Large-scale horizontal flows in the solar photosphere. IV. On the vertical structure of large-scale horizontal flows
Michal Svanda, Mirek Klvana, Michal Sobotka +2
In the recent papers, we introduced a method utilised to measure the flow field. The method is based on the tracking of supergranular structures. We did not precisely know, whether…
Theoretical modeling of propagation of magneto-acoustic waves in magnetic regions below sunspots
E. Khomenko, A. Kosovichev, M. Collados +2
We use 2D numerical simulations and eikonal approximation, to study properties of MHD waves traveling below the solar surface through the magnetic structure of sunspots. We conside…
Prediction of Sunspot Cycles by Data Assimilation Method
I. N. Kitiashvili, A. G. Kosovichev
Despite the known general properties of the solar cycles, a reliable forecast of the 11-year sunspot number variations is still a problem. The difficulties are caused by the appare…
Nonlinear Solar Dynamo Model with Magnetic Helicity
I. N. Kitiashvili, A. G. Kosovichev
Variations of the sunspot number are important indicators of the solar activity cycles. The sunspot formation is a result of a dynamo process inside the Sun, which is far from bein…
POLAR Investigation of the Sun - POLARIS
T. Appourchaux, P. Liewer, M. Watt +34
The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft in a 0.48 AU circular orbit around the S…
Numerical simulation of excitation and propagation of helioseismic MHD waves: Effects of inclined magnetic field
K. V. Parchevsky, A. G. Kosovichev
Investigation of propagation, conversion, and scattering of MHD waves in the Sun is very important for understanding the mechanisms of observed oscillations and waves in sunspots a…
