The seismology programme of CoRoT [PDF]
"The CoRoT Mission", (Eds) M. Fridlund, A. Baglin, J. Lochard & L.
Conroy, ESA Publications Division, ESA Spec.Publ. 1306 (2006), p. 39-50, 2008 We introduce the main lines and specificities of the CoRoT Seismology Core Programme. The development and consolidation of this programme has been made in the framework of the CoRoT Seismology Working Group. With a few illustrative examples, we show how CoRoT data will help to address various problems associated with present open questions of stellar ...

, 2018 Over the past few decades, the potential of collocated measurements of 6C data (3C of translational and 3C of rotational motion) has been demonstrated in global seismology using high-sensitivity, observatory-based ring laser technology.

The influence of observation environment on background noise level of gPhone gravimeter
Geodesy and Geodynamics, 2017 Based on the observations of 36 gPhone gravimeters in 2015, the background noise levels in the seismic frequency band (200–600s) and sub-seismic band (1–6 h) are calculated.

The behavior of transverse waves in nonuniform solar flux tubes. II. Implications for coronal loop seismology [PDF]
, 2013 Seismology of coronal loops using observations of damped transverse oscillations in combination with results from theoretical models is a tool to indirectly infer physical parameters in the solar atmospheric plasma. Existing seismology schemes based on approximations to the period and damping time of kink oscillations are often used beyond their ...

Coronal Loop Seismology Using Standing Kink Oscillations With a Lookup Table
Frontiers in Astronomy and Space Sciences, 2019 The transverse structure of coronal loops plays a key role in the physics but the small transverse scales can be difficult to observe directly. For wider loops the density profile may be estimated by forward modelling of the transverse intensity profile.

Giant planets seismology [PDF]
Symposium - International Astronomical Union, 1997 The giant planets Jupiter and Saturn belong to the interesting category of possible goals for remote seismic analysis. Their first seismic observations and their analysis were attempted in 1987 and 1991 respectively, under Philippe Delache's initiative.

Frequency dependent attenuation of seismic waves for Delhi and surrounding area, India
Annals of Geophysics, 2015 The attenuation properties of Delhi & surrounding region have been investigated using 62 local earthquakes recorded at nine stations. The frequency dependent quality factors Qa (using P-waves) and Qb (using S-waves) have been determined using the ...

Ionospheric disturbances around the time of the Ms7.0 Lushan earthquake
Geodesy and Geodynamics, 2013 Variations of Vertical Total Electron Content (VTEC) in the ionosphere are investigated around the time of the Ms7. 0 Lushan earthquake. A time-series analysis shows an anomalous VTEC increase 15 days before as well as some anomalous VTEC decreases 5 ...

Building damages in Deyang city by the 2008 Wenchuan earthquake
Geodesy and Geodynamics, 2011 The Ms8.0 Wenchuan earthquake in 2008 caused huge casualties, economic losses, and building damages, which are analyzed. The results show that damages of houses designed according to the current seismic code were significantly smaller than those without ...

4th Hinode Science Meeting: Unsolved Problems and New Insights ASP
Conference Series, Vol. 455, pp. 211-218 (2012), 2012 Given the difficulty in directly determining prominence physical parameters from observations, prominence seismology stands as an alternative method to probe the nature of these structures. We show recent examples of the application of magnetohydrodynamic (MHD) seismology techniques to infer physical parameters in prominence plasmas.
