Chromospheres

WebThe temperature of the chromosphere is several times higher than that of the photosphere. The outermost portion of the sun is called the corona and is composed of extremely rarefied gases called the solar winds, which are thought to extend into the solar system. WebHigh-resolution Ca II K line profiles are used to model the upper photospheres and lower chromospheres of eight main-sequence stars ranging in spectral type from F0 to M0 and exhibiting different degrees of chromospheric activity. The model chromospheres are studied as a function of spectral type and activity for stars of similar spectral type in order …
