摘要: Following a summary of early solar EUV spectroscopy the spectra some late-type stars obtained with Extreme Ultraviolet Explorer (EUVE) are briefly surveyed. Some transitions which not included in current emissivity codes but could lead to numerous weak lines, and an apparent continuum EUVE short wavelength region, discussed. The importance geometry adopted when interpreting emission measure distribution is stressed, since radial factors can gradient that steeper than value 3/2 expected plane parallel geometry.
