UNDERGRADUATE SUMMER PROJECT 2008
This summer project is directed at 3rd year undergraduates in the UK who are pursuing a 4-year Physics or Maths-Physics degree. Those who may be interested in pursuing a PhD in space physics after their degree are particularly encouraged to apply. If you are interested in doing this vacation project, please email Claire Foullon by Wednesday 23rd January 2008. If successful, the summer student will receive an undergraduate research bursary from the Royal Astronomical Society or the Nuffield Foundation (£175 a week, for periods of 6-10 weeks). To help with the selection process, please provide the following information (with brief answers):
ABSTRACT Periodic number density structures are known to occur in the solar wind with certain discrete frequencies (0.7, 1.9 and 3.9 mHz) consistent throughout the 11-year solar cycle. They might be frozen-in structures, whose geometries in 3D are still to be determined. In general, mechanims that could vary reconnection on relevant time scales could lead to such periodicities in the solar wind. The source of the periodic number density structures is likely to be found at the Sun. Such events at the Sun are often accompanied by coronal mass ejections (CMEs), which propagate in interplanetary space and may form shock disturbances ahead of the ejecta.In this project, we will study the spatial geometry of periodic number density structures. We will take advantage of the multi-point in situ measurements provided by the new STEREO mission and other spacecraft in the solar wind.
