Magnetic Webs in Stellar Radiative Zones

The Astrophysical Journal Letters
Rotational evolution of stellar radiative zones is an old puzzle. We argue that angular momentum transport by turbulent processes induced by differential rotation is insufficient, and propose that a key role is played by “magnetic webs.” We define ...

Dynamics of Stellar Systems with Collisions: Eigenvalues and Eigenfunctions in Nearly Collisionless Limit

The Astronomical Journal
We examine the decay of perturbations in an infinite homogeneous self-gravitating model with a Maxwellian distribution function (DF) when weak collisions are present.

A Novel Approach to Identifying Substructures through Analysis of Metallicity Distribution Functions

The Astrophysical Journal
We present a new method for identifying Galactic halo substructures accreted from dwarf galaxies by combining metallicity distribution functions (MDFs) with orbital parameters.

Dark Galactic Subhalos and the Gaia Snail

The Astrophysical Journal
Gaia has revealed a clear signal of disequilibrium in the solar neighborhood in the form of a spiral (or snail) feature in the vertical phase-space distribution.

Tracing the Galactic Origins of Selected Four G-type Stars in the Solar Neighborhood

The Astronomical Journal
We present a multimethod investigation of four metal-poor G-type main-sequence stars to resolve their Galactic origins. By combining high-resolution spectroscopy from PolarBase, photometric/astrometric data from Gaia DR3, and spectral energy distribution
