Integrating Enterprise Resource Planning (ERP) Systems to Symbiotic Simulation [PDF]

open access: yes, 2014
Symbiotic simulation is inspired by symbiosis in biology and is defined as a close association between a simulation system and a physical system, which is usually beneficial to at least one of them. Many applications have been proposed in recent years

Wide binary stars in the Galactic field : a statistical approach [PDF]

open access: yes, 2010
This thesis focuses on the statistical properties of wide binary (WB) star systems in the Galactic field. With projected separations larger than 200 AU and, consequently, having very low binding energies, WB are sensitive probes of the Galactic ...

The Symbiotics as Binary Stars [PDF]

open access: yesInternational Astronomical Union Colloquium, 1982
AbstractSymbiotic stars have become an important testing ground of various theories of binary star evolution. Several physically different models can explain them, but in each case certain fairly restrictive conditions must be met, so if we manage to identify a definite object with a model, it will tell us a lot about the structure and evolutionary ...

Symbiotic Binary Stars [PDF]

open access: yesSymposium - International Astronomical Union, 1992
This paper briefly reviews the physical properties of symbiotic stars: long-period interacting binaries composed of a red giant primary star and a hot companion. Two types of binaries produce symbiotic optical spectra: semi-detached systems with a main sequence secondary and detached systems with a white dwarf secondary.

New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems [PDF]

open access: yes, 2016
We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orbital elements for the remaining stars because the phase coverage is ...

Gravitoastronomy with neutron stars [PDF]

open access: yes, 2004
Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.
