Red giant seismology: Observations

EPJ Web of Conferences, 2013
The CoRoT and Kepler missions provide us with thousands of red-giant light curves that allow a very precise asteroseismic study of these objects. Before CoRoT and Kepler, the red-giant oscillation patterns remained obscure.

Reconsidering seismological constraints on the available parameter space of macroscopic dark matter [PDF]

Phys. Rev. D 95, 063006 (2017), 2016
Using lunar seismological data, constraints have been proposed on the available parameter space of macroscopic dark matter (macros). We show that actual limits are considerably weaker by considering in greater detail the mechanism through which macro impacts generate detectable seismic waves, which have wavelengths considerably longer than the diameter

ARL‐Unbiased Exponential Control Charts With Estimated Parameters: Statistical Design and Implementation

Quality and Reliability Engineering International, EarlyView.
ABSTRACT The bias of a control chart is an important factor in practical applications. Average run length (ARL)‐biased control charts have their out‐of‐control (OOC) ARL (ARLOOC) greater than the in‐control (IC) ARL (ARLin) for some values of the monitored parameter.

Models of the macroseismic field earthquakes and their influence on seismic hazard assessment values for Central Asia

Геодинамика и тектонофизика, 2020
Seismic intensity assessment in points of a macroseismic scale plays an important role for researching the seismic history of areas characterized by active seismicity, as well as for construction (and updating) of seismic zoning maps in various scales ...

Using coronal seismology to estimate the magnetic field strength in a realistic coronal model

, 2015
Coronal seismology is extensively used to estimate properties of the corona, e.g. the coronal magnetic field strength are derived from oscillations observed in coronal loops.

A statistical investigation of pre-earthquake ionospheric TEC anomalies

Geodesy and Geodynamics, 2011
Previous researches show that the total electron content (TEC) in the ionospheric exhibits anomalous disturbances a few days or hours prior to earthquakes.

Radio seismology of the outer solar corona [PDF]

, 2013
Observed oscillations of coronal loops in EUV lines have been successfully used to estimate plasma parameters in the inner corona (< 0.2 R_0, where R_0 is the solar radius).

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

Geofluids
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

Standing kink waves in sigmoid solar coronal loops: implications for coronal seismology [PDF]

, 2020
Using full three-dimensional magnetohydrodynamic numerical simulations, we study the effects of magnetic field sigmoidity or helicity on the properties of the fundamental kink oscillation of solar coronal loops. Our model consists of a single denser coronal loop, embedded in a plasma with dipolar force-free magnetic field with a constant alpha ...
