Many types of stars show conspicuous emission lines in their optical spectra. These stars are broadly referred to as emission line stars. Emission line stars are attractive to many people because of their spectacular phenomena and their amazing varieties and variability. This book offers general information on emission line stars, starting from a brief introduction to stellar astrophysics, and then moving to a broad overview of emission line stars including early and late type stars as well as pre-main sequence stars. Detailed references and index are prepared for further reading.

Offers general information on all types of emission line stars for students and researchers who are interested in the active state of stars Emission line stars are closely related to variable stars and together yield the observational basis for an understanding of the evolutionary processes of stars in their active phases Emission line stars are intrinsically attractive due to their amazing variety and variability. They are sometimes even mysterious
