(De)excitation rates of H2O by H2
The interpretation of water line emission from existing observations and future HIFI/Herschel data requires a detailed knowledge of collisional rate coefficients. Among all... -
Code for automatic determination of EW (ARES)
We present a new automatic code (ARES) for determining equivalent widths of the absorption lines present in stellar spectra. We also describe its use for determining fundamental... -
IRON project LXIV
This work reports radiative transition rates and electron impact excitation rate coefficients for levels of the n=3, 4, 5, 6, 7, 8 configurations of CaII. The radiative data... -
Thorium and argon lines in the visible
We present a new list of thorium and argon emission lines in the visible obtained by analyzing high-resolution (R=110000) spectra of a ThAr hollow cathode lamp. The aim of this... -
Ionization rate coefficients for elements H to Zn
The interpretation of astrophysical spectra depends directly on a knowledge of the ionization state of the emitting plasma. This is determined, in part, from collisional... -
