Fluorine Abundances in Local Stellar Populations
K. E. Brady, C. A. Pilachowski, V. Grisoni +2
We present the first fluorine measurements in 12 normal giants belonging to the Galactic thin and thick disks using spectra obtained with the Phoenix infrared spectrometer on the 2…
Variability in Proto-Planetary Nebulae: VII. Light Curve Studies of Five Medium-bright, Oxygen-rich or Mixed-chemistry Post-AGB/Post-RGB Objects
Bruce J. Hrivnak, Gary Henson, Todd C. Hillwig +3
We have monitored over a ten-year interval the light variations of five evolved stars with very large mid-infrared excesses. All five objects appear to have oxygen-rich or mixed ox…
Carbon and Oxygen Isotopic Ratios. II. Semiregular Variable M Giants
Thomas Lebzelter, Kenneth H. Hinkle, Oscar Straniero +3
Carbon and oxygen isotopic ratios are reported for a sample of 51 SRb- and Lb-type variable asymptotic giant branch stars. Vibration-rotation first- and second-overtone CO lines in…
Variability in Proto-Planetary Nebulae: IV. Light Curve Analyses of Four Oxygen-Rich, F Spectral-Type Objects
Bruce J. Hrivnak, Wenxian Lu, Kristie A. Nault
We present new light curves covering 14 to 19 years of observations of four bright proto-planetary nebulae (PPNs), all O-rich and of F spectral type. They each display cyclical lig…
