The influence of opacity on inferred MHD wave signatures in the lower solar atmosphere

Frontiers in Astronomy and Space Sciences
Magnetohydrodynamic wave activity in small-scale magnetic structures, such as solar pores, provides key insights into energy transport in the lower solar atmosphere.

Solar-Like Oscillations in a Massive Star [PDF]

Science, 2009
Star Gazing Seismology of stars provides a unique insight into physical mechanisms taking place in their interior. Like the Sun, some stars have low-amplitude pulsations that are excited by turbulent convection in their outer layers. Belkacem et al. (p.

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

Advanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Evidence of 5 minute Oscillations from Parker Solar Probe

The Astrophysical Journal Letters
The Sun’s surface vibrates in characteristic 5 minute oscillations, known as p -modes, generated by sound waves trapped within the convection zone. Although these oscillations have long been hypothesized to reach into the solar wind, direct in situ ...

A Neptunian mirror for solar oscillations [PDF]

Science, 2017
Asteroseismology![Figure][1] The Kepler satellite PHOTO: NASA AMES/JPL-CALTECH/T PYLE The Sun's brightness varies by a tiny amount because of seismic oscillations. The Kepler satellite has detected the same process on other Sun-like stars, which can be used to determine their mass ...

Solar Mass-Varying Neutrino Oscillations [PDF]

Physical Review Letters, 2005
We propose that the solar neutrino deficit may be due to oscillations of mass-varying neutrinos (MaVaNs). This scenario elucidates solar neutrino data beautifully while remaining comfortably compatible with atmospheric neutrino and K2K data and with reactor antineutrino data at short and long baselines (from CHOOZ and KamLAND).

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films

Advanced Materials, EarlyView.
ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.

A NOTE ON THE TORSIONAL OSCILLATION AT SOLAR MINIMUM [PDF]

The Astrophysical Journal, 2009
We examine the evolution of the zonal flow pattern in the upper solar convection zone during the current extended solar minimum, and compare it with that during the previous minimum. The results suggest that a configuration matching that at the previous minimum was reached during 2008, but that the flow band corresponding to the new cycle has been ...

Radiative Thermal Management for Extreme Environments: Mechanisms and Design Strategies

Advanced Materials, EarlyView.
In this review, we discuss the fundamental mechanisms of radiative cooling and solar heating, material and structural design strategies, hybrid approaches integrating additional heat transfer pathways, and durability‐oriented designs addressing environmental stresses.
