Barnes–Evans relations for late–type giants and dwarfs
The visual surface brightness of K/M giants and dwarfs with near-solar metallicity differ slightly in agreement with the gravity effects predicted by recent theoretical models. We show that M-dwarfs display also a metallicity dependence of the surface brightness in the infrared K-band in agreement with theory. Based on these results, we present improved Barnes-Evans type relations and estimate ...
متن کاملGAIA Spectroscopy and Radial Velocities
GAIA spectroscopic and radial velocity performancies are reviewed on the base of groundbased test observations and simulations. The prospects for accurate analysis of stellar atmospheres (temperature, gravity, chemical abundances, rotation, peculiarities) and precise radial velocities (single stars, binaries, pulsating stars) are colorful provided the spectral dispersion is high enough. A highe...

abstract a fundamental study of “historio-graphic metafiction” and “literary genres”, as introduced in “new historical philosophy”, and tracing them in the works of julian barnes having studied the two novels, the porcupine and arthur & george, by julian barnes, the researcher has applied linda hutcheon’s historio-graphic metafictional theories to them. the thesis is divided into five cha...
15 صفحه اولOn the accuracy of GAIA radial velocities
We have obtained 782 real spectra and used them as inputs for 6700 automatic crosscorrelation runs to investigate GAIA potential in terms of radial velocity accuracy. We have explored the dispersions 0.25, 0.5, 1 and 2 Å/pix over the 8490–8740 Å GAIA range. We have investigated late-F to early-M stars (constituting the vast majority of GAIA targets), slowly rotating (< Vrot sin i > = 4 km sec )...
متن کاملA Near-infrared Variant of the Barnes-evans Method for Finding Cepheid Distances Calibrated with High-precision Angular Diameters
The advantages of a near-infrared variant of the Barnes-Evans method for estimating distances to Cepheid variables are described and quantiied. A surface brightness-color relation for K photometry and the (V ?K) 0 color index is established using modern , high-precision angular diameters from optical interferometers. Applied to data for the galactic (cluster) Cepheid U Sgr, this method yields a...
