Directional Time-Distance Probing of Model Sunspot Atmospheres [PDF]
, 2015 A crucial feature not widely accounted for in local helioseismology is that surface magnetic regions actually open a window from the interior into the solar atmosphere, and that the seismic waves leak through this window, reflect high in the atmosphere ...

HELAS Local Helioseismology Activities [PDF]
Communications in Asteroseismology, 2009 The main goals of the HELAS local helioseismology network activity are to consolidate this field of research in Europe, to organise scientific workshops, and to facilitate the distribution of observations and data analysis software. Most of this is currently accomplished via a dedicated website at http://www.mps.mpg.de/projects/seismo/NA4/ .

Helioseismology in a bottle: modal acoustic velocimetry
New Journal of Physics, 2014 Measurement of the differential rotation of the Sunʼs interior is one of the great achievements of helioseismology, providing important constraints for stellar physics. The technique relies on observing and analyzing rotationally-induced splittings of p -

Living Reviews in Solar Physics, 2016 The seismic study of the Sun and other stars offers a unique window into the interior of these stars. Thanks to helioseismology, we know the structure of the Sun to admirable precision. In fact, our knowledge is good enough to use the Sun as a laboratory.

Helioseismology and Beryllium neutrinos [PDF]
Physics Letters B, 1999 We derive a lower limit on the Beryllium neutrino flux on earth, $ (Be)_{min} = 1\cdot 10^9 cm^{-2} s^{-1}$, in the absence of oscillations, by using helioseismic data, the B-neutrino flux measured by Superkamiokande and the hydrogen abundance at the solar center predicted by Standard Solar Model (SSM) calculations. We emphasize that this abundance is

A Spectral Solver for Solar Inertial Waves
The Astrophysical Journal Supplement Series, 2023 Inertial waves, which are predominantly driven by the Coriolis force, likely play an important role in solar dynamics, and, additionally, they provide a window into the solar subsurface.

Correlability of solar wind with seismic events in the Balkan peninsula zone [PDF]
Geološki Anali Balkanskoga Poluostrva, 2021 The Solar Heliospheric Observatory (SOHO) satellite was launched on the 2nd of December 1995 at L1 Lagrange point (1.5.106 km from Earth) with the purpose of gathering data for helioseismology, remote sensing of the solar atmosphere, and solar wind in ...

Helioseismology with PICARD [PDF]
Journal of Physics: Conference Series, 2013 PICARD is a CNES micro-satellite launched in June 2010 (Thuillier at al. 2006). Its main goal is to measure the solar shape, total and spectral irradiance during the ascending phase of the activity cycle. The SODISM telescope onboard PICARD also allows us to conduct a program for helioseismology in intensity at 535.7 nm (Corbard et al. 2008).
