
The solar chromosphere is very dynamic, due to the presence of large amplitude hydrodynamic waves. Their propagation is affected by NLTE radiative transport in strong spectral lines, which can in turn be used to diagnose the dynamics of the chromosphere.

Taming contact line instability for pattern formation

open access: yesNature Communications, 2016
Coating flows on surfaces are very useful in many industrial applications such as printing organic electronics, but it is challenging to control the process owing to unstable flow. Here, Deblais et al.

Stark Broadening of Al IV Spectral Lines

open access: yesUniverse, 2023
Stark widths for 23 transitions in Al IV have been calculated by employing the modified semiempirical method. The results are obtained for an electron density of 1017 cm−3 and temperatures from 10,000 K to 160,000 K.

Stark Width Data for Tb II, Tb III and Tb IV Spectral Lines

open access: yesData, 2021
A dataset of Stark widths for Tb II, Tb III and Tb IV is presented. To data obtained before, the results of new calculations for 62 Tb III lines from 5d to 6pj(6,j)o, a transition array, have been added.

The XSTAR Atomic Database

open access: yesAtoms, 2021
We describe the atomic database of the xstar spectral modeling code, summarizing the systematic upgrades carried out in the past twenty years to enable the modeling of K-lines from chemical elements with atomic number Z≤30 and recent extensions to handle

The disk emission in single peaked lines for 12 AGNs [PDF]

open access: yesSerbian Astronomical Journal, 2008
The disk emission in the single peaked Broad Emission Lines (BELs) of Active Galactic Nuclei (AGNs) is difficult to detect. In order to find the disk traces in BELs the line profiles were simulated by the simplified model consisting of two components ...

NLTE Analysis of High-Resolution H-Band Spectra, V: Neutral Sodium

open access: yesUniverse, 2023
In order to derive sodium abundances and investigate the effects of non-local thermodynamic equilibrium (NLTE) on the formation of H-band Na I lines, we update the sodium atomic model by incorporating collision rates with hydrogen from new quantum ...
