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…

Cosmological Insights into the Early Accretion of \textit{r}-Process-Enhanced stars. I. A Comprehensive Chemo-dynamical Analysis of LAMOST J1109+0754

Mohammad K. Mardini, Vinicius M. Placco, Yohai Meiron +10

This study presents a comprehensive chemo-dynamical analysis of LAMOST J1109+0754, a bright (V = 12.8), extremely metal-poor (\abund{Fe}{H} = ) star, with a strong \textit{r…

Probability Distribution of Magnetic Field Strengths through the Cyclotron Lines in High-Mass X-ray Binaries

Ali Taani, Awni Khasawneh, Mohammad Mardini +2

The study of variation of measured cyclotron lines is of fundamental importance to understand the physics of the accretion process in magnetized neutron star systems. We investigat…

On the possibility of disk-fed formation in supergiant high-mass X-ray binaries

Ali Taani, Shigeyuki Karino, Liming Song +3

We have considered the existence of neutron star magnetic field given by the cyclotron lines. We collected the data of 9 sources of high-mass X-ray binaries with supergiant compani…
