Available  throughout the radio spectrum, these lines carry information  regarding the density, temperature, turbulence and velocity of  thermal plasmas. Their very existance shows the presence of thermal  gas. They also can carry information regarding magnetic fields if  Zeeman splitting were to be detected. \u003cbr\u003e  Containing the proceedings of an IAU Colloquium celebrating the 25th  anniversary of their detection, this volume tells us what has  happened since. It contains the story of the detection of RRLs and  reviews of many areas of physics of the interstellargas from which  stars form, HII regions excited by newly formed stars, planetary  nebulae involving dying stars, and the structure of our Milky Way and  other galaxies reflecting the large-scale morphology of the star  formation process. In addition there is an article describing modern  laboratory studies of Rydberg atoms to probe the basic physics of  atomic structure, and articles describing the theory of collisions  and radiation upon Rydberg atoms leading to observate effects to be  used as diagnostic tools in astromony. \u003cbr\u003e  This book focuses on the 25 years of astronomical research with radio  recombination lines (RRLs) since their discovery in 1965. It covers a  wide range of topics: papers dealing with research into Rydberg atoms  both in the laboratory and in the interstellar medium of our galaxy  and others; papers on the interaction of radiation and atomic  systems, as well as with the effects of inadiabatic collisions  between these atoms and both ions and electrons. It deals with  astronomical observations of atoms with `diameters' ranging from 0.08  to 50 mum a size factor of 625. It deals with RRLs in  absorption,  in emission and as true masers. And it deals with plasmas  with  temperatures ranging from 10 to greater than 10\u003csup\u003e4\u003c\/sup\u003e  kelvins, andwith an even greater range of volume densities. \u003cbr\u003e  Much new work is reported, including low frequency RRLs discovered in  1980 and the maser RRLs from the star MWC349, discovered in 1989. The  advent of aperture synthesis telescopes and large single-element  telescopes have made possible RRL studies with high angular  resolution. The sum total of the work reported here will make the  volume a platform from which to search new horizons in RRL research.  \u003cbr\u003e\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2011-09-28\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9789401067683\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-94-009-0625-9\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 312\u003c\/p\u003e ","brand":"Springer Netherlands","offers":[{"title":"Default Title","offer_id":47661322141836,"sku":"9789401067683","price":49.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9789401067683.jpg?v=1776428343","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9789401067683","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
