Abstract: ALMA, the Atacama Large Millimetre/submillimetre Array, has begun science operations after more than a decade of development and construction. Although the observatory has not yet reached its full capability, it is already making important new discoveries. In the area of low mass star formation, ALMA offers very high angular resolution and high sensitivity observations of nearby molecular clouds, the most well-studied of which are in the northern hemisphere. However, it is for studies of the less well-known clouds of the southern sky that ALMA will excel.

One of these molecular cloud complexes lies in the Lupus constellation, and an international consortium of ALMA scientists have begun an effort, the SOLA program, to probe the star formation activity in this region. It turns out that the clouds in Lupus and its star formation has some unique characteristics that make of of great interest for studies of star formation in different environments, particularly for the formation of very low mass stars and brown dwarfs.

Bio: Lewis Knee is a radio astronomer at NRC Herzberg in Victoria. He received his PhD in Radio and Space Science at the Chalmers University of Technology in Sweden in 1991. Since then he has worked in radio astronomy observatories in Europe, Canada, and Chile, most recently six years at ALMA in the Atacama Desert. His main scientific interests are in spectroscopy, star formation, molecular clouds, and the interstellar medium of our Galaxy.
