Prof. Melikian was born on December 27, 1948 in Artashat (Armenia). After gradu- ating from the Faculty of Physics of the Yerevan State University (Armenia) in 1974, he began to work at BAO as an assistant astronomer on flare stars study both in the clusters and in the general stellar field. After obtaining his Ph.D. degree in 1984, the field of his scientific interests became much wider including new types of variable or non-stationary stellar objects such as T Tau stars, cataclysmic variables, Herbig-Haro objects, Mira vari- ables, etc, especially those belonging to the binary systems. He has published around 150 scientific papers in AJ, ApJ, A&A, PASP, Astrophysics, etc. as well as participated with valuable contributions in a large number of scientific Symposia and Meetings worldwide. Prof. Melikian was a member of the International Astronomical Union (1994), the Euro- pean Astronomical Society (1992), and founding member of the Armenian Astronomical Society (2001). In 2006 he was appointed the Deputy Director of the BAO and was a member of the BAO Scientific Council since 1994. In recent years, he was actively en- gaged in a scientific collaboration project with the Astronomical Observatory R. M. Aller of the University of Santiago de Compostela (OARMA), where the speckle-interferometry camera of OARMA was moved to in 2011 under agreement between OARMA and BAO. The camera was attached to the 2.6m telescope of BAO for speckle astrometric observa- tions of binaries as well as for photometric and spectroscopic observations with the same telescope. Several OARMA young researchers have completed their scientific research with long-term stays and observational runs in BAO. 8 Norik will be much missed by all who knew him. He is survived by his wife Marine, son Davit and daughter Astgik. Rest in peace. V. S. Tamazian J. A.
