Two-dimensional segmentation of small convective patterns in radiation hydrodynamics simulations
B. Lemmerer, D. Utz, A. Hanslmeier +4
Recent results from high-resolution solar granulation observations indicate the existence of a population of small granular cells that are smaller than 600 km in diameter. These sm…
Nonlinear Force-Free Field Modeling of the Solar Magnetic Carpet and Comparison with SDO/HMI and Sunrise/IMaX Observations
L. P. Chitta, R. Kariyappa, A. A. van Ballegooijen +2
In the quiet solar photosphere, the mixed polarity fields form a magnetic carpet, which continuously evolves due to dynamical interaction between the convective motions and magneti…
Observations and modeling of the emerging EUV loops in the quiet Sun as seen with the Solar Dynamics Observatory
LP. Chitta, R. Kariyappa, A. A. van Ballegooijen +3
We used data from the Helioseismic and Magnetic Imager (HMI), and Atmospheric Imaging Assembly (AIA) on the \textit{Solar Dynamics Observatory} (SDO) to study coronal loops at smal…
Dynamics of the solar magnetic bright points derived from their horizontal motions
LP. Chitta, A. A. van Ballegooijen, L. Rouppe van der Voort +2
The sub-arcsec bright points (BP) associated with the small scale magnetic fields in the lower solar atmosphere are advected by the evolution of the photospheric granules. We measu…
Detection of mesogranulation at the upper chromosphere from SOHO/SUMER observations
R. Kariyappa, B. A. Varghese, W. Curdt
We have analyzed a time series of spectra in the hydrogen Lyman lines and the Lyman continuum obtained by the Solar Ultraviolet Measurements of Emitted Radiation (SUMER) spectromet…
Solar coronal differential rotation from XBPs in Hinode/XRT and Yohkoh/SXT images
R. Kariyappa
Our aim is to identify and trace the X-ray Bright Points (XBPs) over the disk and use them as tracers to determine the coronal rotation. This investigation will help to clarify and…
