The unique capabilities of HST for stellar physics: Probing Atmospheric Structure, Chromospheres, and Mass Loss of Evolved Stars
Maryam Saberi, Graham Harper, Jacco Th. van Loon +10
Evolved stars are among the primary sources of chemical enrichment and dust production in galaxies. During the giant phases, stars return a substantial fraction of their mass to th…
HST observations of chromospheric UV lines in the AGB star R Leo
Maryam Saberi, Donald G. Luttermoser, Graham M. Harper +3
The role of stellar chromospheres in the chemistry, mass loss, and evolution of cool evolved stars remains poorly understood. We present high-resolution ultraviolet spectra of the…
Radio Emissions from Substellar Companions of Evolved Cool Stars
R. Ignace, M. L. Giroux, D. G. Luttermoser
A number of substellar companions to evolved cool stars have now been reported. Cool giants are distinct from their progenitor Main Sequence (MS) low-mass stars in a number of ways…
Infrared Light Curves of Mira Variable Stars from COBE DIRBE Data
Beverly J. Smith, D. Leisawitz, M. W. Castelaz +1
We have used the COBE DIRBE database to derive near- and mid-infrared light curves for a well-defined sample of 38 infrared-bright Mira variable stars, and compared with optical da…
Phase Dependent Spectroscopy of Mira Variable Stars
Michael W. Castelaz, Donald G. Luttermoser, Daniel B. Caton +1
Spectroscopic measurements of Mira variable stars, as a function of phase, probe the stellar atmospheres and underlying pulsation mechanisms. For example, measuring variations in T…
