To provide a complete understanding of these phenomena a wide variety of studies is presented in this volume. The contributions are broadly divided between line and continuum variability, with observational results, methodological approaches, and theoretical models accompanying each. The final part is devoted to the important aspect of propagation-induced variability. 410 0$aLecture Notes in Physics,$x0075-8450 ;$v377 606 $aObservations, Astronomical 606 $aAstronomy?Observations 606 $aAstrophysics 606 $aGeophysics 606 $aAstronomy, Observations and Techniques$3https://scigraph.springernature.com/ontologies/product-market-codes/P22014 606 $aAstrophysics and Astroparticles$3https://scigraph.springernature.com/ontologies/product-market-codes/P22022 606 $aGeophysics/Geodesy$3https://scigraph.springernature.com/ontologies/product-market-codes/G18009 615 0$aObservations, Astronomical. 615 0$aAstronomy?Observations. 615 0$aAstrophysics. 615 0$aGeophysics. 615 14$aAstronomy, Observations and Techniques. 615 24$aAstrophysics and Astroparticles. 615 24$aGeophysics/Geodesy. 676 $a523.1/12 702 $aDuschl$b W.
