,Masses of White Dwarfs and Other Remnants: The Ultimate Constraint on Ṁ,sions are that non-explosive loss of about half the initial main sequence mass is fairly universal, that close binaries normally lose more than single stars (though not always much more), and that massive stars lose most during helium burning, while low mass stars (at least in Pop II) lose most duri

Optical Spectroscopy of Red Giants,rincipally because of inadequate knowledge of density, velocity and ionization structure in the circumstellar shells. Improved rates may be expected from binary star systems. Empirical rates derived for stars in globular clusters are found to be of doubtful validity. It is shown that optical observa

Mass Loss in Metal Deficient Red Giants,paper reports several of the results from an observational and theoretical program to assess the presence and character of chromospheric line profiles and their variations, to obtain quantitative measurements of radiative losses from chromospheres, and to construct semi-empirical model chromospheres

Mass Loss from Red Giants: Infrared Spectroscopy,llar envelopes. The molecular bands within this region contain an enormous amount of information, especially when observed with sufficient resolution to obtain kinematic information. In a single spectrum, it is possible to resolve lines from up to 50 different rotational/vibrational levels of a give

CO Vibration Rotation Lines from Circumstellar Shells,tion lines of CO produced by resonance scattering. A novel experimental technique, employing an annular aperture to mask the central infrared continuum source, was used to obtain line profiles at a mean angular offset of 2.7±0.7″ from the center. The results for the carbon-rich Mira variable IRC+102
