Helioseismic evidence of two solar granulation timescales
The signature of two different scales of solar granulation in the power spectrum of disk integrated irradiance time series is presented. The fitted timescales...
Helioseismic holography of simulated sunspots: dependence of the travel time on magnetic field strength and Wilson depression
Improving methods for determining the subsurface structure of sunspots from their seismic signature requires a better understanding of the interaction of waves...
Helioseismic Holography of Simulated Sunspots: Magnetic and Thermal Contributions to Travel Times
Wave propagation through sunspots involves conversion between waves of acoustic and magnetic character. In addition, the thermal structure of sunspots is very...
The PICARD mission is a CNES micro-satellite to be launched in 2009. Its goal is to better understand the Sun and the potential impact of its activity on earth...
Heliosismología: la visión pitagórica de la astrofísica.
Durante los últimos 45 años, el grupo de Sismología Solar (y Estelar y Búsqueda de Exoplanetas) del Instituto de Astrofísica de Canarias, ha estado observando...
An international team of astronomers, in which the researcher from the Instituto de Astrofísica de Canarias and the Universidad de La Laguna David Jones...
Improved detection of far-side solar active regions using deep learning
Context. The analysis of waves on the visible side of the Sun allows the detection of active regions on the far side through local helioseismology techniques...
Influence of Low-Degree High-Order p-Mode Splittings on the Solar Rotation Profile
The solar rotation profile is well constrained down to about 0.25 R &sun; thanks to the study of acoustic modes. Since the radius of the inner turning point of...
