WebDec 1, 1983 · The Kg line emission is the strongest emission of a prominence and as it has a large optical depth, it probably contains important information on prominence physics. However, because self-reversal is usually the case, the analysis of the Hg, profile has been a difficult problem. A hydrogen atom consists of an electron orbiting its nucleus. The electromagnetic force between the electron and the nuclear proton leads to a set of quantum states for the electron, each with its own energy. These states were visualized by the Bohr model of the hydrogen atom as being distinct orbits around the nucleus. Each energy level, or electron shell, or orbit, is designated … medication for pots disease https://lanastiendaonline.com

WebApr 22, 2024 · By definition, classical Be stars are hot, non-supergiant, non-radially pulsating, rapidly rotating B-type stars, which show or have shown one or more Balmer lines in emission (most prominently in H α) [24,25,26]. Their rotation speeds are presumed to be near their critical velocity and they have strong stellar winds and a high mass-loss rate.

WebThis “Balmer line crisis” was noted in several earlier works and is now confirmed and constrained by RM measure-ments that were not available in the past.
