Contribution
It provides a comprehensive review of spectral disentangling methods and recent applications to different types of binary stars, highlighting new insights into their chemical evolution.
Findings
Spectral disentangling allows chemical analysis of binary star components.
Applications include high-mass, intermediate-mass, and mass-transfer binaries.
The method enhances understanding of stellar evolution in binary systems.
Abstract
The method of spectral disentangling has now created the opportunity for studying the chemical composition in previously inaccessible components of binary and multiple stars. This in turn makes it possible to trace their chemical evolution, a vital aspect in understanding the evolution of stellar systems. We review different ways to reconstruct individual spectra from eclipsing and non-eclipsing systems, and then concentrate on some recent applications to detached binaries with high-mass and intermediate-mass stars, and Algol-type mass-transfer systems.
