Figure

Figure 2. Color excess ratios as a function of stellar parameters, shown for isochrones (gray shading) spanning a range of age (4–14 Gyr), metallicity ( −2.3  [Fe/H]  0.5), and reddening (0  A V  3.1 mag)
Figure 4. Same as in Figure 3, but for giant stars.
Figure 5. Isochrone for an 8 Gyr population with [Fe/H] = −0.4 at 7.2 kpc with E(B − V ) = 0.64 mag (gray curve)

This doctoral thesis provides a health overview for the Palestinian population in regard to factors relating to quality of life and the prevalence of depression in patients

Method: This article aims to bring some order to the polysemy and synonymy of the terms that are often used in the production of graphic representations and to

of Hubble type, and galaxy stellar mass, M ?. The goals are: 1) to characterize in detail the radial structure of stellar population properties of galaxies in the local universe; 2)

Recent observations of the bulge display a gradient of the mean metallicity and of [Ƚ/Fe] with distance from galactic plane.. Bulge regions away from the plane are less

That is, local MS stars located at a dis- tance shorter than ∼2.5 kpc are not affected by the presence of the star-forming region G61.48 +0.09, but more distant MS stars have

This comparison supports the idea that the asymmetry in the distribution of projected axis ratios is an indication of a large population of intrinsically elongated galaxies

Thus, our objectives are to provide i) an accurate derivation of the oxygen abundance from the single-ratio indicators O3N2 and N2 anchored to direct abundance measurements.

Abstract: We propose a rigorous and effective way to compare experimental and theoret- ical histograms, incorporating the different sources of statistical and systematic
