Chromospheric Models and the Oxygen Abundance in Giant Stars
A. K. Dupree, E. H. Avrett, R. L. Kurucz
Realistic stellar atmospheric models of two typical metal-poor giant stars in Omega Centauri that include a chromosphere influence the formation of optical lines of Oxygen I: the f…
Direct Evaluation of the Helium Abundances in Omega Centauri
A. K. Dupree, E. H. Avrett
A direct measure of the helium abundances from the near-infrared transition of He I at 1.08 micron is obtained for two nearly identical red giant stars in the globular cluster Omeg…
Mass Outflow from Red Giant Stars in M13, M15, and M92
Sz. Mészáros, E. H. Avrett, A. K. Dupree
Chromospheric model calculations of the Halpha line for selected red giant branch (RGB) and asymptotic giant branch (AGB) stars in the globular clusters M13, M15, and M92 are const…
Absolute Physical Calibration in the Infrared
G. H. Rieke, M. Blaylock, L. Decin +11
We determine an absolute calibration for the MIPS 24 microns band and recommend adjustments to the published calibrations for 2MASS, IRAC, and IRAS photometry to put them on the sa…
The Structured Chromosphere and Wind of TW Hya
A. K. Dupree, E. H. Avrett, N. S. Brickhouse +2
A continuous set of echelle spectra of TW Hya, taken with the MIKE spectrograph on the Magellan2/Clay telescope at Las Campanas Observatory in April 2006 reveals systematic variati…
Identification of the Broad Solar Emission Features Near 117 nm
Eugene H. Avrett, Robert L. Kurucz, Rudolf Loeser
Wilhelm et al. have recently called attention to the unidentified broad emission features near 117 nm in the solar spectrum. They discuss the observed properties of these features…
