Strömgren photometry in globular clusters : M 55 & M 22 ⋆
We present Strömgren CCD photometry for the two galactic globular clusters M55 (NGC 6809) and M22 (NGC 6656). We find average Strömgren metallicities of −1.71±0.04 dex for M55 and −1.62 ± 0.08 dex for M22. The determination of metal abundances in cluster giants with the Strömgren m1 index in comparison with spectroscopic data from Briley et al. (1993) and Norris & Freeman (1982, 1983) shows tha...
متن کاملHST Luminosity Functions of the Globular Clusters M 10 , M 22 , and M 55 . A comparison with other clusters . ⋆
From a combination of deep Hubble Space Telescope V and I images with groundbased images in the same bands, we have obtained color–magnitude diagrams of M10, M22, and M55, extending from just above the hydrogen burning limit to the tip of the red giant branch, down to the white dwarf cooling sequence. We have used the color-magnitude arrays to extract main sequence luminosity functions (LFs) fr...
متن کامل5-{40-[(5-Benzyl-2H-tetrazol-2-yl)- methyl]biphenyl-2-yl}-1H-tetrazole monohydrate
In the title compound, C22H18N8 H2O, the dihedral angle between the tetrazole rings is 69.58 (1) while the terminal phenyl ring makes dihedral angles of 26.98 (8) and 39.75 (8) with the other benzene rings. The rings of the biphenyl unit subtend a dihedral angle of 55.23 (8) . In the crystal, the solvent water molecule is linked to the main molecule via an N—H O hydrogen bond. In addition, C—H ...
متن کاملEnergetic derivatives of 5-(5-amino-2H-1,2,3-triazol-4-yl)-1H-tetrazole.
This study presents the preparation of the novel nitrogen-rich compound 5-(5-amino-2H-1,2,3-triazol-4-yl)-1H-tetrazole (5) from commercially available chemicals in a five step synthesis. The more energetic derivatives with azido (6) and nitro (7) groups, as well as a diazene bridge (8) were also successfully prepared. The energetic compounds were comprehensively characterized by various means, ...
متن کاملConcise Synthesis of Tetrazole Macrocycle
A concise two step synthesis of tetrazole containing macrocycles from readily accessible starting materials is presented. The first step comprises a chemoselective amidation of amino acid derived isocyanocarboxylicacid esters with unprotected symmetrical diamines to afford diverse α-isocyano-ω-amines. In the second step, the α-isocyano-ω-amines undergo an Ugi tetrazole reaction to close the mac...
