Stray Light Correction for the Helioseismic and Magnetic Imager
A. A. Norton, T. L. Duvall, J. Schou +6
We report a point spread function (PSF) and deconvolution procedure to remove stray light from the Helioseismic and Magnetic Imager (HMI) data. Pre-launch calibration observations,…
Photometry and spectroscopy of massive stars observed during K2 Campaign 8
Jéssica M. Eidam, Laerte Andrade, Marcelo Emilio +4
We report in this paper spectroscopic and photometric analysis of eight massive stars observed during Campaign 8 of the Kepler/K2 mission from January to March 2016. Spectroscopic…
Statistical analysis of acoustic wave power and flows around solar active regions
M. Cristina Rabello-Soares, Richard S. Bogart, Philip H. Scherrer
We analyze the effect of a sunspot in its quiet surroundings applying a helioseismic technique on almost three years of Helioseismic and Magnetic Imager (HMI) observations obtained…
Statistical analysis of acoustic wave parameters near active regions
M. Cristina Rabello Soares, Richard S. Bogart, Philip H. Scherrer
In order to quantify the influence of magnetic fields on acoustic mode parameters and flows in and around active regions, we analyse the differences in the parameters in magnetical…
Recent results in Ring Diagram analysis
M. Cristina Rabello-Soares
The ring-diagram technique was developed by Frank Hill 25 years ago and developed quickly during the late 1990s. It is nowadays one of the most commonly used techniques in local he…
Temporal Variations of High-Degree Solar p-Modes using Ring-Diagram Analysis
Olga Burtseva, Sushant Tripathy, Richard Bogart +4
We study temporal variations in the amplitudes and widths of high-degree acoustic modes by applying the ring-diagram technique to the GONG+, MDI and HMI Dopplergrams during the dec…
