The Helioseismic and Magnetic Imager (HMI) Vector Magnetic Field Pipeline: Magnetohydrodynamics Simulation Module for the Global Solar Corona
Keiji Hayashi, J. Todd Hoeksema, Yang Liu +3
Time-dependent three-dimensional magnetohydrodynamics (MHD) simulation modules are implemented at the Joint Science Operation Center (JSOC) of Solar Dynamics Observatory (SDO). The…
The Helioseismic and Magnetic Imager (HMI) Vector Magnetic Field Pipeline: SHARPs -- Space-weather HMI Active Region Patches
Monica G. Bobra, Xudong Sun, J. Todd Hoeksema +5
A new data product from the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) called Space-weather HMI Active Region Patches (SHARPs) is now avail…
The Helioseismic and Magnetic Imager (HMI) Vector Magnetic Field Pipeline: Optimization of the Spectral Line Inversion Code
R. Centeno, J. Schou, K. Hayashi +5
The Very Fast Inversion of the Stokes Vector (VFISV) is a Milne-Eddington spectral line inversion code used to determine the magnetic and thermodynamic parameters of the solar phot…
Reflection and refraction of (magneto-)acoustic waves at the magnetic canopy: further evidences from multi-height seismic data
S. P. Rajaguru, Xudong Sun, K. Hayashi +1
We recently presented evidences (Rajaguru et al. 2012) that seismic halos around expanding magnetic structures in the lower solar atmosphere are related to the acoustic to magnetoa…
Properties of high-frequency wave power halos around active regions: an analysis of multi-height data from HMI and AIA onboard SDO
S. P. Rajaguru, S. Couvidat, Xudong Sun +2
We study properties of waves of frequencies above the photospheric acoustic cut-off of 5.3 mHz, around four active regions, through spatial maps of their power estimated u…
Detection of the Horizontal Divergent Flow prior to the Solar Flux Emergence
S. Toriumi, K. Hayashi, T. Yokoyama
It is widely accepted that solar active regions including sunspots are formed by the emerging magnetic flux from the deep convection zone. In previous numerical simulations, we fou…
