Dear Colleagues,
We are sending you the third announcement of the international
workshop on Active OB-Stars: Laboratories for Stellar & Circumstellar
Physics to be held at Hokkai-Gakuen University, Sapporo, Japan, for
August 29 - September 2, 2005. In this announcement we mainly provide
you the scientific programme and the local information including the
social programme. The first and the second announcements as well as a
list of participants and submitted abstracts are found in the web site
at
http://www.kwasan.kyoto-u.ac.jp/be2005/.
For registration, accommodation, and local transportation, please see
the 2nd announcement or corresponding pages
of the above web site. The next (final) announcement will have more local
information.
DEDICATION
The workshop will be dedicated to the work of Prof. Mike Marlborough
(University of Western Ontario, Canada), Prof. Ryuko Hirata
(University of Kyoto, Japan) and Dr. Anne-Marie Hubert (Observatoire
de Paris-Meudon, France), who all have been pioneers of the physical
modeling of mass-loss and circumstellar disks of Be stars as well as
of their observational studies for several decades. We have also
decided to dedicate the proceedings to the memory of Dr. John Porter,
who died young recently. With his original and brilliant ideas, he has
made a lot of important contributions to this field.
PROGRAMME
The workshop is divided into five sessions with different themes.
Each session will be composed of invited reviews, contributed oral
presentations and discussion sessions, which will take place at the
end of each programme unit. There are three kinds of talks: review
talks (45 min), regular contributed talks (25 min) and short
contributed talks (20 min). Posters, 90cm x 180cm maximum, will be at
display during the entire workshop. There will be ample time for
poster viewing during breaks.
Below is the detail of the sessions.

Kimono Wearing.
A chance is provided for both males and females to try on traditional
Japanese clothing, taking a look at the art of putting on a kimono
plus the history and culture behind its origin. Simple step-by-step
instructions allow even a novice to wear the intricate silk gowns with
dignity, and the resulting photographs will surely serve as a unique
reminder of your time in Japan.
-
Japanese Tea Ceremony (Sado).
Japanese green tea actually originated in China and was brought to
Japan in the 12th century, where it developed into a ceremony that has
become one of the country's traditional art forms. Learn a little of
the history behind sado, or the way of tea, and join in a ceremony
dedicated to the making and drinking of this Zen-influenced drink.

CONFERENCE FACILITIES
The conference room is equipped with a visual presenter for
transparencies (or other materials) and a data projector for
laptops. A laptop, in which Windows XP, PowerPoint and Acrobat Reader
are installed, is also available. If you want to use our laptop, bring
us your files on a USB memory stick or a CD well before your
presentation. Although you can also use your own laptop for your
presentation, it is a good idea to bring a back-up copy of your
presentation on a CD just in case of any incompatibility
problems. There are two screens in the room, so you can use both of
visual presenter and data projector simultaneously.
Posters will remain on display during the whole meeting, along the
corridor outside the conference room. Each poster board is 90cm wide
and 180cm high.
We are planning to make several PCs available for internet connection,
e.g., SSH connection to remote servers and web browsing, at a room
next to the conference room. Since the conference building is shielded
by a firewall and no PC can be connected to the internet without
permission, we will also have a room, in which you can connect your
laptop to the internet, in a building next to the conference
building.
