On the Variability of Blue Straggler Stars in the Globular Cluster M53 [PDF]

Journal of Astronomy and Space Sciences, 1998
We present the results of a search for photometric variable blue straggler stars (BSSs) in the globular cluster M53. Six of the 151 probable BSSs are identified as variable candidates based on the robust variable star detection technique of Welch ...

Poly[bis(μ2-formato-κ2O:O′)(quinoxaline-κN)copper(II)]

Acta Crystallographica Section E, 2008
In the polymeric title copper(II) compound, [Cu(CHO2)2(C8H6N2)]n, both formato ligands are O-bidentate anions and act as bridging ligands, creating a planar polymeric arrangement. The slightly distorted square-pyramidal coordination around CuII comprises

Neutron Resonance Spectroscopy of 104Pd, 105Pd, and 110Pd

, 2002
We have measured neutron resonances in the palladium isotopes 104, 105, and 110 for neutron energies from 1 to 2100 eV. Many new p-wave resonances have been observed. Their neutron widths and, in several cases, the radiative widths were measured.

General form of the deformation of Poisson superbracket on (2,2)-dimensional superspace [PDF]

, 2006
Continuous formal deformations of the Poisson superbracket defined on compactly supported smooth functions on n-dimensional space taking values in a Grassmann algebra with m generating elements are described up to an equivalence transformation for the ...

Dynamical age differences among coeval star clusters as revealed by blue stragglers

, 2012
Globular star clusters that formed at the same cosmic time may have evolved rather differently from a dynamical point of view (because that evolution depends on the internal environment) through a variety of processes that tend progressively to segregate

On hypercharge flux and exotics in F-theory GUTs [PDF]

, 2010
We study SU(5) Grand Unified Theories within a local framework in F-theory with multiple extra U(1) symmetries arising from a small monodromy group. The use of hypercharge flux for doublet-triplet splitting implies massless exotics in the spectrum that ...
