JENAM-2007 In Armenia

 

The Joint European and National Astronomy Meeting (JENAM) in 2007 took place on August 20-25 in Yerevan, Armenia. It was the 15th annual meeting of the European Astronomical Society (EAS) and the 6th annual meeting of the Armenian Astronomical Society (ArAS). JENAM-2007 consisted of 6 Plenary sessions, 8 EAS symposia and 5 special sessions. In addition, the EAS General Meeting was held on August 22, and the EAS Council Meeting was held on August 21. JENAM-2007 was organized by EAS, ArAS, the Yerevan State University (YSU, the venue of JENAM), and the Byurakan Astrophysical Observatory (BAO). The international Scientific Organizing Committee (SOC) had 16 members from 10 countries, including the EAS and ArAS leaders and most of the chairmen of the EAS symposia and JENAM special sessions:

ANNIVERSARIES

 

Grigor GURZADYAN 85

 

Grigor Gurzadyan was born on October 15, 1922 in Baghdad. Upon graduating the Yerevan Polytechnic Institute in 1944, he became the postgraduate of Victor Ambartsumian, who had just moved to Armenia. He defended his Ph.D. in 1948 and became doctor of Science in 1955. Being in Ambartsumian's founding team of Byurakan observatory, he later headed a Laboratory, in 1960s became deputy director of the observatory for space research. He headed the branch of Byurakan observatory on space research, Garni space astronomy laboratory (later Institute, 1992-2004). He is among the pioneers of space astronomy. In 1960s he directed the UV and X-ray observations of sun and stars using ballistic rockets R-5, the first launch being on February 15, 1961 from Kapustin-Yar base. Spectra of thousands of stars to as faint as 13th magnitude were obtained. In April, 1971, the first space station Salyut 1 carried into orbit Orion 1, the first space telescope with an objective prism.

 

Gurzadian authored theoretical papers on planetary nebulae, interstellar matter, and flare stars. In 1990s he developed the theory of common chromospheres (roundchromes) of close binary stars and of evolution of binary globular clusters.

 

For decades he lectured in Yerevan State University (theoretical astrophysics) and in Polytechnic Institute (precise mechanics). He has published over 200 papers and a number of monographs, including "Radioastrophysics", "Planetary Nebulae", "Flare Stars", "Stellar Chromospheres", "Physics and Dynamics of Planetary Nebulae", "Theory of Interplanetary Flights", "Space Dynamics".

 

Gurzadian is a member of the Armenian Academy of Sciences (1986, corresponding member from 1965).

 

Agop TERZAN - 80

 

Famous Armenian astronomer Agop Terzan was born on October 31 1927 in Istanbul. He got his Bachelor degree on Mathematical and Astronomical Science in 1945 and Masters on Astronomy in 1949. He defended his PhD degree in 1965 at Lyon University. During 60s he discovered 710 variable stars in the immediate vicinity of 14 globular clusters. Later he discovered 11 new globular clusters, 158 diffuse nebulae, 124 galaxies, from which 25% appeared to be active galaxies of Sy2 type. In direction to the Galactic center Terzan discovered 4430 new variable stars, including 458 ones identified later with the IRAS sources. Another large work was the discovery of 1428 high proper motion stars (m > 0".1 per year).

 

Terzan is a member of French National Astronomy Committee, International Astronomical Union (IAU) and a number of other international organizations. Among his numerous awards and honors are Henry Rey price of the French Astronomical Society and a number of medals. Agop Terzan has visited Armenia many times including his official missions to Byurakan in 1971, 1973, 1977, 1984, and 1989. He has published more than 100 papers on the above mentioned subjects.

 

Vagharshak SANAMIAN - 90

 

Vagharshak Sanamian was born in 1917 in Karabagh. After finishing the local school he moved to Yerevan, where he applied for the Yerevan State University, Department of Engineering-Mathematics. Soon, after the application, the First World War began and he was called to serve in the Soviet army. During his service he managed to get theoretical courses at radio-locational department at the Military Electrical-Technical Academy after S.M. Budyony in Leningrad. In 1946 he returned from the army and graduated from the Yerevan State University Department of Engineering-Mathematics. He had worked from 1949 to 1950 at the Yerevan State University at the Mathematical Department. Starting from 1950 he was at Byurakan Observatory as a senior researcher. In 1957 he defended PhD thesis on radio astronomy and his supervisor was famous Russian radio astronomer S.E.Khaikin. For number of years he supervised radio astronomical studies in Byurakan Astrophysical Observatory. He participated in a number of international collaborations including collaboration between BAO and Indian Astronomical Centers. He worked on flare stars, Sun and Markarian galaxies, Herbig-Haro Objects and other important radio sources. He also worked for a number of years Institute of Radiophysics and Electronics in Ashtarak. He is an ArAS member from 2005.

 

Arthur AMIRKHANIAN - 60

 

Artur Amirkhanian was born on July 20 1947 in Port-Artur. He started working at Byurakan Astrophysical Observatory from 1975. He was the head of the laboratory of 2.6 m telescope. He defended his PhD degree 1989, under E.Ye.Khachikian supervision. His main research area includes groups and clusters of galaxies in particular Shahbazian compact groups of compact galaxies. He published about 26 scientific papers.

 

Ashot HAKOPIAN - 50

 

Ashot Hakopian was born on 11 August 1957 in Yerevan. In 1979 he has graduated from the Yerevan State University department of physics and the same year he started working at Byurakan Astrophysical Observatory. Since 2000 he lectures at the Yerevan State University different courses. He has published a number of scientific papers. His main research area includes statistical studies of variable stars.

CALL FOR ARAS ANNUAL PRIZE FOR YOUNG ASTRONOMERS

 

ArAS fourth Annual Prize for Young Scientists will be awarded at the end of this year. As in previous years, the prize will be awarded to a young scientist under 35 working in astronomy or related field and showing significant results in research and/or other scientific activities connected anyhow with the Armenian astronomy. Nominations may be made by members or any research organization from Armenia or elsewhere and should be sent to one of the ArAS Co-Presidents. They should include personal data for the nominee and a brief description of his/her achievements during the year, including important scientific results, all published papers, participation in meetings, given talks, etc., whatever is considered to be important. The deadline for applications is December 1. The selection will be made by a special committee and the results will be announced in the last issue of ArAS Newsletter at the end of each year. A diploma and sum of $100 will be awarded to the winner. As in the previous years, the ArAS Co-President Prof. Yervant Terzian is sponsoring the annual Prize for Young Scientists in 2007, too.
