A brief history of the solar diameter measurements: a critical quality assessment of the existing data
Jean Pierre Rozelot, Alexander G. Kosovichev, Ali Kilcik
The size of the diameter of the Sun has been debated for a very long time. First tackled by the Greek astronomers from a geometric point of view, an estimate, although incorrect, h…
Reconstruction of Solar Subsurfaces by Local Helioseismology
Alexander G. Kosovichev, Junwei Zhao
Local helioseismology has opened new frontiers in our quest for understanding of the internal dynamics and dynamo on the Sun. Local helioseismology reconstructs subsurface structur…
Local Helioseismology of Emerging Active Regions: A Case Study
Alexander G. Kosovichev, Junwei Zhao, Stathis Ilonidis
Local helioseismology provides a unique opportunity to investigate the subsurface structure and dynamics of active regions and their effect on the large-scale flows and global circ…
2-D and 3-D Models of Convective Turbulence and Oscillations in Intermediate-Mass Main-Sequence Stars
Joyce A. Guzik, T. H. Morgan, N. J. Nelson +5
We present multidimensional modeling of convection and oscillations in main-sequence stars somewhat more massive than the Sun, using three separate approaches: 1) Using the 3-D pla…
Observational Investigation of Energy Release in the Lower Solar Atmosphere of a Solar Flare
I. N. Sharykin, V. M. Sadykov, A. G. Kosovichev +2
We study flare processes in the lower solar atmosphere using observational data for a M1-class flare of June 12, 2014, obtained by New Solar Telescope (NST/BBSO) and Helioseismic M…
Relationship between chromospheric evaporation and magnetic field topology in M-class solar flare
V. M. Sadykov, A. G. Kosovichev, I. N. Sharykin +2
Chromospheric evaporation is observed as Doppler blueshift during solar flares. It plays one of key roles in dynamics and energetics of solar flares, however, its mechanism is stil…
