Advancements in Astronomy and Space Sciences in Jordan: Contributions from Experts and Astrophysical Institutions

open access: yes
Abstract Humanity has always been fascinated by astronomy and space sciences. Two distinct groups of Jordanians show interest in this subject: specialists and amateurs. Experts, often academicians and researchers, immerse themselves in the scientific mysteries of the universe, contributing to global knowledge.

Data-constrained Magnetohydrodynamic Simulation of a Filament Eruption in the Decaying Active Region 13079 on a Global Scale

open access: yesThe Astrophysical Journal
Filaments are special plasma phenomena embedded in the solar atmosphere, characterized by unique thermodynamic properties and magnetic structures. Magnetohydrodynamic (MHD) simulations are useful to investigate the eruption mechanisms of filaments.

Progress of radio occultation exploration of Mars

open access: yes地球与行星物理论评
Mars is the sister star of Earth. Studying Mars is important to understand its evolution as well as that of Earth and even the solar system. Since the launch of American Mariner 4 in 1964 and the first successful use of radio occultation technology to ...

Thermal-timescale accretion does not always yield critical rotation in mass gainers

open access: yesAstronomy & Astrophysics
Binary evolution plays a central role in producing rapidly rotating stars. Previous studies have shown that mass gainers in binaries can reach critical rotation after accreting only modest amounts of material, particularly during thermal-timescale Case B

Carbon monoxide in an extremely metal-poor galaxy

open access: yesNature Communications, 2016
Extremely metal-poor galaxies in the local universe are the best analogues to investigating the interstellar medium at a quasi-primitive environment in the early universe. Here, the authors detect CO emission in a galaxy at 7% solar metallicity, offering

Simulating the Ring-shaped Line-of-sight Flows in Prominence-cavity Systems

open access: yesThe Astrophysical Journal
Line-of-sight oriented flows with several red and blue Doppler-shifted rings in coronal cavities have been observed by the Coronal Multi-channel Polarimeter (CoMP) but rarely explained.

A Multiband Photometric Selection of Period Bouncer Candidates in the Solar Neighborhood with Gaia, GALEX, WISE, eROSITA, and XMM-Newton Data

open access: yesThe Astrophysical Journal
As cataclysmic variables (CVs) that have evolved past their minimum orbital period, period bouncers have been proposed to be a substantial fraction of the CV population, yet the observed number is significantly lower, posing the “missing bouncer” problem.

Enhanced Peak and Extended Cooling of the Extreme-ultraviolet Late Phase in a Confined Solar Flare

open access: yesThe Astrophysical Journal
We present observations and analysis of an X1.8 noneruptive solar flare on 2012 October 23, which is characterized by an extremely large late-phase peak seen in the warm coronal extreme-ultraviolet (EUV) emissions (∼3 MK), with the peak intensity over 1 ...
