The stellar system HIP 101227: is it a binary, a triple or a quadruple system?
Zahra Talal Yousef, Adlyka Annuar, Abdallah Mohammad Hussein +4
In this paper, we present the analysis of the stellar system HIP 101227 to determine the actual number of components in the system, and their properties. We use dynamical modeling…
Physical and geometrical parameters of CVBS XIV: The two nearby systems HIP 19206 and HIP 84425
Mashhoor A. Al-Wardat, Enas Abu-Alrob, Abdallah M. Hussein +6
The data release DR2 of Gaia mission was of great help in precise determination of fundamental parameters of Close Visual Binary and Multiple Systems (CVBMSs), especially masses of…
Comparison of Gaia and Hipparcos parallaxes of close visual binary stars and the impact on determinations of their masses
Mashhoor Ahmad Al-Wardat, Abdallah M. Hussein, Hamid M. Al-Naimiy +1
Precise measurement of the fundamental parameters of stellar systems, including mass and radius, depends critically on how well the stellar distances are known. Astrometry from spa…
The Nucleosynthesis and Reaction Rates of Fluorine 19 () in the Sun
Mohammad K. Mardini, Nidal Ershiadat, Mashhoor A. Al-Wardat +4
We investigate the abundance of in the Sun through the nucleosynthesis scenario. In addition, we calculate the rate equations and reaction rates of the nucleosynthesis of…
Physical and Geometrical Parameters of CVBS X: The Spectroscopic Binary Gliese 762.1
Suhail G. Masda, Mashhoor A. Al-Wardat, Ralph Neuhäuser +1
We present the physical and geometrical parameters of the individual components of the close visual double-lined spectroscopic binary system Gliese 762.1, which were estimated usin…
The United Nations Basic Space Science Initiative: The TRIPOD concept
M. Kitamura, D. Wentzel, A. A. Henden +8
Since 1990, the United Nations is annually holding a workshop on basic space science for the benefit of the worldwide development of astronomy. Additional to the scientific benefit…
