The Second Announcement of an International Workshop on Active OB-Stars: Laboratories for Stellar & Circumstellar Physics August 29 - September 2, 2005 Hokkai-Gakuen University, Sapporo, Japan sponsored by Japan Society for the Promotion of Science and The 21st Century COE Programme on Topological Science and Technology http://www.kwasan.kyoto-u.ac.jp/be2005/ Atsuo Okazaki Hokkai-Gakuen University Toyohira-ku, Sapporo 062-8605, Japan email:  okazaki@elsa.hokkai-s-u.ac.jp Received: 15 March 2005 Dear Colleagues, We are pleased to distribute the second 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. With this announcement we call for papers and encourage you to make formal registration for the workshop, the information for which can be found on the web site http://www.kwasan.kyoto-u.ac.jp/be2005/. Scientific Motivation This workshop aims at bringing together researchers working on Active OB-Stars, exchanging various ideas and enhancing the interaction between participants, utilizing these stars as laboratories for studying the underlying physical processes -- magnetic fields, pulsation, rotation, radiative instabilities, binarity -- with focus on implications for the structure and evolution of the central star, as well as any associated circumstellar envelope, disk, and mass outflow. Such a broad range of physical processes mandates consideration of several specific observational classes of Active OB-stars, including classical Be stars, magnetic Bp stars,  Cephei stars, slowly-pulsating B (SPB) stars, Be X-ray binaries, and B[e] stars. Some of the key issues to be discussed are: What mechanism(s) are responsible for driving material from the stellar surface and the oft-observed reappearance and disappearance of circumstellar emission over times scales ranging from months to years? Under what circumstances is the material propelled directly into an outflowing wind, extended over a broad "cloud'' or confined in a thin disk? Are the processes feeding circumstellar material impulsive or steady? In the case of Be stars, how close is the stellar rotation to the critical rate? Is the development of a disk one common phase in the evolution of rapidly rotating stars, or is it an evolutionary branch? Is rapid rotation an intrinsic consequence of massive star evolution, or might it sometimes depend on external factors like cluster membership, metallicity, or an earlier phase of close binary mass exchange? How does binarity influence the ejection and evolution of circumstellar and/or disk material? Preliminary Programme The workshop is divided in five sessions with different themes. Each session will be composed of invited reviews, contributed oral presentations and posters. The number of invited reviews is small, so as to offer an important space to many contributed talks and thematic discussion sessions, which will take place at the end of each half day. Posters will be at display during the entire workshop and there will be ample time for poster viewing during breaks. Active OB-stars: past, present and future Overview of Active OB-Stars - Stan Owocki Statistical inference of Be star periodicity - Anne-Marie Hubert Dynamical processes Coupling of rotation and pulsation in OB stars - Umin Lee B-field measurements of OB stars - Coralie Neiner Dynamical tides of close binaries - Bart Willems Stellar mass loss as origin of circumstellar material Links between photospheric activity and formation of circumstellar structures of Be stars - Thomas Rivinius Radiatively driven winds of OB stars - Jiri Krticka Structure and dynamics of circumstellar disks Polarimetric observations of the circumstellar matter and their interpretation - Karen Bjorkman Interferometric measurements of fast rotating OB stars and circumstellar disks - Olivier Chesneau Theory vs. observation of circumstellar disks and their formation - John Porter Evolutionary effects in active OB-stars The role of multiplicity - Doug Gies Rotational evolution of massive stars - Georges Meynet Activity of OB stars and their evolution - Wolfgang Glatzel Dedication The meeting will be dedicated to the work of Prof. Mike Marlborough (University of Western Ontario, Canada), Prof. Ryuko Hirata (Kyoto University, 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. Call for Papers Participants who wish to contribute to the workshop are requested to submit the abstract using the abstract submission form on the workshop web page. Oral contributions will be selected by the SOC. The selected authors will be informed by email in due time and the programme will be updated accordingly. The deadline for abstract submission will be May 15, 2005 for oral presentations and those who apply for the financial support. The deadline for poster presentations is June 30, 2005. Location and Transportation Sapporo is the capital of Japan's northernmost island. Conveniently situated close to Sapporo, New Chitose Airport has frequent domestic flights to/from the main international airports at Narita, Haneda, Chubu and Kansai, as well as regular direct flights to several cities overseas. For more information about Hokkaido and the city of Sapporo, please visit http://www.pref.hokkaido.jp/index-e.html and http://www.global.city.sapporo.jp/. Between New-Chitose Airport and JR (Japan Railway) Sapporo Station, the JR airport express train is available between 8 a.m. and 10 p.m. from New Chitose Airport to JR Sapporo Station, and between 6 a.m. and 8 p.m. from JR Sapporo Station to New Chitose Airport. The train runs every 15 minutes. The entire trip takes 36-40 minutes and costs 1,040 JPY (one way). For additional information, please visit New Chitose Airport website at http://www.new-chitose-airport.co.jp/language/english/index.html. The time table for the Rapid Airport Train from New Chitose Airport to Sapporo is available at http://www.jrhokkaido.co.jp/global/e2.html. Public bus services are also available. It costs 820 JPY (one way) and takes about 70-80 minutes between the airport and JR Sapporo Station. Please note that the bus schedule can be greatly affected by traffic conditions. The workshop will be held at Hokkai-Gakuen University, Sapporo. To get to the workshop venue from JR Sapporo Station, it may be convenient to take the Subway TOHO line at the subway station Sapporo beside JR Sapporo Station for FUKUZUMI, then get off at GAKUENMAE station (the third station from the Sapporo station) and follow the way out #3 to find an instruction map to the workshop venue. It takes 5-6 minutes from the subway Sapporo station to Gakuenmae station. Social Events We are planning several social events: Welcoming reception, Excursion tour, and Banquet. For the excursion tour, we plan a half-day guided bus tour to OTARU, where we will visit several places, including the TANAKA brewer, the AOYAMA's honored house, etc. Welcoming reception at Hokkai-Gakuen University 28th August, Evening Fee: free Excursion to OTARU 31st August, Afternoon Fee: 3,000 JPY, which covers business lunch.
