EDITORIAL We are pleased to finalize Issue No. 40 of the Be Star Newsletter. Following our recent practice we assemble an issue after we have accumulated about 50{60 pages of material on our website. The Newsletter continues to be organized in the following sections: Working Group Matters, What's Happening, Abstracts, and information on meetings of interest to the active B star community. Issue No. 40 contains more than fifteen items in What's Happening and forty abstracts of published papers. In Working Group Matters we include the proceedings from the meeting of the Working Group on Active B stars that was held in Rio de Janeiro, Brazil in August 2009. It was at this meeting that the by-laws for the Working Group were finally formalized. Research interests of the Working Group members are summarized in the triennial reports for 2006{ 09 and 2009{12. Our understanding of the activity in B stars, including the Be phenomenon continues to deepen. From high-resolution interferometry to state-of-the-art modeling codes researchers are learning more about the nature of Be star disks. The MiMeS (Magnetism in Massive Stars) collaboration is revealing important information on the origin of magnetic fields in B stars and their role in generating short-term activity and controlling evolution. The Kepler, CoRoT, and MOST spacecraft continue to produce high-quality photometry over long baselines in time. Combined with spectroscopic data these observations reveal a rich set of pulsational frequencies and modes from which constraints can be placed on the internal rotation, metallicity, and the nature of sub-photospheric convection. The high point of the past triennium was IAU Symposium No. 272 (Active OB Stars: Struc- ture, Evolution, Mass-Loss, and Critical Limits) held in Paris, France from 2010 July 19{23. The editors of the Newsletter would like to thank Coralie Neiner for this very successful and enjoyable meeting. Congratulations Coralie! Since traditionally the cover graphic of the Newsletter has been either a novel observation, new theoretical model, or an illustra- tion representing the pulse of contemporary research, the logo for IAUS 272 seemed to be a natural for Issue No. 40. It was great to see and talk with so many colleagues at this meeting. The editors wish to thank all who contributed to this issue. We continue to post short articles and abstracts on our website as they are accepted (http://www.astro.virginia.edu/∼dam3ma/benews/). Please send new contributions by email to [email protected]. We prefer LaTeX format and require that abstracts be submitted as a LaTeX file using the template provided on our website. We encourage you to contribute to our Community Comments section that we introduced in Issue No. 38. In an open forum researchers have the opportunity to voice their opinions on scientific issues and terminology that will become part of the published literature such as one finds in unedited discussion in conference proceedings. We appreciate the continuing support from the Department of Physics & Astronomy at Georgia State University for the production of the paper edition of the Be Star Newsletter.

Meeting of the Working Group on Active B Stars at the 27th IAU General Assembly in Rio de Janeiro, Brazil: Call for Contributed Talks The Working Group on Active B stars has been allocated three hours (2 sessions) for a business and scientific meeting at the forthcoming IAU General Assembly in Rio de Janeiro. The meeting is scheduled from 09:00{10:30 and 11:00{12:30 on Thursday, August 6, 2009. The IAU GA will be held in the new SulAm´ericaConvention Center. Our room assignment will announced in May. As usual the business meeting should be short, leaving nearly 2.5 hours for scientific talks. If you would like to present a talk during this meeting, please send us a title for your presentation ASAP. We welcome longer, research-oriented talks as well as brief announcements or updates on current activities of interest to the Working Group members. We envision presentations lasting from 5{30 minutes, including discussion. We plan to publish the proceedings of the business and scientific meetings in the Be Star Newsletter. Please submit your title and the requested time for your presentation to: [email protected]. Note that early on-line registration for the IAU GA ends on May 1. We are looking forward to seeing you in Rio in August. Breaking News The IAU has just announced that our proposal to hold a symposium on active OB stars in Paris in mid-July of 2010 has been accepted, so please SAVE THE DATE! IAU S272 \Active OB stars: structure, evolution, mass loss, and critical limits" will take place from 2010 July 19-23.
