  • NLTE for APOGEE: simultaneous multi-element NLTE radiative transfer

    Context. Relaxing the assumption of local thermodynamic equilibrium (LTE) in modelling stellar spectra is a necessary step to determine chemical abundances to better than about 10% in late-type stars. Aims: We describe our multi-element (Na, Mg, K, and Ca) non-LTE (NLTE) calculations, which can be applied to the APOGEE survey. Methods: The new

  • Numerical simulations of large-amplitude oscillations in flux rope solar prominences

    Context. Large-amplitude oscillations (LAOs) of solar prominences are a very spectacular, but poorly understood, phenomena. These motions have amplitudes larger than 10 km s-1 and can be triggered by the external perturbations such as Moreton or EIT waves. Aims: Our aim is to analyze the properties of LAOs using realistic prominence models and the
