Grigor Gurzadyan (October 15, 1922 - February 22, 2014) was an Armenian astronomer, and pioneer of space astronomy. In 1960s and early 1970s he directed the UV and X-ray observations of Sun via Rocket Astrophysical Observatories K-2, K-3 and K-4 by means of ballistic rockets R-5; the first launch being on February 15, 1961 from Kapustin Yar military base in Russia. He predicted magnetic fields in planetary nebulae in 1960s, which were actually discovered in 2005 (Jordan, Werner, O'Toole). He authored theoretical papers on flare stars (predicted negative infrared flares), interstellar matter, binary stars. In 1990s he developed the theory of common chromospheres (roundchromes) of close binary stars and of evolution of binary globular clusters. Read more
