AtomDB in 2019: New models and features for modeling X-ray emission
Abstract
The AtomDB project provides an database of atomic data and a range of plasma models to allow modeling of a variety of astrophysical phenomena, focusing on the X-ray and EUV wavelengths. With both the currently available high resolution instruments on Chandra and XMM-Newton, and the upcoming microcalorimeter instruments on XRISM and Athena, accuracy and completeness of the database and models are of ever increasing importance. In addition, tools to access and manipulate the database are essential for the data. We present here recent updates to the AtomDB project to enable this. This includes the full release of the AtomDB Charge Exchange model, version 2, based on the Kronos database. This enables rapid modeling of velocity dependent charge exchange cross sections in an X-ray emitting plasma. We also use this as an example for discussing issues raised by converting atomic data into a model which can be readily used by astronomers: sometimes complexity must be reduced to obtain tractable models: what data we can usefully preserve depends on the model. In addition, we present new access and updating tools, allowing access to and modification of the AtomDB database and the models it contains using python 3.
