Galactic Chemical Evolution, Presolar Grains, and the Solar
Introduction: On the basis of radio measurements, it has been known for close to 30 years that the 18 O/ 17 O ratio is some 25% lower in the interstellar medium (ISM) than in the Solar System [1, 2]. Recent infrared observations of protostars confirm this low ratio in the local ISM [3]. Models of Galactic Chemical Evolution (GCE) have predicted that 18 O/ 17 O should remain constant as the Gala...
متن کاملK dwarfs and the chemical evolution of the Solar cylinder
K-dwarfs have life-times older than the present age of the Galactic disc, and are thus ideal stars to investigate the disc’s chemical evolution. We have developed several photometric metallicity indicators for K dwarfs, based an a sample of accurate spectroscopic metallicities for 34 disc and halo G and K dwarfs. The photometric metallicities lead us to develop a metallicity index for K dwarfs ...
متن کاملGenetic analysis of chemosensory traits in human twins.
We explored genetic influences on the perception of taste and smell stimuli. Adult twins rated the chemosensory aspects of water, sucrose, sodium chloride, citric acid, ethanol, quinine hydrochloride, phenylthiocarbamide (PTC), potassium chloride, calcium chloride, cinnamon, androstenone, Galaxolide™, cilantro, and basil. For most traits, individual differences were stable over time and some tr...
متن کاملThe solar chemical composition
We review our current knowledge of the solar chemical composition as determined from photospheric absorption lines. In particular we describe the recent significant revisions of the solar abundances as a result of the application of a time-dependent, 3D hydrodynamical model of the solar atmosphere instead of 1D hydrostatic models. This has decreased the metal content in the solar convection zon...
متن کاملFunction-valued traits in evolution
Many biological characteristics of evolutionary interest are not scalar variables but continuous functions. Given a dataset of function-valued traits generated by evolution, we develop a practical, statistical approach to infer ancestral function-valued traits, and estimate the generative evolutionary process. We do this by combining dimension reduction and phylogenetic Gaussian process regress...
