Linking 1D Evolutionary to 3D Hydrodynamical Simulations of Massive Stars
, 2016 Stellar evolution models of massive stars are important for many areas of astrophysics, for example nucleosynthesis yields, supernova progenitor models and understanding physics under extreme conditions.

Angular Momentum Transport in Stellar Interiors [PDF]
, 2018 Stars lose a significant amount of angular momentum between birth and death, implying that efficient processes transporting it from the core to the surface are active.

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

The core helium flash revisited III. From Pop I to Pop III stars
, 2010 Degenerate ignition of helium in low-mass stars at the end of the red giant branch phase leads to dynamic convection in their helium cores. One-dimensional (1D) stellar modeling of this intrinsically multi-dimensional dynamic event is likely to be ...

Radial Stellar Pulsation and 3D Convection. I. Numerical Methods and Adiabatic Test Cases [PDF]
, 2011 We are developing a 3D radiation hydrodynamics code to simulate the interaction of convection and pulsation in classical variable stars. One key goal is the ability to carry these simulations to full amplitude in order to compare them with observed light

On the Coupling between Helium Settling and Rotation-induced Mixing in Stellar Radiative Zones. III. Applications to Light Elements in Population I Main-Sequence Stars [PDF]
, 2003 In the two previous papers of this series, we have discussed the importance of the μ-gradients due to helium settling in rotation-induced mixing, first in an approximate analytical way, second in a two-dimensional numerical simulation. We have found that,

Advanced Functional Materials, EarlyView.For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Possible Global Magneto-Fluid Structure of the Stellar Convection Zone [PDF]
Publications of the Astronomical Society of Japan, 2006 Structures of the magnetic field and velocity in stars are discussed based on the mean field MHD equations. A special case is presented, where the solution is constructed by the Beltrami solution in the stellar convection zone with the symmetry in the azimuthal direction. Magnetic field lines form concentric toroidal magnetic surfaces.

Convective Overshooting in the Envelopes of A-type Stars Using the k-ω Model
, 2021 Mixing between convective zones is quite uncertain in the envelopes of A-type stars. To study the mixing in A-type envelopes, we use a new convection model, the k-ω model, in the MESA stellar evolution code.
