Evolution of debris disks
MC Wyatt - Annu. Rev. Astron. Astrophys., 2008 - annualreviews.org
Circumstellar dust exists around several hundred main sequence stars. For the youngest
stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be …

X-ray spectroscopy of stars
M Güdel, Y Nazé - The Astronomy and Astrophysics Review, 2009 - Springer
Non-degenerate stars of essentially all spectral classes are soft X-ray sources. Their X-ray
spectra have been important in constraining physical processes that heat plasma in stellar …
