Line profiles in expanding atmospheres [PDF]

open access: yesSymposium - International Astronomical Union, 1994
The analysis of the UV resonance transitions of superionized species observed in early-type stars suggests the presence of a high temperature region and an outward flow of matter (Snow & Marlborough 1976).

Stark Broadening of Several Ne II, Ne III and O III Spectral Lines for the Stark-B Database

open access: yesOpen Astronomy, 2011
In order to complete Stark broadening data for Ne II and O III lines, needed for analysis of stellar atmospheres, we determined the missing parameters for the broadening by collisions with protons and ionized helium for 15 Ne II and 5 O III multiplets ...

An Engineered CRISPR-Cas9 Mouse Line for Simultaneous Readout of Lineage Histories and Gene Expression Profiles in Single Cells

open access: yesbioRxiv, 2019
Tracing the lineage history of cells is key to answering diverse and fundamental questions in biology. Particularly in the context of stem cell biology, analysis of single cell lineages in their native state has elucidated novel fates and highlighted ...

Forty Years of the Applications of Stark Broadening Data Determined with the Modified Semiempirical Method

open access: yesData, 2020
The aim of this paper is to analyze the various uses of Stark broadening data for non-hydrogenic lines emitted from plasma, obtained with the modified semiempirical method formulated 40 years ago (1980), which are continuously implemented in the STARK-B ...

LINE PROFILES OF CORES WITHIN CLUSTERS. II. SIGNATURES OF DYNAMICAL COLLAPSE DURING HIGH-MASS STAR FORMATION [PDF]

open access: yes, 2013
Observations of atomic or molecular lines can provide important information about the physical state of star-forming regions. In order to investigate the line profiles from dynamical collapsing massive star-forming regions (MSFRs), we model the emission ...

Data on Stark Broadening of N VI Spectral Lines

open access: yesData
Data on Stark broadening parameters, spectral line widths, and shifts for 15 multiplets of N VI, whose spectral lines are broadened by collisions with electrons, protons, alpha particles (He III) and B III, B IV, B V and B VI ions, are presented.

Stark Broadening of Cr III Spectral Lines: DO White Dwarfs

open access: yesAtoms, 2018
Using the modified semiempirical method of Dimitrijević and Konjević, Stark widths have been calculated for six Cr III transitions, for an electron density of 10 17 cm ‒ 3 and for temperatures from 5000–80,000 K.

Stark Broadening of Co II Lines in Stellar Atmospheres

open access: yesData, 2020
Data for Stark full widths at half maximum for 46 Co II multiplets were calculated using a modified semiempirical method. In order to show the applicability and usefulness of this set of data for research into white dwarf and A type star atmospheres, the

Hydrogen Line Profiles [PDF]

open access: yesHighlights of Astronomy, 1995
Observed hydrogen line profiles are an enormously important source of diagnostic information about virtually all kinds of astronomical bodies. Therefore, it is important to understand the hydrogen line formation in sufficient detail to be able to achieve a high degree of reliability by analyzing observed hydrogen line profiles.Calculation of the ...
