Numerical MHD Simulations of Solar Magnetoconvection and Oscillations in Inclined Magnetic Field Regions
I. N. Kitiashvili, A. G. Kosovichev, N. N. Mansour +1
The sunspot penumbra is a transition zone between the strong vertical magnetic field area (sunspot umbra) and the quiet Sun. The penumbra has a fine filamentary structure that is c…
Excitation of acoustic waves by vortices in the quiet Sun
I. N. Kitiashvili, A. G. Kosovichev, N. N. Mansour +1
Five-minutes oscillations is one of the basic properties of solar convection. Observations show mixture of a large number of acoustic wave fronts propagating from their sources. We…
A precise asteroseismic age and radius for the evolved Sun-like star KIC 11026764
T. S. Metcalfe, M. J. P. F. G. Monteiro, M. J. Thompson +55
The primary science goal of the Kepler Mission is to provide a census of exoplanets in the solar neighborhood, including the identification and characterization of habitable Earth-…
Mechanism of spontaneous formation of stable magnetic structures on the Sun
I. N. Kitiashvili, A. G. Kosovichev, A. A. Wray +1
One of the puzzling features of solar magnetism is formation of long-living compact magnetic structures; such as sunspots and pores, in the highly turbulent upper layer of the sola…
Explanation of the sea-serpent magnetic structure of sunspot penumbrae
I. N. Kitiashvili, L. R. Bellot Rubio, A. G. Kosovichev +3
Recent spectro-polarimetric observations of a sunspot showed the formation of bipolar magnetic patches in the mid penumbra and their propagation toward the outer penumbral boundary…
The asteroseismic potential of Kepler: first results for solar-type stars
W. J. Chaplin, T. Appourchaux, Y. Elsworth +105
We present preliminary asteroseismic results from Kepler on three G-type stars. The observations, made at one-minute cadence during the first 33.5d of science operations, reveal hi…
