Description
Summary:Stellar spectropolarimetry involves the study of magnetic fields on stars through the collection of high-resolution polarised spectra. This field has grown rapidly in recent years with the advent of two new high-resolution echelle spectropolarimeters available to the astronomical community, ESPaDOnS on the 3.6-m Canada France Hawaii telescope and NARVAL on the 2-m Telescope Bernard Lyot. In addition, several groups are now developing new magnetic imaging codes as well as new techniques to recover information from polarised spectra. In light of this a splinter session at Cool Stars XV was organised to present and discuss some of the latest techniques and results in this field. In this paper I attempt to summarise the ideas and results presented at the session.
