Top] [Prev] [Next] . Serpens SVS 20 is a binary pre-main sequence star, whose components are separated by 1.5 arcsec. Although of very different brightness, both components have the same spectral energy distribution in the range 0.9 to 5 microns. Eiroa and Casali (1992) discovered that SVS 20 had a arc-shaped nebulosity, departing from the binary star towards the southwest. ...

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. ...

When built, the system needs between 500 and 650 MB disk space (without source) making it ideal for distribution on CD-ROM. Each component has been individually packaged into an easy-to-install bundle for users to obtain over the Internet via a ``point and click'' WWW interface from the Starlink Software Store. ...
