Second Announcement

Science with Large Solar Telescopes

14 – 16 October 2009, Freiburg, Germany


This workshop addresses the science to be done with solar telescopes of an aperture beyond 1 meter. It is held as a joint EAST-ATST workshop and demonstrates the common interests of the European and US solar physics community toward next-generation, large-aperture solar telescopes. The workshop will summarize the scientific justification of these telescope projects, review the current status of relevant solar physics topics, and establish new insights in solar physics theory that can only be verified with the new large telescopes. The workshop will furthermore present the status of current projects, reviews recent accomplishments with today's large facilities and discuss emerging techniques and tools.

Program Outline

1. New Science Frontiers: What are the scientific objectives with which we justify the expenses of the multi-meter class of solar telescopes? How have these objectives changed due to recent progress of physical insight and how may these objectives change due to future progress? Which discoveries are we expected to obtain with 4m-class telescopes? What do today's theories and numerical simulations tell us that can be verified only with telescopes exceeding today's apertures? To which extent can coordinated observations help improving our understanding of the Sun?

2. Lessons learnt from existing telescopes: In this session, we plan to present strengths and weaknesses of existing telescopes, identify problems and limitations, and discuss how this experience can lead to improvements of existing telescopes, new instrumentation for these and to the design of future telescopes. In order to obtain a more complete picture of today’s high-resolution solar physics, this session will also include presentations on Hinode and Sunrise.

3. Next Generation Large Telescopes: In this session, several large-aperture telescope projects will be presented and the most recent status of planning, design or construction will be given.

4. Tools and Techniques: This section deals with next-generation instrumentation, data acquisition, analysis, and interpretation methods, ranging from adaptive optics to (magnetic field) diagnostic tools and modeling.

On-line registration is mandatory, and is done through the conference web page. Please fill in and submit the corresponding form. The conference fee is 100 Euros and will have to be paid in cash at the registration desk office upon arrival at the conference. Local registration is possible on Tuesday afternoon, during the reception that will be held at KIS, or on Wednesday (all day), at the conference site. The registration fee includes costs for refreshments during coffee breaks, internet access (wireless), and the conference dinner on Thursday. The deadline for on-line registration is 30 September 2009.  We strongly recommend, however, to register early, and to book accommodation.

We strongly recommend to book accommodation as early as possible.  If you book late, you may end up either in a very expensive or are rather remote place (both of which could be really nice).  Freiburg is an attractive place for tourists, and autumn is an attractive time. We offer a list of hotels on the conference web page.

All talks will be published in Astronomische Nachrichten, in a special Proceedings Issue. Publication date will be May/June 2010.  Due to the page limit of an AN issue, manuscripts are limited to four printed pages (in AN style).  Details about submission and deadlines of manuscripts will be provided soon.

University of Freiburg, Physics faculty building (“Physik-Hochhaus”), 1st floor, Lecture room 1. Poster area is in the lobby and the seminar room on that same floor.
