Magnetic Fields and Stellar Surface Structures
2006We discuss the use of high-resolution spectroscopy for studying inhomogeneities on stellar surfaces. Examples of such inhomogeneities include chemical and temperature spots, pulsation waves and magnetic fields. Presence of surface structures reflects important physical processes occurring in much deeper layers than can be observed and, therefore, they ...

Stellar Magnetic Fields: Measurements and Diagnostics
1988Magnetic fields are central to our understanding of surface activity in cool stars. This paper reviews recent progresses in the measurements of photospheric magnetic fields and stresses some of the main difficulties in the analysis of magnetic field observations.

Stellar Magnetic Fields, Origin and Structure
1988The accumulating observational data point clearly to a basic picture of stellar activity dominated by magnetic fields maintained by dynamo action, dependent on the star’s rotation. There is some tentative evidence that in the pre-main sequence phase there is also some primeval magnetic flux, which may be dynamically significant for the T Tauri ...

Stellar Winds, Magnetic Fields and Disks
2013All main sequence stars lose mass via stellar winds. The winds of cool stars like the sun are driven by gas pressure gradient. However, the winds of hot massive stars which tend to be luminous are driven by emitted by the star radiation pressure. Mass loss from such winds are significantly higher.
