Journal ArticleDOI
HMI ring diagram analysis I. The processing pipeline
TL;DR: In this paper, a ring-diagrams pipeline is proposed to map the evolution of the circulation and local subsurface flows on a global scale from the surface to depths of down to 0.9Rsun.
Journal ArticleDOI
Meridional Flows from Ring Diagram Analysis
TL;DR: In this paper, the authors applied ring diagram analysis to a set of small regions over the surface to search for meridional circulation in the solar envelope, and found poleward flows between r/R=0.97 and the surface.
Journal ArticleDOI
Chromospheric and coronal observations of solar flares with the helioseismic and magnetic imager
Juan-Carlos Martínez Oliveros,Säm Krucker,Hugh S. Hudson,Hugh S. Hudson,Pascal Saint-Hilaire,Hazel Bain,Charles Lindsey,R. S. Bogart,Sebastien Couvidat,P. H. Scherrer,Jesper Schou +10 more
TL;DR: In this article, the authors report observations of white-light ejecta in the low corona, for two X-class flares on 2013 May 13, using data from the Helioseismic and Magnetic Imager (HMI) of the Solar Dynamics Observatory.
Journal ArticleDOI
HMI ring diagram analysis II. Data products
TL;DR: In this paper, a ring-diagram analysis of solar subsurface flows and thermal structure variations using the technique of ring diagram analysis on an unprecedented scale is described, and the synoptic pipeline execution is discussed.
Journal ArticleDOI
Subsurface Meridional Flow from HMI Using the Ring-Diagram Pipeline
R. W. Komm,I. González Hernández,Frank Hill,R. S. Bogart,M. C. Rabello-Soares,Deborah A. Haber +5 more
TL;DR: In this paper, the meridional flows in subsurface layers for 18 Carrington rotations were determined using high-resolution Dopplergrams obtained with the Helioseismic and Magnetic Imager (HMI) instrument onboard the Solar Dynamics Observatory (SDO).
