High Resolution Helioseismic Imaging of Subsurface Structures and Flows of A Solar Active Region Observed by Hinode
Junwei Zhao, Alexander G. Kosovichev, Takashi Sekii
We analyze a solar active region observed by the Hinode CaII H line using the time-distance helioseismology technique, and infer wave-speed perturbation structures and flow fields…

Helioseismic Signature of Chromospheric Downflows in Acoustic Travel-Time Measurements from Hinode
Kaori Nagashima, Takashi Sekii, Alexander G. Kosovichev +2
We report on a signature of chromospheric downflows in two emerging-flux regions detected by time-distance helioseismology analysis. We use both chromospheric intensity oscillation…
