Normal A0--A1 stars with low rotational velocities. I. Abundance determination and classification
F. Royer, M. Gebran, R. Monier +6
Context. The study of rotational velocity distributions for normal stars requires an accurate spectral characterization of the objects in order to avoid polluting the results with…
Weather in stellar atmosphere: the dynamics of mercury clouds in alpha Andromedae
Oleg Kochukhov, Saul J. Adelman, Austin F. Gulliver +1
The formation of long-lasting structures at the surfaces of stars is commonly ascribed to the action of strong magnetic fields. This paradigm is supported by observations of evolvi…
The HgMn Binary Star Phi Herculis: Detection and Properties of the Secondary and Revision of the Elemental Abundances of the Primary
R. T. Zavala, S. J. Adelman, C. A. Hummel +6
Observations of the Mercury-Manganese star Phi Herculis with the Navy Prototype Optical Interferometer (NPOI) conclusively reveal the previously unseen companion in this single-lin…
The ASTRA Spectrophotometer: A July 2004 Progress Report
S. J. Adelman, A. F. Gulliver, B. Smalley +4
A cross-dispersed spectrophotometer with CCD detector and its automated 0.5-m telescope at the Fairborn Observatory, now under construction, should begin observations in 6 to 9 mon…
The optical spectrum of HR 4049 (includes a line identification from 3650 to 10850ang)
Eric J. Bakker, Frank L. A. Van der Wolf, Henny J. G. L. M. Lamers +3
High-resolution optical spectra (UES/WHT) of the extreme metal-poor post-AGB star HR4049 were obtained at four different orbital phases. The spectra cover the wavelength region fro…
