We present results of new Monte Carlo calculations made with the DIRTY code of radiative transfer of stellar and scattered radiation for a dusty giant late-type galaxy like the Milky Way, which illustrate the effect of the attenuation of stellar light by internal dust on the integrated photometry of the individual bulge and disk components. ... In addition, we find that the structure of the dusty ISM affects more sensitively the observed magnitudes than the observed colors of both bulge and disk. ...

... Several years ago, John Butler and myself derived the radiative energy output from the `quiet' corona of some twenty odd stars, similar in many ways to our own Sun, and found that there was a one-to-one correspondence with the total amount of energy radiated during flares on these stars over a period of say one day. ... The velocities derived increase from 0 km/s at 20,000K to a red-shift of 10 km/s at 190,000 K for the quiet Sun, and to 15 km/s 100,000 K for the active region. ...

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. ...

The principal goal of this study is to show that the real shape of the initial mass function for low- and intermediate-mass stars differs from the observed one. In particular, comparison of radii of eclipsing binary components and single stars shows a noticeable difference for B0V-G0V components of eclipsing binaries and single stars of the corresponding spectral type. ...
