A supra-massive population of stellar-mass black holes in the globular cluster Palomar 5
Palomar 5 is one of the sparsest star clusters in the Galactic halo and is best known for its spectacular tidal tails, spanning over 20° across the...

Properties of the accretion disc, jet and disc-wind around Kerr black hole
Relativistic jets and disc-winds are energetic phenomena exhibited by various sources, including Active Galactic Nuclei (AGNs) and black hole X-ray...

Explorations of Extreme Space Weather Events from Stellar Observations and Archival Investigations
Solar eruptions occasionally launch geoeffective interplanetary coronal mass ejections (ICMEs) and high-energy particles. Among them, extreme solar...

Close Binary Stars. VII: On the Evolution of Close Binary Systems
AbstractThe article considers various aspects of the evolution of close binary systems (CBSs). The variation in the orbital parameters of a CBS...

The contribution of winds from star clusters to the Galactic cosmic-ray population
Cosmic rays (CR) are energetic nuclei that permeate the entire Galactic disk. Their existence requires the presence of powerful particle...

Hierarchical mergers of stellar-mass black holes and their gravitational-wave signatures
While most of the compact-binary mergers detected by LIGO and Virgo are expected to consist of first-generation black holes formed from the collapse...

Stellar Evolution up to the Final Stages
The nature of the observed stars has been a subject of discussion and speculation since the early days of civilization. Atomists Leucippus and...

Snapshot of a magnetohydrodynamic disk wind traced by water maser observations
The formation of astrophysical objects of different nature, from black holes to gaseous giant planets, involves a disk–jet system, where the disk...

Exoplanet Population Synthesis with Account for Orbit Variation Due to Stellar Evolution
AbstractIn this paper, the orbital evolution of exoplanets at the late stages of stellar evolution was studied using the population synthesis method....

The Atmospheric Wind of Hot Exoplanets and its Manifestations in Observations: from Energy Estimates to 3D MHD Models
Abstract—The studies of close-orbit gaseous exoplanets—hot Jupiters and warm Neptunes—are reviewed. Transit spectral observations of the Hubble Space...

The X-Ray Emission from Planetary Nebulae
Planetary nebulae, the progeny of low- and intermediate-mass stars, are formed by the interaction of the fast stellar wind from its central star,...

Mass Distribution and “Mass Gap” of Compact Stellar Remnants in Binary Systems
Abstract —The highest critical mass of neutron stars (NSs) was reviewed in the context of equation of state and observational results. It was...

Evolution of the X-ray Binary System Sco X-1
AbstractThe possible evolution of a bright low-mass X-ray binary system Sco X-1 is numerically investigated within the framework of a model assuming...

Strange Afterglows from Embedded GRBs: Reconciling Hypernovae with Slow Decays
The hypothesis that GRBs originate in massive stars has gained popularity in recent times. With this comes the expectation that the afterglow should...
