BRASS Release 2021

BRASS Rationale

The Belgian Repository of Atomic data and Stellar Spectra - BRASS is a Science Research Networking Project of the Belgian Federal Science Policy Office - BRAIN.be. The project is a large scientific collaboration on astrophysics research of the Royal Observatory of Belgium (ROB), University of Leuven (KUL), European Southern Observatory (ESO) at Paranal, Chile, and Université Libre de Bruxelles (ULB), University of Antwerp (UA), and the Vereniging voor Sterrenkunde (VVS).

BRASS takes a crucial step towards removing all systematic errors in atomic input data required for quantitative stellar spectroscopy. The project thoroughly assesses the quality of fundamental atomic data available in the largest repositories by comparing very high-quality observed stellar spectra with state-of-the-art theoretical spectra.

More information about the context, major research questions, methodology, interdisciplinary, and research results of the BRASS project is provided here.
