This award supports visits over a three year period by the various investigators and a graduate student, including Drs. Alexander Brown, Jeffrey L. Linsky, Stephen A. Drake, and Jay A. Bookbinder of the University of Colorado Boulder to the Australia Telescope National Facility (ATNF) of the CSIRO Division of Radiophysics in Marsfield, NSW, Australia, to work with Dr. Ronald T. Stewart. The investigators will study stellar radio emission with an array of radio telescopes called the Australia Telescope (AT). They will exploit the potential of the AT through a collaboration combining their experience of observing radio stars using the Very Large Array (VLA) with the capabilities of this new instrument. The Americans will make two collaborative research visits each year during a three year period to study the coronae and winds of a broad range of stars located in almost all parts of the H-R diagram and ranging in age from pre-main sequence stars to the late stages of stellar evolution. These investigations of both thermal and nonthermal radio emission processes in stellar atmospheres are logical extensions of their current research.

该奖项支持各种研究人员和研究生（包括博士）在三年内的访问。科罗拉多大学博尔德分校的 Alexander Brown、Jeffrey L. Linsky、Stephen A. Drake 和 Jay A. Bookbinder 前往位于澳大利亚新南威尔士州马斯菲尔德的 CSIRO 放射物理部澳大利亚国家望远镜设施 (ATNF)，与 Ronald T. Stewart 博士合作。 研究人员将使用一系列称为澳大利亚望远镜（AT）的射电望远镜来研究恒星射电发射。 他们将通过合作，将使用甚大阵列 (VLA) 观测射电星的经验与这种新仪器的功能相结合，充分发挥 AT 的潜力。 美国人将在三年期间每年进行两次合作研究访问，以研究位于赫罗图几乎所有部分的各种恒星的日冕和星风，这些恒星的年龄范围从前主序星到恒星演化的后期阶段。 这些对恒星大气中热和非热射电发射过程的研究是他们当前研究的逻辑延伸。
