... Iron abundance in the atmospheres of components of the binary system 41 Draconis . ... 5B Iron abundances, FeI and FeII lines equivalent widths, and microturbulence velocities were found for the components of a highly eccentric spectroscopic and interferometric binary system 41 Dra from high resolution spectra obtained close to the periastron. Weighted mean values of iron abundances in the atmospheres are lgN(Fe) = 7.66 ± 0.03 and lgN(Fe) = 7.72 ± 0.03 for the component a and b, correspondingly. ...

ON THE BELIEVABILITY OF POLAR SPOTS P. BRENDAN BYRNE Armagh Observatory College Hill, Armagh BT61 9DG, N. Ireland Abstract. Polar spots in Doppler Imaging maps of rapidly rotating late­ type stars, especially the active components of RSCVn binaries, represent a major break with the solar paradigm, within which spots are only found at low latitudes. ... Introduction The technique of Doppler Imaging offers the potential to resolve in some detail spot distributions on active late­type stars. ...

Marc White . ... Turbulent entrainment processes may play an important role in the outflows from young stellar objects at all stages of their evolution. In particular, lateral entrainment of ambient material by high-velocity, well-collimated protostellar jets may be the cause of the multiple emission-line velocity components observed in the microjet-scale outflows driven by classical T Tauri stars. ...
