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…
Kepler photometry of the prototypical Blazhko star RR Lyr: An old friend seen in a new light
K. Kolenberg, S. Bryson, R. Szabó +18
We present our analysis of the long cadence Kepler data for the well-studied Blazhko star RR Lyr, gathered during the first two quarters of the satellite's observations and coverin…
Modeling of the subgrid-scale term of the filtered magnetic field transport equation
G. Balarac, A. G. Kosovichev, O. Brugière +2
Accurate subgrid-scale turbulence models are needed to perform realistic numerical magnetohydrodynamic (MHD) simulations of the subsurface flows of the Sun. To perform large-eddy s…
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-…
NLTE model atmospheres for the hottest white dwarfs: Spectral analysis of the compact component in nova V4743 Sgr
T. Rauch, M. Orio, R. Gonzales-Riestra +4
Half a year after its outburst in September 2002, nova V4743 Sgr evolved into the brightest supersoft X-ray source in the sky with a flux maximum around 30A. We calculated grids of…
The disk-bearing young star IM Lup
H. M. Guenther, S. P. Matt, J. H. M. M. Schmitt +3
Classical T Tauri stars (CTTS) differ in their X-ray signatures from older pre-main sequence stars, e.g. weak-lined TTS (WTTS). CTTS show a soft excess and deviations from the low-…
