Solving the discrepancy between the seismic and photospheric solar radius
Margit Haberreiter, Alexander G. Kosovichev, Werner Schmutz
Two methods are used to observationally determine the solar radius: One is the observation of the intensity profile at the limb, the other one uses f-mode frequencies to derive a '…
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…
Numerical simulation of excitation of solar oscillation modes for different turbulent models
L. Jacoutot, A. G. Kosovichev, A. Wray +1
The goal of this research is to investigate how well various turbulence models can describe physical properties of the upper convective boundary layer of the Sun. An accurate model…
Speed of Meridional Flows and Magnetic Flux Transport on the Sun
M. Svanda, A. G. Kosovichev, J. Zhao
We use the magnetic butterfly diagram to determine the speed of the magnetic flux transport on the solar surface towards the poles. The manifestation of the flux transport is clear…
The Cause of Photospheric and Helioseismic Responses to Solar Flares: High-Energy Electrons or Protons?
A. G. Kosovichev
Analysis of the hydrodynamic and helioseismic effects in the photosphere during the solar flare of July 23, 2002, observed by Michelson Doppler Imager (MDI) on SOHO, and high-energ…
Initial Helioseismic Observations by Hinode/SOT
Takashi Sekii, Alexander G. Kosovichev, Junwei Zhao +12
Results from initial helioseismic observations by Solar Optical Telescope onboard Hinode are reported. It has been demonstrated that intensity oscillation data from Broadband Filte…
