Young exoplanets trace planetary evolution, in particular the atmospheric mass loss that is most dynamic in youth. However, the high activity level of young stars can mask or...

We have previously presented evidence for a varying fine-structure constant, {alpha}, in two independent samples of Keck/HIRES quasi-stellar object (QSO) absorption spectra....

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...

New tables of Stark broadened hydrogen Lyman, Balmer and Paschen lines are presented for a wide range of plasma conditions, allowing the complete spectrum of these series to be...

This catalogue is an extension in the ultraviolet region (129 to 3903 Angstroems) of the ILLSS catalogue (Coluzzi, 1993; catalog ) which lists lines in the optical region. The...

This catalogue is a revised version of the Identification List of Lines in Stellar Spectra and now lists wavelength, spectrum, multiplet number, intensity, ionisation potential...

This compilation is aimed at providing a general catalog of atomic lines for comparatively low-ionized species, laying emphasis on their transition probabilities. Please refer...

Line emissivities, effective recombination coefficients, opacity factors, departure coefficients and total recombination coefficients are calculated for hydrogenic ions with...

The machine-readable version of "A Multiplet Table for MnI" contains data on excitation potentials, J values, multiplet terms, intensities of the transitions, and multiplet...

The primary references for stellar line identifications in the optical and ultraviolet spectral regions have been "A Multiplet Table of Astrophysical Interest" (RMT, Moore 1945)...

This catalog contains wavelength information for 99 different atomic species. The wavelengths for about 46,610 spectral lines of neutral through quadruply ionized atoms are...

This is the final report of a three-paper series on the K-shell photoabsorption and photoionization of trace elements (low cosmic abundance), namely F, Na, P, Cl, K, Sc, Ti, V,...

We present the results of a calculation of recombination coefficientscients for O^2 + ^+e^-^ using an intermediate coupling treatment that fully accounts for the dependence of...

The list presents electron collision strengths for the forbidden transitions between the fifteen lowest levels of the doubly-ionized cobalt, Co^2+^, as a function of the...

The list presents electron collision strengths for the forbidden transitions between the fifteen lowest levels of the singly-ionized cobalt, Co^+^, as a function of the electron...

The list consists of effective collision strengths in the electron excitation (Upsilon) and de-excitation (Downsilon) with a kappa electron energy distribution as a function of...

We present electron collision strengths and their thermally averaged values for the nebular forbidden lines of the astronomically abundant doubly ionized oxygen ion, O^2+^, in...

A computed list of transition lines for the atomic ion C^+^ is generated using R-matrix [1], Autostructure [2] and Emissivity [3] codes. These lines are produced by dielectronic...

We present 'BYTe' a comprehensive 'hot' line list of ro-vibrational transitions of ammonia, ^14^NH_3_, in its ground electronic state. It comprises 1,138,323,351 transitions...

A linelist of vibration-rotation transitions for ^13^C substituted HCN is presented. The line list is constructed using known experimental levels where available, calculated...
