First Announcement Workshop: The Interferometric View on Hot Stars Viña del Mar, Chile, March 2 – 6, 2009 ESO – Univ. de Valparaíso – CTIO Vergara Pier Photo: G.

The venue of the meeting will be in Viña del Mar, Chile. The Workshop is sponsored by ESO, the Universidad de Valparaíso, and the CTIO. More detailed information is available on our web page http://www.eso.org/sci/meetings/IHOT09 or by e-mail to ihot09@eso.org . We encourage you to circulate the announcement among your colleagues. On behalf of the organizers, Thomas Rivinius SCOPE The meeting aims at bringing together hot star and interferometry expertise, both observationally and theoretical, to review the progress made, as well as to to outline current problems in hot star research that are expected to benefit most from interferometric observations. One of the research fields on which interferometry excels has turned out to be hot star astrophysics. Results often have been quickly adopted by the community, providing important quantitative constraints in frontline research topics: Several hot stars have been shown to be very rapidly rotating, in a regime where geometric deformation and gravity darkening become important. Stellar winds have been resolved, like those of eta Car and Wolf-Rayet stars. Circumstellar disks have been tackled on a wide range of phenomena: Gaseous accretion disks around young Herbig stars, decretion disks around Be stars, and dusty disks around B[e] stars and again around Herbig stars. While some of these results, like the critical rotation of Achernar and other stars, were a complete surprise, others, like the prolate wind of eta Car, have been anticipated or at least discussed by theoretical research, but still were hardly expected in the clear and unambiguous form they were finally observed. PROGRAM Oral sessions during the meeting will be held on: High angular resolution techniques The stars (including Cepheids) Stellar winds Circumstellar disks Hot binaries Explosive stars Poster sessions are foreseen. Confirmed speakers include: A. Carciofi, O. Chesneau, M. Curé, W. Hartkopf, S. Kraus, R. Mennickent, A. Merand, F. Millour, C. Neiner, S. Owocki, P. Kervella, J. Rajagopal, M. Schöller, N. Smith, C. Tycner. PRIMER SESSION The Thursday and Friday before the Meeting we will hold an interferometry primer, mainly intended for students, but open to all participants as long as there is space. The scope of the primer is to enable attendants without experience in interferometry first steps to understand and assess the results presented and to develop project ideas for discussion during the meeting. This session will take place on ESO's premises in Vitacura, Santiago. Confirmed lecturers include: A. Quirrenbach, O. Chesneau, A. Mérand, J.B. Le Bouquin, M. Schöller. VENUE The workshop will take place in Viña del Mar, at the Pacific coast of Chile, about 100km west of Santiago. Viña is famous well beyond Chile as a holiday resort. Since the Meeting will take place just after the end of the Chilean holiday season, most of the tourist crowds will have returned home already, but you can still expect pleasant coastal climate. There usually is very little rain in March, if at all. Located just south across the city border of Viña is Valparaíso, one of Chile's most important harbors and an UNESCO world heritage site for its historical importance, natural beauty, and unique architecture. The Meeting will take place in the Hotel San Martín (http://www.hotelsanmartin.cl). Special room fees are available, detailed information about Hotel San Martín and alternatives will be sent later. PROCEEDINGS We will have online conference proceedings, whether these will be published in print depends on funding decisions made towards the end of 2008 only. FINANCIAL MATTERS The workshop fee will be 100 Euro (150 USD, 75000 CLP), and 130 Euro (195 USD, 95000 CLP) for both workshop and primer session. We have some limited financial support for students and young researchers. Chilean students are requested to apply for support by the SOCHIAS before requesting direct support from the organizers. Additional support is available for students attending the primer session. DEADLINES Requests for financial support must be submitted Dec. 1 the latest, together with the abstract of the intended contribution, if any. The deadline for the final registration and abstracts is Dec. 17.
