Please note that Hans De Sterck, who is one of the speakers at our next gathering on Feb 24, is one of the recipients of the 1999 Outstanding Performance Award for Outstanding Publication of the University Corporation for Atmospheric Research, Boulder, Colorado. His presentation concerns the award winning research.
Here is more information:
The Outstanding Performance Awards of the University Corporation for Atmospheric Research (UCAR), were founded in the 1960s to recognize the highest achievements of UCAR staff.
The Award for Outstanding Publication is given for published results of original research, review papers, pedagogically oriented books, or other contributions to atmospheric science, broadly defined, or for works that connect atmospheric science with other disciplines or with matters of public policy.
The 1999 Award was given in December 1999 to Boon Chye Low and Hans De Sterck (High Altitude Observatory) and Stefaan Poedts (Catholic University of Leuven, Belgium), for their paper:
"Complex magnetohydrodynamic bow shock topology in field-aligned low-beta flow around a perfectly conducting cylinder", Physics of Plasmas 5(11), 4015-4027.
Citation: This paper significantly improves our understanding of the magnetohydrodynamic (MHD) shock structures that form due to high-speed gas and magnetic field outflows from the sun impacting the interplanetary medium and the magnetospheres of the Earth and other planets. The phenomenon of high-speed MHD flow impinging on an obstacle has previously been poorly understood. Through an elegant combination of numerical simulations and ensuing analysis, the authors have brought new and surprising insight into this phenomenon, which occurs in many places in our solar system and, indeed, throughout the universe.
