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…
