Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Epsilon Boötis is a double star in the constellation Boötes. It has the traditional names Izar and Pulcherrima. Epsilon Boötis consists of a bright orange giant and a smaller main sequence star. The orange giant is a fairly late-stage star well into its stellar evolution, having already exhausted its supply of hydrogen fuel. By the time the smaller main sequence star reaches this point in its evolution, the larger star will have lost much of its mass in a planetary nebula and will have evolved into a white dwarf, and the pair will have essentially changed roles: the brighter star becoming the dim dwarf, while the lesser star will shine as a bright orange giant.
