Spectral line — Continuous spectrum Emission line … Wikipedia
Doppler broadening — In atomic physics, Doppler broadening is the broadening of spectral lines due to the Doppler effect caused by a distribution of velocities of atoms or molecules. Different velocities of the emitting particles result in different (Doppler) shifts … Wikipedia
Doppler effect — Change of wavelength caused by motion of the source. An animation illustrating how the Doppler effect causes a car engine or siren to soun … Wikipedia
Doppler imaging — Not to be confused with Doppler ultrasound. Inhomogeneous structures on stellar surfaces, i.e. temperature differences, chemical composition or magnetic fields, create characteristic distortions in the spectral lines due to the Doppler effect.… … Wikipedia
Spectral linewidth — The spectral linewidth characterizes the width of a spectral line, such as in the electromagnetic emission spectrum of an atom, or the frequency spectrum of an acoustic or electronic system. For example, the emission of an atom usually has a very … Wikipedia
Hydrogen line — For hydrogen lines in general, see Hydrogen spectral series. The hydrogen line, 21 centimeter line or HI line refers to the electromagnetic radiation spectral line that is created by a change in the energy state of neutral hydrogen atoms. This… … Wikipedia
Gaussian broadening — refers to broadening effects in spectral lines, these can be produced by Doppler broadening and natural broadening.This effect is similar to Gaussian blur effect in image processing produced by convolution with the Gaussian function.The term is… … Wikipedia
List of probability distributions — Many probability distributions are so important in theory or applications that they have been given specific names.Discrete distributionsWith finite support* The Bernoulli distribution, which takes value 1 with probability p and value 0 with… … Wikipedia
