Wouter Vlemmings' Homepage

Update: I will be moving to Chalmers Technical University and Onsala Space Observatory to take up an associate professorship and become the head of the Nordic ALMA regional center. As soon as I can I will move the contents of this webpage.

Welcome to my webpage which will likely be forever under construction (whenever I find the time). Old and even older versions of my pages can be found here and here. Several links will still point to me older webpage, but you'll manage to find your way back :).

From beginning 2009 I lead the Emmy Noether group "Magnetic fields during the birth and death of stars" at the Argelander Institute of Astronomy of the University of Bonn in Germany. There I'm also co-manager of one of the European ALMA regional centers. Till the end of 2008, I held an 'Akademischer Rat' university staff position at the AIfA.

Previously I was a Marie Curie Research Fellow working at Jodrell Bank Observatory, which is part of The University of Manchester's Department of Physics and Astronomy. Before that I was a Post-Doc at Cornell University and before that a PhD student at Sterrewacht Leiden.

Massive stars' magnetically controlled diets


A team of astronomers, led by Dr. Wouter Vlemmings at Bonn University, has used the MERLIN radio telescope to show that magnetic fields play an important role during the birth of massive stars. Magnetic fields are already known to strongly influence the formation of lower-mass stars like our Sun. This new study reveals that the way in which high-mass and low-mass stars form may be more similar than previously suspected. (Image credit: Tobias Maercker).

I have been awarded a Deutsche Forschungs Gemeinshaft (DFG) grant to start up an Emmy Noether group "Magnetic fields during the birth and death of stars".

More information on the project can be found at my Emmy Noether group homepage.
