The Fate of Gaia’s Wide Binaries: Interplay of White-dwarf Recoil and Tidal Interactions

The Astrophysical Journal
White dwarfs (WDs) receive natal velocity boosts of ∼1 km s ^−1 due to recoil from asymmetric mass loss during the late asymptotic giant branch (AGB) stage.

Extreme mass loss during common envelope evolution: The origin of the double low-mass white dwarf system J2102–4145★

Astronomy & Astrophysics
Context. Eclipsing close double white dwarf (WD) systems, by providing precise radii and masses, offer a unique opportunity to directly constrain hydrogen-envelope (MH) retention and test common-envelope (CE) evolution in low-mass stars. Aims. We analyse

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains

Cytoskeleton, EarlyView.
ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.

Adiabatic Mass Loss in Binary Stars. VI. Massive Mass Helium Binary Stars

The Astrophysical Journal
The stability of binary mass transfer is a critical problem for binary evolution. We systematically calculate the adiabatic mass-loss model for naked helium stars with masses ranging from 10 M _⊙ to 80 M _⊙ to study the critical mass ratio ( q _crit ) of

From spherical stars to disk-like structures: 3D common-envelope evolution of massive binaries beyond inspiral

Astronomy & Astrophysics
Self-consistent three-dimensional modeling of the entire common-envelope phase of gravitational wave progenitor systems until full envelope ejection is challenged by the vast range of spatial and temporal scales involved in the problem. Previous attempts were either terminated shortly after the rapid spiral-in with significant amounts of ...

Recent Advances in Pickering Emulsion Templated Phase Change Material Microcapsules: Design, Fabrication, and Multifunctional Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fabrication process of phase change microcapsules using a Pickering emulsion template method and their subsequent applications. The increasing demand for efficient thermal energy storage systems has driven the development of phase change material microcapsules (PCMMs), which provide high energy‐storage density, reversible phase change, and reduced ...

Reassessing the spin of second-born black holes in coalescing binary black holes and its connection to the χeff – q correlation

Astronomy & Astrophysics
Context. The mass ratio q and effective inspiral spin χeff of binary black hole mergers in the Gravitational-Wave Transient Catalog 4.0 (GWTC-4.0) have been reported to display a weaker anticorrelation compared to GWTC-3.0, a feature whose origin has ...

Social Class Discrimination and Academic Success: A Person‐Centered Approach Among Adolescents Disadvantaged in Social Class

Journal of Adolescence, EarlyView.
ABSTRACT Introduction Prior research indicates that social class is strongly associated with academic outcomes such as GPA. However, little work explores the role that social discrimination plays in this relation. This study examined the link between social class discrimination and academic outcomes among high school students.
