Oxygen isotopic ratios in intermediate-mass red giants
Thomas Lebzelter, Oscar Straniero, Kenneth Hinkle +2
Context. The abundances of the three main isotopes of oxygen are altered in the course of the CNO-cycle. When the first dredge-up mixes the burning products to the surface, the nuc…
Kepler and the Long Period Variables
Erich Hartig, Jennifer Cash, Kenneth Hinkle +3
High precision Kepler photometry is used to explore the details of AGB light curves. Since AGB variability has a typical time scale on order of a year we discuss at length the remo…
Post-Outburst Observations of V1647 Ori: Detection of a Brief Warm, Molecular Outflow
Sean Brittain, Terrence Rettig, Theodore Simon +4
We present new observations of the fundamental ro-vibrational CO spectrum of V1647 Ori, the young star whose recent outburst illuminated McNeil's Nebula. Previous spectra, acquired…
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…
Near-Infrared Classification Spectroscopy: J-Band Spectra of Fundamental MK Standards
Lloyd Wallace, Michael R. Meyer, Kenneth Hinkle +1
We present a catalog of J-band spectra for 88 fundamental MK standard stars observed at a resolving power of R ~ 3000. This contribution serves as a companion atlas to the K-band s…
Precision Analysis of Evolved Stars
Stephen Ridgway, Rachel Akeson, Ellyn Baines +20
Evolved stars dominate galactic spectra, enrich the galactic medium, expand to change their planetary systems, eject winds of a complex nature, produce spectacular nebulae and illu…
Infrared Spectroscopy of Symbiotic Stars. VII. Binary Orbit and Long Secondary Period Variability of CH Cygni
Kenneth Hinkle, Francis Fekel, Richard Joyce
High-dispersion spectroscopic observations are used to refine orbital elements for the symbiotic binary CH Cyg. The current radial velocities, added to a previously published 13 ye…
