The Indo-U.S. Library of Coudé Feed Stellar Spectra
We have obtained spectra for 1273 stars using the 0.9m Coudé Feed telescope at Kitt Peak National Observatory. This telescope feeds the coudé spectrograph of the 2.1m telescope. The spectra have been obtained with the #5 camera of the coudé spectrograph and a Loral 3K X 1K CCD. Two gratings have been used to provide spectral coverage from 3460 Å to 9464 Å, at a resolution of ∼1Å FWHM and at an ...
متن کاملEstimation of stellar atmospheric parameters from SDSS/SEGUE spectra
We present techniques for the estimation of stellar atmospheric parameters (Teff , log g, [Fe/H]) for stars from the SDSS/SEGUE survey. The atmospheric parameters are derived from the observed medium-resolution (R = 2000) stellar spectra using non-linear regression models trained either on (1) pre-classified observed data or (2) synthetic stellar spectra. In the first case we use our models to ...
متن کاملFundamental Stellar Parameters
I present a discussion of fundamental stellar parameters and their observational determination in the context of interferometric measurements with current and future optical/infrared interferometric facilities. Stellar parameters and the importance of their determination for stellar physics are discussed. One of the primary uses of interferometry in the field of stellar physics is the measureme...
متن کاملQuantitative Stellar Spectral Classification . Iii . Spectral Resolution
The method developed by Stock & Stock (1999) to derive absolute magnitudes and intrinsic colors is applied to simulated low-resolution spectra. The simulation is made by convolving real spectra with a Gaussian function, σ (the full width at half maximum), related to the final spectral resolution. The accuracy with which the stellar parameters are determined indicates that the method may be appl...
متن کاملStellar Atmospheric Parameters: The Four-Step Program and Gaia’s Radial Velocity Spectrometer
The determination of atmospheric parameters is the first and most fundamental step in the analysis of a stellar spectrum. Current and forthcoming surveys involve samples of up to several million stars, and therefore fully automated approaches are required to handle not just data reduction but also the analysis, and in particular the determination of atmospheric parameters. We propose that a suc...
