| Abstract: |
The technique of Doppler tomography is now an important tool for astronomers investigating the spectra of close binary stars. The method has proven invaluable in the study of emission lines from accretion disks in cataclysmic variables, and it also plays a central role in the reconstruction (or disentangling) of the component spectra in double-lined spectroscopic binary stars. Here I focus on the latter application and discuss how Doppler tomography can help us study the stellar parameters of individual stars in close binaries. I review some of the results from tomography on unevolved and evolved binaries plus binaries in multiple star systems. I also discuss the application of tomography to the reconstruction of maps of circumstellar emission regions in massive binaries. |
