Magnetic Field Measurements on Cool Stars

  • Conference paper

Part of the book series: Reviews in Modern Astronomy ((MOD.ASTRONOMY,volume 4))

Abstract

This review attempts to provide a simple introduction to the measurement of cool-star magnetic fields for the non-specialist. After a short historical overview the basics underlying the measurement of magnetic fields on cool stars are briefly introduced. The special role played by the sun in the study of stellar magnetism is pointed out and illustrated with the help of two examples. Stellar measurements in circularly polarized light are discussed. The Robinson technique for the measurement of stellar fields in unpolarized light is described and the problems associated with it, as well as possible solutions to them, are sketched out. Some trends resulting from the sum of the magnetic field detections on cool stars are discussed. A well observed star, ∈ Eri, is then considered in greater detail. The main conclusions of the talk are summarized.
