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…
AsteroFLAG: first results from hare-and-hounds Exercise 1
W. J. Chaplin, T. Appourchaux, T. Arentoft +15
We report on initial results from the first phase of Exercise 1 of the asteroFLAG hare and hounds. The asteroFLAG group is helping to prepare for the asteroseismology component of…
Properties of high-degree oscillation modes of the Sun observed with Hinode/SOT
U. Mitra-Kraev, A. G. Kosovichev, T. Sekii
Aims. With the Solar Optical Telescope on Hinode, we investigate the basic properties of high-degree solar oscillations observed at two levels in the solar atmosphere, in the G-ban…
Initial Observations of Sunspot Oscillations Excited by Solar Flare
A. G. Kosovichev, T. Sekii
Observations of a large solar flare of December 13, 2006, using Solar Optical Telescope (SOT) on Hinode spacecraft revealed high-frequency oscillations excited by the flare in the…
