Mercury's Alfvén Wing Current System Under Sub‐Alfvénic Solar Wind Conditions: Insights From Global MHD Simulations

Geophysical Research Letters
Mercury's proximity to the Sun results in the lowest average Alfvénic Mach number in the upstream solar wind compared to any other planet. Under extreme conditions, the upstream Alfvén speed can exceed the solar wind speed, resulting in a sub‐Alfvénic ...

Connection between Subsurface Layers and Surface Magnetic Activity over Multiple Solar Cycles Using GONG Observations

The Astrophysical Journal
We investigate the spatiotemporal evolution of high-degree acoustic-mode frequencies of the Sun and surface magnetic activity over the course of multiple solar cycles, to improve our understanding of the connection between the solar interior and ...

Recent advances in the interior structure of the gas giants

地球与行星物理论评
Jupiter and Saturn, as the gas giants of our solar system, account for over 90% of the total mass beyond the Sun and hold most of the system's angular momentum, playing a crucial role in the early history of the solar system.

Probing Depth Variations of Solar Inertial Modes through Normal Mode Coupling

The Astrophysical Journal
Recently discovered inertial waves, observed on the solar surface, likely extend to the deeper layers of the Sun. Utilizing helioseismic techniques, we explore these motions, allowing us to discern inertial mode eigenfunctions in both radial and ...

Radial Flow Component of Sun’s High-frequency Retrograde Inertial Waves

The Astrophysical Journal
Solar inertial modes have the potential to surpass the diagnostic capabilities of acoustic waves in probing the deep interior of the Sun. The fulfillment of this potential requires an accurate identification and characterization of these modes. Among the

Multilayer Models for a Differential Rotation of the Sun

The Astrophysical Journal
Differentially rotating multilayer models with the shape of distorted spheroids, so-called spheroidals , are constructed for the Sun. To achieve this, only the observed mass, the gravitational moment J _2 , and the polar and equatorial radii of the Sun ...

CFD Analysis for a New Trombe Wall Concept

Buildings
The envelope (façade) of a building is the first barrier between the exterior and the interior of the building and withstands the highest variation in temperature and solar radiation.
