Statistical Confirmation of the Ultraviolet Spectral Classification System Based on IUE Low-Dispersion Stellar Spectra

Heck, A.; Egret, D.; Nobelis, Ph. +1 more

In theIUE Low-Dispersion Spectra Reference Atlas (Hecket al., 1984a), a new spectral classification system specific to the UV had to be introduced because of the lack of one-to-one correspondence between the UV and visible ranges. It was elaborated from a classical morphological approach (Jaschek and Jaschek, 1984). This paper presents an independ…

Stellar chromospheres, coronae, and winds (invited review)

Simon, T.

Within the last few years there have been important advances in our understanding of the chromospheres, coronae, and winds of late-type stars. This progress has been the result of ultraviolet and X-ray observations obtained from space with theInternational Ultraviolet Explorer andEinstein satellites. In addition, ground-based astronomy has contrib…
