Ti line list for the Lick hallow-cathode lamp
We present the wavelength calibration of the Hamilton echelle spectrograph (the Lick observatory). The main problem of the calibration arises from the fact that thorium lines... -
Partition functions of FeI - FeX
The authors calculated atomic partition functions (APF) for iron ions, FeI-FeX, using recent compilations of atomic energy levels. Observed sets of atomic energy levels were... -
Partition functions of NiI-NiX
The authors calculated atomic partition functions (APF) for nickel ions, Ni I - Ni X, using recent compilations of atomic energy levels. Observed sets of atomic energy levels... -
Iron Project. XLIV. Fe VI.
Relativistic atomic structure calculations for electric dipole (E1), electric quadrupole (E2) and magnetic dipole (M1) transition probabilities among the first 80 fine-structure... -
Ly{alpha} dipolar emission
Computer simulation techniques have been used to calculate the Stark broadening profiles of the hydrogen dipolar Lyman-{alpha} transition and of two-photon absorption,... -
O III recombination coefficients
We calculate effective recombination coefficients for the formation of the 5g-4f lines of O III in the intermediate coupling scheme. Photoionization data for the 5g levels... -
HI and HeII fine structure components
Emissivities have been calculated for fine-structure components of selected UV and optical recombination lines of HI and HeII. Results are given for a range of electron... -
IRON Project XXXV. Fe XXIV and Fe XXV
The first large-scale calculations of relativistic radiative transition probabilities from the Iron Project is reported for dipole allowed and intercombination (E1) transitions... -
Vacuum ultraviolet emission band systems of N2
Observed wavenumbers of the emission lines belonging to 10 vacuum ultraviolet band systems of molecular nitrogen are classified into 283 bands, 220 of them reported for the... -
Polarization profiles of H lines
In this paper we provide extensive tables of the coefficients that are needed in the calculation of the second-order moments of the polarization profiles of hydrogen lines. We... -
Stark broadening
Tables of Stark broadening profiles for the N V 6f, g, h-7f, g, h, i line complex at 4945A have been generated. Modern close-coupling techniques are used for the electron... -

Study of fine-structure constants
A statistical analysis of fine splitting of C IV, N V, O VI, Mg II, Al III and Si IV doublet absorption lines in quasar spectra is carried out in order to estimate a possible... -

Atomic line list for 2MASS J05383296-5904280
Over the past few years, the R-Process Alliance (RPA) has successfully carried out a search for stars that are highly enhanced in elements produced via the rapid neutron-capture... -
Solar beryllium abundance revisited
The present-day abundance of beryllium in the solar atmosphere provides clues about mixing mechanisms within stellar interiors. However, abundance determinations based on the... -
HD spectra in H2-He for gas giant studies
The hydrogen deuteride (HD) molecule is an important deuterium tracer in astrophysical studies. The atmospheres of gas giants are dominated by molecular hydrogen, and the... -
Atomic data in Hf, Os, and Au I-IV
It is now well established that a large amount of heavy (trans-iron) elements are produced during neutron star (NS) mergers. These elements can be detected in the spectra of the... -
Line list for convective blueshift analysis
Stellar variability strongly impacts the search for low-mass exoplanets with radial velocity techniques. Two types of planet-free time series can be used to quantify this... -
Laboratory spectroscopy of isobutene
Isobutene ((CH_3_)2_C=CH_2) is one of the four isomers of butene (C_4_H_8_). After the detection of propene (CH_3_CH=CH_2_) toward TMC-1, and also in the warmer environment of...
