The nonlinear development of the kink instability in a horizontal magnetic flux tube with a field strength exceeding the equipartition value lying initially in the deep convective zone is calculated. A Lagrangian numerical code is developed to obtain solutions for the system of equations dictating the evolution of a thin magnetic flux tube in a

Using the Coudé Echelle Spectrograph fed by the 1.4 m Coudé Auxiliary Telescope at ESO, La Silla, the authors have obtained a sequence of fourteen high resolution (λ/Δλ = 105) spectra at high signal to noise ratio, of main sequence and near main sequence objects in the wavelength range containing the 6708 Å resonance doublet of lithium. Using

Studying a sample of late-B fast rotators, the authors have detected narrow absorptions of C IV and Si IV in the direction of six stars within 200 pc of the sun. The features are faint and narrow and in a few cases superimposed on broader and more complex profiles. It is not yet clear if they originate in the surroundings of the star or in the
