The conference starts in the morning of Monday 12 July and ends on Friday 16 July at noon.
The current version of the programme of the oral contributions can be found here.
The abstracts of the posters and oral contributions are available here.

The colloquium will include five thematic sessions:

• Massive star formation, confronting theory and observation
• Evolution and interaction of massive stars with their environment
• Stellar winds, diagnostics across the electromagnetic spectrum
• Massive binaries: interaction and evolution
• Future instrumentations and their application to massive star's research

Invited reviews will be given on the following topics:

• Long-wavelength (mid-IR to mm) studies of massive star formation (Henrik Beuther, Heidelberg)
• The multi-wavelength view of massive star formation in massive clusters (Hans Zinnecker, Potsdam)
• Feedback from massive YSOs and massive main-sequence stars (You Hua Chu, Urbana-Champaign)
• Circumstellar Matter around evolved massive stars (Nathan Smith, Berkeley)
• Evolution of single massive stars with special emphasis on the LBV and RSG phase (Georges Meynet, Geneva)
• Theory of stellar winds (Stan Owocki, Delaware)
• Radio observations of massive stars (Ronny Blomme, Brussels)
• X-rays, clumping and wind structures (Lida Oskinova, Potsdam)
• UV, optical and near-IR diagnostics of massive stars (Fabrice Martins, Montpellier)
• Theoretical models of interacting winds in massive binaries (Julian Pittard, Leeds)
• Results of the 2009 multi-wavelength campaign on eta Carinae (Mike Corcoran, GSFC)
• Results of the 2009 multi-wavelength campaign on WR140 (Peredur Williams, Edinburgh)
• Signatures of binary evolution processes in massive stars (Dany Vanbeveren, Brussels)
• Massive Star Research within the ELT era (Chris Evans, Edinburgh)

Social events:

• On Monday evening, the city of Liège offers a welcome cocktail.
• On Tuesday evening, the participants of the colloquium are invited to visit the workshops of the company AMOS which is specialized in manufacturing mechanical and optical systems for ground-based and space-borne instrumentation. The visit is followed by a reception offered by AMOS.
• On Wednesday afternoon, the participants have the possibility to either participate in various visits or to take a free afternoon.
• Finally, the conference dinner takes place on Thursday evening.
