A Tight Upper Limit on Oscillations in the Ap star Epsilon Ursae Majoris from WIRE Photometry
Alon Retter, Timothy R. Bedding, Derek L. Buzasi +2
Observations of Epsilon UMa obtained with the star tracker on the Wide Field Infrared Explorer (WIRE) satellite during a month in mid-2000 are analyzed. This is one of the most pre…
VLT/NACO infrared adaptive optics images of small scale structures in OMC1
Francois Lacombe, Eric Gendron, Daniel Rouan +10
Near-infrared observations of line emission from excited H2 and in the continuum are reported in the direction of the Orion molecular cloud OMC1, using the European Southern Observ…
Sulphur and zinc abundances in Galactic stars and damped Lyman-alpha systems
P. E. Nissen, Y. Q. Chen, M. Asplund +1
High resolution spectra of 34 halo population dwarf and subgiant stars have been obtained with VLT/UVES and used to derive sulphur abundances from the 8694.0, 8694.6 A and 9212.9,…
Empirically Constrained Color-Temperature Relations. II. uvby
J. L. Clem, D. A. VandenBerg, F. Grundahl +1
(Abriged) A new grid of theoretical color indices for the Stromgren uvby photometric system has been derived from MARCS model atmospheres and SSG synthetic spectra for cool dwarf a…
Ultra-high-precision velocity measurements of oscillations in alpha Cen A
R. Paul Butler, Timothy R. Bedding, Hans Kjeldsen +5
We have made differential radial velocity measurements of the star alpha Cen A using two spectrographs, UVES and UCLES, both with iodine absorption cells for wavelength referencing…
Heavy elements abundances in turn-off stars and early subgiants in NGC 6752
G. James, P. Francois, P. Bonifacio +12
High resolution spectra (R > 40 000) for 9 main sequence turn-off stars and 9 subgiants in the globular cluster NGC 6752 were acquired with UVES on the VLT-Kueyen (UT2). These data…
