Flux tube dynamics and solar/stellar redshift measurements,n. These downflows could be the result either of the cooling and downfall of material in coronal loops or of the steady end-to-end flow of plasma in smaller loops. Time-dependent numerical simulations suggest that the steady flow explanation is the most likely.

The photospheric magnetic fields of cool stars: Recent results of survey and time-variability progrve been employed, producing a considerable body of data on the mean magnetic field strength in stellar active regions (B) and the fraction (filling factor = f) of the stellar surface covered by these fields (f) for G, K, and M dwarfs. I focus on some of the recent results of observational programs a

Calibration on the sun for stellar magnetic fields,roperty to detect the presence of global magnetic fields on sun - like stars. We have obtained a large number of K line profiles over a variety of plages on the sun and related the 1A emission flux centred at the K3 minimum for these profiles with the corresponding values of the longitudinal compone

Large scale solar and stellar magnetic fields,gnetic fields in a wide class of stars has been greatly improved. Calculations of large scale (global) magnetic fields will be presented that utilize sequences of models of a rotating star (the Sun) that take into account differential rotation and meridional circulation. The influence of various mag

The dynamics of solar magnetic flux tubes subjected to resonant foot point shaking,isplacements of solar surface regions of much larger than granular size with a periodicity of the five minute oscillation. We investigate the time-dependent development of waves in thin magnetic flux tubes generated by this purely transverse foot point shaking. The resulting magnetic field and veloc

MHD wave energy fluxes for late-type dwarfs,the assumption that the embedded magnetic fields are uniform. In contradiction with previous results, we show that there is no significant increase in the efficiency of wave generation because of the presence of magnetic fields, at least within the theory‘s limits of applicability. Thus, we show tha

Nonthermal phenomena in stellar coronae: Evidence from radio observations, radio emission is indicative of high energy, nonthermal processes: acceleration of electrons to some 10‘s of keV or, in some circumstances, several MeV or more. These electrons then emit radio waves by the incoherent processes of gyroresonance and gyrosynchrotron radiation, and the coherent process
