The puzzling dredge-up pattern in NGC 1978
Michael T. Lederer, Thomas Lebzelter, Sergio Cristallo +3
Low-mass stars are element factories that efficiently release their products in the final stages of their evolution by means of stellar winds. Since they are large in number, they…
Sculpting an AGB Mass-Loss Envelope into a Bipolar Planetary Nebula: High-Velocity Outflows in V Hydrae
Raghvendra Sahai, Ben E. K. Sugerman, Kenneth Hinkle
We have carried out high-resolution spectroscopic observations of the carbon star V Hya, covering the 4.6 micron band of CO. These data, taken over 7 epochs, show that the circumst…
The Differential Rotation of FU Ori
Zhaohuan Zhu, Catherine Espaillat, Kenneth Hinkle +3
The emission of FU Orionis objects in outburst has been identified as arising in rapidly accreting protoplanetary disks, based on a number of observational properties. A fundamenta…
CNO abundances of HdC and RCB stars: a view of the nucleosynthesis in a white dwarf merger
D. A. Garcia-Hernandez, K. H. Hinkle, David. L. Lambert +1
We present high-resolution (R~50,000) observations of near-IR transitions of CO and CN of the five known hydrogen-deficient carbon (HdC) stars and four R Coronae Borealis (RCB) sta…
