With the help of amateur astronomers who laid the groundwork, an international team of astronomers has discovered a new type of nebulae around binary stars that they're calling galactic emission nebulae.The binary star YY Hya is at the center of this discovery. YY Hya is a periodic variable star consisting of a K dwarf star and a hot white dwarf partner.
Before that, it went through a red giant phase when it dispersed its outer layers of gas into space. Inside this common envelope, both stars continue to evolve as if they were alone, with the stellar radiation lighting up the dispersed gas.. The lead author is Stefan Kimeswenger from the Department of Astro and Particle Physics at Innsbruck University, Austria.,"Toward the end of their lives, normal stars inflate into red giant stars.
