Solar Neutrino Emission Deduced from a Seismic Model
Three helioseismic instruments on the Solar and Heliospheric Observatory have observed the Sun almost continuously since early 1996. This has led to detailed...
Solar oscillations as seen in the NaI and KI absorption lines
Data on the solar p modes observed simultaneously in the solar NaI and KI absorption lines were obtained in 1985 by operating two independent resonant...
Solar oscillations: time analysis of the GOLF p-mode signal
We determine the intrinsic phase lag of the GOLF data for the solar p-mode velocity deduced either from one of the narrow band photometers working alternatively...
The Iris network for helioseismology has operated since 1989. We present tables of solar p-mode frequencies for observations taken during the four summer...
Solar Particle Acceleration Radiation and Kinetics (SPARK). A mission to understand the nature of particle acceleration
Energetic particles are critical components of plasma populations found throughout the universe. In many cases particles are accelerated to relativistic...
Solar polarimetry in the K I D2 line : A novel possibility for a stratospheric balloon
Of the two solar lines, K I D1 and D2, almost all attention so far has been devoted to the D1 line, as D2 is severely affected by an O2 atmospheric band. This...
We characterize the K I D1 & D2 lines in order to determine whether they could complement the 850 nm window, containing the Ca II infrared triplet lines and...
Solar Prominences Embedded in Flux Ropes: Morphological Features and Dynamics from 3D MHD Simulations
The temporal evolution of a solar prominence inserted in a three-dimensional magnetic flux rope is investigated numerically. Using the model of Titov & Démoulin...
Solar Radial Velocity and Oscillations as Measured by Sodium and Potassium Resonant Scattering Spectrometers
Since the beginning of 1990, a sodium based resonance scattering spectrometer belonging to the IRIS Network has operated at Observatorio del Teide side by side...
