The metallicity range of variables in M3 [PDF]

, 2003
The recently published spectroscopic metallicities of RR Lyrae stars in M3 (Sandstrom, K., Pilachowski, C. A., and Saha, A. 2001, AJ 122, 3212) though show a relatively wide range of the [Fe/H] values, the conclusion that no metallicity spread is real ...

Chemical and Biological Properties of Quinochalcone C-Glycosides from the Florets of Carthamus tinctorius

Molecules, 2013
Quinochalcone C-glycosides are regarded as characteristic components that have only been isolated from the florets of Carthamus tinctorius. Recently, quinochalcone C-glycosides were found to have multiple pharmacological activities, which has attracted ...

A Statistical Study of the Si IV Resonance Line Parameters in 19 Be Stars

Open Astronomy, 2011
Using the GR model, we analyze the ultraviolet Si IV resonance lines in the spectra of 19 Be stars of different spectral subtypes, in order to detect the presence of absorption components and to analyze their characteristics.

The zCOSMOS 10k-Bright Spectroscopic Sample [PDF]

, 2009
We present spectroscopic redshifts of a large sample of galaxies with I_(AB) < 22.5 in the COSMOS field, measured from spectra of 10,644 objects that have been obtained in the first two years of observations in the zCOSMOS-bright redshift survey.
