Evolution of Cosmic Objects through their Physical Activity

International Conference devoted to V.A. Ambartsumian’s 100th anniversary


September 15-18, 2008, Byurakan, Armenia



The meeting was devoted to the 100th anniversary of the greatest Armenian scientist Viktor Ambartsumian (1908-1996), whose fundamental discoveries changed our views on the evolution of cosmic objects. This was one (the major) of the events dedicated to the centenary. Another conference “Physics of Compact Objects” in Yerevan, the Second Byurakan International Summer School, and some other events were organized as well. The ArAS VII Annual Meeting was also associated with this conference.


Scientific Organizing Committee (SOC): Halton Arp (Germany), Yuri Balega (Russia), Geoffrey Burbidge (USA, Co-chair), Anatoly Cherepashchuk (Russia), Michael Dopita (Australia), Daniel Kunth (France), Hayk Harutyunyan (Armenia, Co-chair), Jayant Narlikar (India), Sadanori Okamura (Japan), Elma Parsamian (Armenia), Roberto Terlevich (Mexico), Ian Robson (UK), David Sedrakian (Armenia), Yervant Terzian (USA).


Local Organizing Committee (LOC): Haik Harutyunian and Areg Mickaelian (Co-Chairs), Elena Nikoghosyan (Secretary).


As this was a general meeting, all subjects related to V.A. Ambartsumian’s scientific achievements were present, including the physics of compact cosmic objects (neutron stars).


Scientific Topics:


·         Stars and Nebulae

·         Pulsars / Neutron Stars

·         Activity in Galaxies

·         Cosmology

·         Light Scattering and Radiative Transfer

·         Miscellanea


The official opening of the meeting took place on September 15 at the presidium of the Armenian National Academy of Sciences (NAS) by the Introductory talk by the President of the Armenian NAS Prof. Radik Martirosyan, followed by a review on Ambartsumian’s life and activity by Jean-Claude Pecker (France), several other talks, and the presentation of V.A. Ambartsumian DVD with full information about the great scientist. The scientific sessions took place on Sep 16-18 in Byurakan.


89 scientists from 12 countries (Armenia, USA, Australia, India, Germany, France, Spain, Poland, Israel, Russia, Ukraine, and Georgia) participated, including such famous astronomers as Jayant Narlikar (India), Jean-Claude Pecker (France), Yervant Terzian (USA), Daniel Kunth (France), Richard Lovelace (USA), Bo Reipurth (USA), and others. There were 38 astronomers from BAO among the participants.


Altogether, 36 oral talks and 8 posters were presented, including 11 invited talks related to the fields of V.A. Ambartsumian’s main achievements (by Bo Reipurth, Yervant Terzian, Davit Sedrakian, Haik Harutyunian / Areg Mickaelian, Richard Lovelace, Daniel Kunth, Igor Karachentsev, Martin Lopez-Coredoira, Jayant Narlikar, Vladimir Grinin, and Arthur Nikoghossian).
