Version 11 of the chianti database and software package is presented. Advanced ionization equilibrium models have been added for low charge states of seven elements (C, N, O, Ne, Mg, Si, and S), and represent a significant improvement especially when

Coronal mass ejections (CMEs) expel multithermal, magnetized plasma from the Sun, and when directed toward Earth, can cause extensive damage to space and ground-based electronics. To better understand the triggering, acceleration, and evolution of CM

We report the first time-dependent spectral atlas of a coronal mass ejection (CME) observed by the Hinode/Extreme Ultraviolet Imaging Spectrometer (EIS). EIS observed the Cartwheel CME on 2008 April 9 at 09:30–10:00 UT in its full wavelength range

This paper outlines the necessity for the availability, accessibility, and expansion of atomic physics data and analysis tools for the meaningful interpretation of spectroscopic and polarimetric observations. As we move towards observing the Sun at h

In this work, we combined AWSoM’s nonequilibrium ionization (NEI) calculations from Szente et al. with the synthetic spectral computations of SPECTRUM to predict nonequilibrium line intensities across the entire domain of the AWSoM 3D global model.

The CHIANTI atomic database provides sets of assessed data that are used for simulating spectral observations of astrophysical plasmas. This article describes updates that will be released as version 10.1 of the database. A key component of CHIANTI i

Geopolymer-hydrotalcites composites have been prepared and compared to explore their use in the field of CO2 adsorption for a wide range of working temperatures and relative applications. Two commercial hydrotalcites, with different Mg:Al ratio, were

We realized a laboratory experiment to study the scattering polarization of the Na I D-doublet at 589.0 and 589.6 nm in the presence of a magnetic field. This work was stimulated by solar observations of that doublet, which have proven particularly c
