ARMENIA HOSTS IAU SYMPOSIUM #365:
“DYNAMICS OF SOLAR AND STELLAR CONVECTION ZONES AND ATMOSPHERES”

On August 21-25, the Byurakan Astrophysical Observatory, together with Lomonosov Moscow State University and the International Astronomical Union (IAU) organized the IAU symposium “Dynamics of Solar and Stellar Convection Zones and Atmospheres” in Yerevan.

This year Armenia hosted an IAU symposium for the 7th time in its history. Armenia, consequently the BAO, had the honor to host symposia in 1966, 1986, 1989, 1998, 2001 and 2013.

The Symposium brought together solar and stellar physicists investigating the dynamics of convection zones and lower atmospheres.

It was dedicated to observational and theoretical aspects of the hydrodynamics and magnetohydrodynamics, both global and local, of the solar and stellar convection zones and lower atmospheres with the inclusion of numerical simulations as a particular branch of theoretical research.

The five-day program included 6 sessions with many captivating talks, discussing topics from differently scaled solar convection and magnetoconvection and models of stellar convection to Miscellaneous subjects.

At the opening of the conference, participants were welcomed by Alexander Getling, Professor of Lomonosov Moscow State University, chairman of the Scientific Organizing Committee of the conference, Ashot Saghyan, the president of the RA National Academy of Sciences (NAS), Mihran Aroian, Representative of the RA Ministry of Economy (USA), Eric Tintrup, deputy ambassador of the Federal Republic of Germany, and Areg Mickaelian, the BAO director, chairman of the Local Organizing Committee of the conference.

In recent decades, the topic has been of great interest among researchers. Thanks to modern observational equipment on orbiting observatories, a large amount of valuable data is now available, which contributes to the progress of research on the subject.

Among the main topics discussed at the conference are heat transfer, solar and stellar differential rotations and meridional rotations, global dynamo, solar and stellar seismology, local processes of magnetic flux generation, sunspots and starspots.
