Stellar chromospheres: proceedings of the International Astronomical Union Colloquium held at NASA Goddard Space Flight Center, February , [Stuart D Jordan; Eugene H Avrett; International Astronomical Union. Colloquium; Goddard Space Flight Center.]. Volume 1: The global properties of stars and the observational techniques used to determine them are examined in an introduction for undergraduate students. Chapters are devoted to stellar positions, proper motions, brightness, color-magnitude diagrams, luminosities, angular radii, and effective temperatures. Also considered are stellar masses and radii, spectral classification, population II Cited by: 1. Observations indicating the presence of stellar chromospheres, that is hot envelopes around stars are summarized. Undisputed indicators (called type I) for hot stellar envelopes are spectral lines of highly ionized atoms, Fe ii emission lines and flares in late type stars and the presence of the He i Å line. Whether indicators (called type II) like emission cores in the Ca ii H and K and.

Stellar Chromospheres. Stellar chromospheres and transition regions contain the moderate temperature (5,, K) gas located between the photosphere and corona. These regions are best studied using the emission lines they emit in the ultraviolet. The present conference on cool stars, stellar systems, and the sun encompasses stellar chromospheres and coronae, binary stars, the stellar evolution of contracting stars and red giants, stellar evolution abundances of the elements, mass loss and envelopes, and stellar pulsation. Specific issues addressed include theories regarding the acoustic.

Chromospheres, coronae, and winds similar to those observed on the Sun have been detected in a variety of cool stars. In many cases, especially for main-sequence stars, there is good evidence that the processes leading to non-radiative plasma heating and wind acceleration are the same as for the Sun, although the radiative losses from stellar chromospheres and coronae are often some Cited by: 4.
