Minimizing Strong Telluric Absorption in Near Infra-red Stellar Spectra
We have obtained high resolution spectra (R ∼ 25000) of an A star over varying airmass to determine the effectiveness of telluric removal in the limit of high signal to noise. The near infra-red line He I at 2.058μm, which is a sensitive indicator of physical conditions in massive stars, supergiants, H II regions and YSOs, resides among pressure broadened telluric absorption from CO2 and water ...
متن کاملIron abundances from optical Fe iii absorption lines in B-type stellar spectra
The role of optical Fe iii absorption lines in B-type stars as iron abundance diagnostics is considered. To date, ultraviolet Fe lines have been widely used in B-type stars, although line blending can severely hinder their diagnostic power. Using optical spectra, covering a wavelength range ∼ 3560 – 9200 Å, a sample of Galactic B-type main-sequence and supergiant stars of spectral types B0.5 to...
متن کاملAutomated analysis of stellar spectra
Classical model-atmosphere analyses of stellar spectra usually begin by measuring equivalent widths, and then proceed into a loop in which 1) model spectra are calculated for a set of abundances and atmospheric parameters, and 2) observed and computed spectra are compared and corrections to the abundances and parameters are inferred. Automated techniques have been developed to automate the meas...
متن کاملStellar Rotation from GAIA Spectra
Abstract. Stellar rotation influences our understanding of stellar structure and evolution, binary systems, clusters etc. and therefore the benefits of a large and highly accurate database on stellar rotation, obtained by GAIA, will be manifold. To study the prospects of GAIA measurement of projected rotational velocities vrot sin i, we use synthetic stellar spectra to simulate the determinatio...
متن کاملResonance-fluorescence and absorption spectra of a two-level atom driven by a strong bichromatic field.
We identify discrepancies between two published predictions of the resonance fluorescence from a two-level atom driven by a strong bichromatic field @J. Opt. Soc. Am. B 8, 1163 ~1991! and Phys. Rev. A 48, 3092 ~1993!#. These discrepancies are shown to arise from subtleties in extracting the time-averaged resonance fluorescence from the expansions used to solve the optical Bloch equations. We co...
