Direct Spectroscopic Observations of Clumping in O - Star Winds
We report the detection and monitoring of transient substructures in the radiation-driven winds of five massive, hot stars in different evolutionary stages. Clumping in the winds of these stars shows up as variable, narrow subpeaks superposed on their wide, wind-broadened (optical) emission lines. Similar patterns of emission-line profile variations are detected in the Of stars ζ Puppis and HD9...
متن کاملThe VLT-FLAMES Tarantula Survey VIII. Multiplicity properties of the O-type star population
Context. The Tarantula Nebula in the Large Magellanic Cloud is our closest view of a starburst region and is the ideal environment to investigate important questions regarding the formation, evolution and final fate of the most massive stars. Aims. We analyze the multiplicity properties of the massive O-type star population observed through multi-epoch spectroscopy in the framework of the VLT-F...
متن کاملThe Origins Billions Star Survey: Galactic Explorer
The Origins Billions Star Survey is a mission concept addressing the astrophysics of extrasolar planets, Galactic structure, the Galactic halo and tidal streams, the Local Group and local supercluster of galaxies, dark matter, star formation, open clusters, the solar system, and the celestial reference frame by determining the position, parallax, and proper motion, as well as photometry, for bi...
متن کاملcatena-Poly[[hexakis(μ-4-methylbenzoato)-κ2 O,O′;κ15 O,O′:O-trieuropium(III)]-tris(μ-4-methylbenzoato)-κ2 O,O′;κ6 O,O′:O]
The title europium(III) carboxyl-ate, [Eu(3)(C(8)H(7)O(2))(9)](n), has three independent Eu atoms, two of which are eight-coordinate in a square-anti-prismatic coordination geometry, whereas the third is nine-coordinate in a tricapped trigonal-prismatic coordination geometry. The metal atoms are linked by two bidentate and seven tridentate methyl-benzoate groups into a linear chain running alon...
متن کامل[N,N′-Bis(3-methoxy-2-oxidobenzylidene)ethylenediammonium-κ4 O,O′,O′′,O′′′]tris(nitrato-κ2 O,O′)dysprosium(III)
In the title mononuclear Schiff base complex, [Dy(NO(3))(3)(C(18)H(20)N(2)O(4))], the Dy(III) ion is ten-coordinated in a distorted hexa-deca-hedral geometry by six O atoms of three nitrate anions and four O atoms of the Schiff base ligand. An intra-molecular N-H⋯O hydrogen bond occurs. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
