The Evolution of Compact Binary Star Systems

open access: yesLiving Reviews in Relativity, 2014
We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Mergings of compact-star binaries are expected to be the most important sources for forthcoming gravitational-wave

Development of thermodynamic database of the Mn‐RE (RE = rare earth metals) binary systems

open access: yesMaterials Genome Engineering Advances
In this work, eight Mn‐RE (RE = Ce, Pr, Sm, Tb, Er, Tm, Lu, and Y) binary systems were reassessed thermodynamically by the CALPHAD method based on the reported optimizations and experimental information.

Thermodynamic predicting of Si-Me (Me = Ti, Al) binary systems [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2007
Thermodynamic predicting analysis of Si-based binary systems - Ti-Si, and Al-Si, are shown in this paper. Thermodynamic analysis involved thermodynamic determination of activities, coefficient of activities, partial and integral values for enthalpies and

Synthesis, Characterization, and Biosorption of Cu2+ and Pb2+ Ions from an Aqueous Solution Using Biochar Derived from Orange Peels

open access: yesMolecules, 2023
In this study, orange peel (OP) biochar was used as a bio-sorbent for the removal of copper and lead from wastewater in single and binary systems. The equilibrium and kinetic studies were conducted at a pH value of 5, which was the maximum adsorption pH ...

Using probabilistic neural network to analyze the binary stars Schulte 3, EY Cep, HD 101131, and Haro 1-14c [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2018
The use of artificial neural networks (ANNs) in physical sciences has increased recently. Determining the orbital elements of binary systems helps us to obtain fundamental information. In this paper, ANNs were used to find the corresponding orbital and

Black Hole Science With the Laser Interferometer Space Antenna

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The author reviews the scientific potential of the Laser Interferometer Space Antenna (LISA), a space-borne gravitational wave (GW) observatory to be launched in the early 30s. Thanks to its sensitivity in the milli-Hz frequency range, LISA will reveal a

Natural Palygorskite as an Industrial Dye Remover in Single and Binary Systems [PDF]

open access: yesMaterials Research, 2016
Layered or fibrous clay minerals are used as adsorbents because they have good performance to remove inorganic and organic species. In this work, a Brazilian fibrous clay mineral was applied to remove Remazol Yellow GR industrial dye from simple and ...
