Helium Emissions as a Probe for Plasma Temperatures.
The strongest He II emission in the visible spectral range, at 4686 A, is for the first time observed at a spectral resolution sufficiently high for a line...
Morphological And Thermal Properties Of The Solar Corona : Diagnostic Tools & Applications
Progress in our understanding of the Solar corona and its underlying heating and acceleration processes, depends critically on our ability to measure...
A 2D Model for Coronal Bright Points: Association with Spicules, UV Bursts, Surges, and EUV Coronal Jets
Coronal bright points (CBPs) are ubiquitous structures in the solar atmosphere composed of hot small-scale loops observed in extreme-ultraviolet (EUV) or X-rays...
A summary of solar 1-8A measurements from the SMS and GOES satellites, 1977-1981
The 1-8A band of synodic full-disc solar X-rays (1-8A) W/m(2) were measured nearly continuously from 1975 to 1981 aboard the SMS-1, SMS-2, GOES-1, GOES-2, and...
Accelerating Non-LTE Synthesis and Inversions with Graph Networks
The computational cost of fast non-LTE synthesis is one of the challenges that limits the development of 2D and 3D inversion codes. It also makes the...
An example of the cancellation of magnetic fields during the decay of an active region
A case of cancellation of magnetic fields is observed during the decay of a small active region. Three different sources of information were simultaneously used...
Deciphering Solar Coronal Heating: Energizing Small-scale Loops through Surface Convection
The solar atmosphere is filled with clusters of hot small-scale loops commonly known as coronal bright points (CBPs). These ubiquitous structures stand out in...
Desarrollan un novedoso código para investigar el magnetismo de la corona solar
El grupo de investigación POLMAG del Instituto de Astrofísica de Canarias (IAC) acaba de hacer público P-CORONA, un código para calcular la intensidad y...
El experimento espacial CLASP2 cartografía, por primera vez, el campo magnético solar desde la fotosfera hasta la base de la corona
Los telescopios espaciales obtienen cada día imágenes espectaculares de la actividad solar. Sin embargo, sus instrumentos son ciegos al responsable de tal...
