Hydrodynamics of the Common Envelope Phase in Binary Stellar Evolution [PDF]

, 2016
The common envelope (CE) phase is critical for the formation of close binary stars with at least one compact star. During this phase, a giant star engulfs its companion, which spirals into the giant’s envelope.

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

A Diverse, Overlooked Population of Type Ia Supernovae Exhibiting Mid-infrared Signatures of Delayed Circumstellar Interaction

The Astrophysical Journal Letters
Type Ia supernovae (SNe Ia) arise from the thermonuclear explosions of white dwarfs in multiple-star systems. A rare subclass of SNe Ia exhibit signatures of interaction with circumstellar material (CSM), allowing for direct constraints on companion ...

Hybrid Simulation–Machine Learning Surrogates for Coordinate‐Based Solar and Wind Energy Yield Assessment in Iraq: A Streamlit Decision‐Support Tool

Energy Science &Engineering, EarlyView.
This study integrates climatic simulations with machine learning to predict solar and wind energy across Iraq. Results show Random Forest excels for solar (R2 = 0.98) and neural networks for wind (R2 = 0.97), enabling a practical web tool for renewable energy planning. ABSTRACT Driven by the global shift away from fossil fuels, solar and wind resources

Evolution Models of CO White Dwarf–Asymptotic Giant Branch Star Merger Remnants

The Astrophysical Journal
Common envelope evolution is a critical but still poorly understood phase in binary evolution. It plays a key role in forming close binaries such as hot subdwarfs, double white dwarfs (WDs), X-ray binaries, and double neutron stars. However, its outcomes

Constraining common envelope evolution in binary neutron star formation with combined galactic and gravitational-wave observations

Monthly Notices of the Royal Astronomical Society: Letters
ABSTRACT Binary neutron stars (BNSs) are among the most interesting sources for multimessenger studies. A number of recently discovered BNSs in the Milky Way by radio telescopes have added new information to the parameter distribution of the Galactic BNSs.

Tatooines Future: The Eccentric Response of Keplers Circumbinary Planets to Common-Envelope Evolution of their Host Stars [PDF]

, 2016
Inspired by the recent Kepler discoveries of circumbinary planets orbiting nine close binary stars, we explore the fate of the former as the latter evolve off the main sequence.

Meniscus‐guided organic semiconductor single crystals: From fluid dynamics to morphology control and multifunctional applications

FlexMat, EarlyView.
Centered on the multiscale meniscus, this review dissects mass transport in meniscus‐guided coating into parallel and lateral components. By analyzing the balance of multiple factors during crystallization, it establishes a clear morphology‐performance relationship.
