Meeting on seismology in the solar atmosphere

Sep. 3, 2018

Tomorrow, in La Laguna, sees the start of the BUKS2018 conference, which will bring together for a week 77 specialists in Solar Physics from 14 countries to discuss the latest research on the waves and instabilities which are produced in the atmosphere of the star in our neighbourhood.

Between September 4th and 7th, in the Lecture Theatre Building of the Guajara Campus of the University of La Laguna, there will be a meeting of the seventh BUKS workshop, organized on this occasion by the Instituto de Astrofísica de Canarias (IAC). Its subjects are centred on the study of dynamic phenomena in the solar atmosphere which take the form of magnetic waves and instabilities, from the points of view of theory, observation and plasma diagnostics. “The aim of this meeting -explain Manuel Luna and Iñigo Arregui, researchers at the IAC and the organizers of BUKS2018- is to create a forum for the exchange of ideas and the presentation of the latest results in the field”

During the meeting, which will be attended by 80 participants from research centres in 14 European countries, the US, and Asia, among the topics brought into focus will be the present and future use of installations, instruments, and observational bands, In addition those present will analyse the development and the application of modern methods of data analysis, and comparing these with the most recent models produced in research.

Some current themes which will be tackled during the week are the role of magnetic waves in the heating of the solar corona- the most external and hottest layer of the solar atmosphere- via plasma turbulence phenomena on small scales, large oscillations and Kelvin-Helmholtz instabilities which are observed in solar prominences, the effects of partial ionization in the solar chromosphere- the layer where we find the spicules and prominences characteristic of the Sun, magnetic waves, the improvements in our ability to observe wave phenomena with instruments on the ALMA (Atacama Large Millimeter/submillimeter Array) radiotelescope, and the most recent advances in solar seismology using novel techniques such as Bayesian analysis.

Since in 2009 a number of research centres in Belgium (B) the United Kingdom (UK) and Spain (S) (hence the acronym BUKS) organized the first of these meetings, they have been held in Louvain (BUKS2009, BUKS2016), St. Andrews (BUKS2010), Palma de Mallorca (BUKS2011), Crete (BUKS2012) and Budapest (BUKS2015). This is the first time that the conference has been held in Tenerife, which shows the degree of growth and maturity acquired in recent years by researchers on waves in the solar atmosphere by the group of Solar Physics at the IAC
