Una descripción magnetohidrodinámica de la expansión de la corona solar
(Facultad de Ciencias Exactas y Naturales. Universidad de Buenos Aires, 1992)
Comparative Study of the Three-Dimensional Thermodynamical Structure of the Inner Corona of Solar Minimum Carrington Rotations 1915 and 2081
(Springer, 2017-10)
Using differential emission measure tomography (DEMT) based on time series of EUV images, we carry out a quantitative comparative analysis of the three-dimensional (3D) structure of the electron density and temperature of ...

Seeing The Solar Corona in Three Dimensions
(Elsevier, 2016-03)
The large availability and rich spectral coverage of today’s observational data of the solar corona, and the high spatial and temporal resolution provided by many instruments, has enabled the evolution of three-dimensional ...
Coronal Transient Events During Two Solar Minima: Their Solar Source Regions and Interplanetary Counterparts
(Springer, 2011-12)
In the frame of two coordinated observational and research efforts, two full solar rotations were investigated in the times of two distinct solar minima. These two campaigns were dubbed Whole Sun Month (WSM; 10 August – 8 ...
Serendipitous observation of a coronal mass ejection during the total solar eclipse of 14 December 2020
(S. A. Cannas, 2021-08-05)
We report observations of the total solar eclipse of 14 December 2020, during which a coronal mass ejection was seen to propagate. A comprehensive set of photographs covering a high dynamic range of exposure enabled ...
Plasma structure extraction from lasco images by the dual-tree complex wavelet transform
(2015-01-01)
Images of the Sun obtained in distinct electromagnetic ranges can be very useful to investigate electrodynamical processes that occur in this star. This work analyzes the application of a two-dimensional version of the ...
Three-Dimensional Electron Density from Tomographic Analysis of LASCO-C2 Images of the K-Corona Total Brightness
(Springer, 2010-05)
We present the first quantitative three-dimensional (3D) tomographic reconstructions of electron density from coronagraph measurements of the K-corona’s total brightness (B) made by LASCO-C2 on SOHO. This is possible ...
