Structures and stabilities of higher coordinate onium-boronium dications (X(+)BH(3)+ and X(+)BH(5)+; X = NH(3), PH(3), H(2)O, and H(2)S).
Structures of higher coordinate onium-boronium dications (X(+)BH(3)+ 1-4a and X(+)BH(5)+ 1-4d; X = NH(3), PH(3), H(2)O, and H(2)S) were calculated by using the ab initio method at the MP2/6-311+G** level. All of the dications 1-4a contain a four-coordinate boron atom with a three-center two-electron bond involving boron and two hydrogens. On the other hand, all the dications 1-4d contain a six-...
متن کاملBoron-induced hydrogen localization in the novel metal hydride LaNi(3)BH(x) (x = 2.5-3.0).
The crystal structure and hydrogenation properties of the intermetallic boride LaNi(3)B were investigated. The hydrogen-free compound has a novel structure with orthorhombic symmetry, space group Imma, a = 4.9698(8) A, b = 7.1337(8) A, c = 8.3001(9) A, and V = 294.26(7) A(3). Thermal gravimetrical analysis reveals a hydride phase that forms near ambient conditions within the compositional range...
متن کاملForty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
متن کاملASCA Observations of NLS1s: BH Mass Estimation from X-ray Variability and X-ray Spectra
ASCA observations of Narrow-Line Seyfert 1 galaxies (NLS1s) are presented. We focus on the black hole size of the NLS1 sources by employing two independent methods for the mass estimation; one is using X-ray variability, the other is using a blackbody fit to the soft component. Although the coincidence is not good for some sources, the mass estimated by these methods ranges from 10 to 10 M⊙, sy...
متن کاملIc10 X-1: the Immediate Progenitor of a Double Black Hole Binary
We follow the evolution of IC10 X-1, the extragalactic binary hosting the most massive known stellar black hole with the mass of at least 23 M⊙. A massive companion of this black hole is a 35 M⊙ helium star that will very soon form another black hole. We demonstrate that this system will become a close double black hole binary with coalescence time of ∼ 2 − 3Gyr. We estimate that a detection ra...
