太陽研究者連絡会の皆様、

いつもお世話になっております。神戸大学の政田です。
来週10月31日（月）から11月30日（水）の1ヶ月間、
High Altitude ObservatoryのMatthias Rempel氏が
国立天文台の客員教授として日本に滞在されます。

皆様ご存知かとは思いますが、Rempel氏は太陽の
回転／ダイナモに関する理論的研究や、黒点形成の
シミュレーション研究など、太陽研究の第一線で
活躍されている研究者です。

Rempel氏の滞在に合わせ、以下のスケジュールで
extended office hourや特別講義の開講、mini-workshop
開催を予定しております（mini-workshopについては
別途詳細をご連絡致します）。

■講義予定&Abstract：
■Lecture 1 ~ Basics of Solar Interior Physics and Dynamo ~
(Reference: Heliophysics,chap.3, Cambridge Univ. Press.2009)
7,Nov. ①10:30AM~, ②1:30PM~

Abstract of Lecture 1
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
In the first half of this lecture will present a general introduction 
to dynamo theory, which will be based on a summer school lecture for 
graduate students. This introduction will cover the basic properties 
and definition of large scale dynamos and will introduce mean field 
theory. In the second half I will focus on dynamics of the solar 
interior and cover solar differential including the cycle variation 
known as torsional oscillations. After discussing the role of the 
meridional flow in the angular momentum transport balance I will give 
an overview of solar dynamo models. Since we do not have an generally 
accepted dynamo model at this point, I will present the different dynamo 
scenarios considered to date and discuss the limitations of the various 
modeling approaches that are in use.

■Lecture 2 ~ Solar Surface Physics ~
14,Nov. ①10:30AM~, ②1:30PM~ 
15,Nov. ①10:30AM~, ②1:30PM~
21,Nov. ①10:30AM~, ②1:30PM~
Abstract of Lecture 2
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
In this lecture I will first summarize the physics that govern photospheric 
MHD and briefly discuss the numerical treatment of the resulting equations. 
After discussing in particular the numerical challenges of sunspot simulations,
I will focus on the origin of penumbral fine structure and Evershed flow in 
simulated sunspots. Toward the end of this lecture I will focus on larger 
scales up to the scale of active regions. Here I will focus on the subsurface 
magnetic field and flow structure of sunspots and implications for helioseismic 
studies. On the scale of active regions I will present most recent flux 
emergence simulations showing sunspot formation and decay.

■Extended Office Hour:
趣旨：Rempelさんに天文台内外の皆さんの研究内容を
紹介して頂き、その内容について議論する場を設けます。
