MHD simulation of magnetic field configuration above the active region NOAA 10365
Podgorny, I. M.; Podgorny, A. I.
The current sheet (CS) creation before a flare in the vicinity of a singular line above the active region NOAA 10365 is shown in numerical experiments. Such a way the possibility of energy accumulation for a solar flare is demonstrated. These data and results of observation confirm the electrodynamical solar flare model that explains solar flares …

Cosmic Star Formation History and AGN Evolution Near and Far: AKARI Reveals both
Goto, Tomotsugu; AKARI NEP Team; AKARI All Sky Survey Team
Understanding infrared (IR) luminosity is fundamental to understanding the cosmic star formation history and AGN evolution, since their most intense stages are often obscured by dust. Japanese infrared satellite, AKARI, provided unique data sets to probe this both at low and high redshifts. The AKARI performed all sky survey in 6 IR bands (9, 18, …

Outflow Velocity Structure in the Upper Transition Region and Corona
Abbo, Lucia; Gabriel, Alan
Outflow velocity maps in the quiet Sun and coronal hole regions have been observed with the EUV Imaging Spectrometer on Hinode over a range of coronal and transition region temperatures, in order to correlate the solar wind with effects due to the underlying supergranule network and to coronal holes. The cell structure has been identified using da…
Lyman α Emission and Super-Star Clusters in Dwarf Galaxies
Östlin, Göran
Lyman α (Lyα) is the intrinsically most powerful spectral probe of ongoing star formation, and the only one easily accessible at redshifts z > 2.5. For low mass galactic building blocks which have low luminosities from hot dust, Lyα is currently the only probe available. However, its large absorption cross section in neutral hydrogen leads to s…
Young stars in gas-dust disks. II. Vega (α Lyr) and β Pic
Arkharov, A. A.; Ruban, E. V.
Observational data for Vega, α Lyr in the 325-1080 nm range from various years are studied using material stored at the Pulkovo Spectrophotometric Data Base (PSDB). It is shown that the spectrophotometric temperature of the star was lower than the effective temperature according to data from all the observational seasons. Possible reasons for this…
