Symbiotic Stars of a starlike object with a spectrum that simultaneously contains cool star features, like TiO molecular bands, and nebular emission lines, like [O .] or more highly ionized features. This suggests the presence of two components: a cool giant star plus a nebula of moderate ionization. The light out

Intrinsically Variable Starse discussed (mainly the . Cepheids, W Vir stars and related groups), while the second part deals with late-type variables, mainly the M, S, and C giants and supergiants, hence stars close to and on the Asymptotic Giant Branch (AGB) in the HR diagram. Few of these latter stars appear to be ‘quasi-con

Chromospheres and Transition RegionsCa . H and K lines and in He . 10 830 ?. While some trends in the properties of stellar chromospheres as a function of spectral type and luminosity (e.g. the Wilson—Bappu effect) were established on the basis of optical data, the field could not advance without observations at shorter wavelengths wh

The Dynamics of Hydraulic Systems,January 26, 1978, it is still operational at the time of writing (end 1986, its ninth year) making it the longest-lived astronomical satellite ever. Although it is now showing some signs of age, its scientific performance is essentially unimpaired; for example, its photometric sensitivity has declin
