Journal ArticleDOI
Solar neutrinos, helioseismology and the solar internal dynamics
TL;DR: A review of the solar neutrino puzzle can be found in this paper, where the authors highlight the importance of the Superkamiokande and SNO detectors to demonstrate that the solar-emitted electronic neutrinos are partially transformed into other neutrini flavors before reaching the Earth.
Journal ArticleDOI
Line-of-Sight Observables Algorithms for the Helioseismic and Magnetic Imager (HMI) Instrument Tested with Interferometric Bidimensional Spectrometer (IBIS) Observations
Sebastien Couvidat,S. P. Rajaguru,Richard Wachter,K. Sankarasubramanian,K. Sankarasubramanian,Jesper Schou,Philip H. Scherrer +6 more
TL;DR: In this paper, the authors used one hour of high-cadence imaging spectropolarimetric observations of a sunspot in the Fe-i line at 6173 A through the Interferometric Bidimensional Spectrometer installed at the Dunn Solar Telescope, and the Milne-Eddington inversion of the corresponding Stokes vectors.
Journal ArticleDOI
Wavelength Dependence of the Helioseismic and Magnetic Imager (HMI) Instrument onboard the Solar Dynamics Observatory (SDO)
Sebastien Couvidat,Jesper Schou,Richard A. Shine,R. I. Bush,J. W. Miles,Philip H. Scherrer,Richard L. Rairden +6 more
TL;DR: In this paper, the authors present a series of wavelength-dependent calibration tests performed on the HMI optical-filter system from 2005 to 2012 to obtain the transmittances as a function of wavelength for the tunable and non-tunable filter elements.
Journal ArticleDOI
On the Characteristics of the Solar Gravity Mode Frequencies
TL;DR: In this article, specific physical processes influence the theoretical g-mode frequencies for the l = 1 and l = 2 modes over a large range of radial orders n from -46 to -1, corresponding to potential SOHO observations.
On the Formation Height of the SDO/HMI Fe 6173 A
TL;DR: In this article, the authors used the output of a high-resolution 3D, time-dependent, radiation-hydrodynamic simulation based on the CO 5 BOLD code to calculate velocities for the Fe i 6173 A line.
