Comparative seismology of pre- and main sequence stars in the instability strip [PDF]

open access: yes, 2001
Pulsational properties of 1.8 M$_{\odot}$ stellar models covering the latest stages of contraction toward the main sequence up to early hydrogen burning phases are investigated by means of linear nonadiabatic analyses.

Comparative Insights Into the Structural, Electronic, Elastic, Vibrational, and Optical Properties of Rare‐Earth Palladium Borides RBPd3 (R = Lu, Yb)

open access: yesNano Select, EarlyView.
This study focuses on the ground‐state properties of two rare earth palladium borides, LuBPd3 and YbBPd3. The WIEN2k package is used to investigate the properties. The compounds’ exceptional thermal and optoelectronic properties make them suitable for high‐temperature applications, UV absorbers, and infrared (IR) shielding materials.

Combining seismology and spectropolarimetry of hot stars [PDF]

open access: yes, 2014
Asteroseismology and spectropolarimetry have allowed us to progress significantly in our understanding of the physics of hot stars over the last decade. It is now possible to combine these two techniques to learn even more information about hot stars and

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

open access: yesphysica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

A high-precision borehole gravimeter

open access: yesGeodesy and Geodynamics, 2011
The paper describes the working principle and structure of a newly designed high-precision (micro-gal) gravimeter, which is basically a vertically suspending spring-weight system, using a highly sensitive capacitance sensor of movement in a controlled ...

MHD Waves and Coronal Seismology: an overview of recent results

open access: yes, 2012
Recent observations have revealed that MHD waves and oscillations are ubiquitous in the solar atmosphere, with a wide range of periods. We give a brief review of some aspects of MHD waves and coronal seismology which have recently been the focus of ...

The seismic fingerprint of wind‐induced tree sway

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Climate change is increasing the frequency and intensity of extreme events like heat waves, droughts and storms, placing forests under growing physiological and mechanical stress. Common indicators of tree stress, such as sap flow, stomatal conductance, water potential or photosynthetic activity, provide valuable insights but are costly ...

Analysis of Stress Variation Characteristics of Jiangling Depression, Hubei, China, Based on Jingzhou Well Water Level and GNSS Data

open access: yesGeofluids
There have been many M≥3.0 earthquakes in and around the Jiangling Depression in history, and the stress variation can directly affect the preparation of surrounding earthquakes. This paper innovatively uses the variation characteristics of Jingzhou well
