Mechanism of mean flow generation in rotating turbulence and its relation to inertial wave

Author: Kazuhiro INAGAKI
Recent numerical simulation revealed that large-scale flow is generated in a rotating system with inhomogeneous helicity. However its mechanism was not examined in terms of the Reynolds stress transport. In this study, the large-e ... more

Solar flare/CME initiation and signatures with EST

Author: Kévin Dalmasse
Solar flares and eruptive events are driven by the 3D evolution of current-carrying magnetic fields in the solar atmosphere. While several mechanisms have been identified, we still do not know which ones are really responsible for ... more

Observation on Current Helicity and Proxies of Subsurface Kinetic Helicity in Solar Active Regions

Author: Yu Gao
By using the photospheric vector magnetogram and subsurface vector velocity field, we studied the systematic behavior of current helicity and relevant quantities of subsurface flow. Mainly it contains three aspects: 1) The spatial ... more

An estimate of chromospheric heating by acoustic waves - reloaded

Author: Michal Sobotka
Several mechanisms may heat the solar chromosphere: acoustic waves, magnetoacoustic waves (slow, fast, and Alfven waves), and small-scale magnetic reconnections. Based on observations in the Ca II 854.2 nm line, the contribution o ... more

Differential Rotation and Dynamo Action in Solar-like Stars

Author: Jacobo Varela
The aim of the present study is to characterize the effect of the rotation rate in building magnetic field via dynamo action in solar-like stars. We use the code ASH to model the convective dynamo for solar-like stars at vario ... more

GONG Status

Author: Frank Hill
GONG (Global Oscillation Network Group) is now 20 years old and continues to reliably provide data for the international helioseismology community. In addition the role of GONG has expanded to provide data as input to a number of ... more

Observations of the uncoupling of ionized and neutral species in solar prominences

Author: Manuel Collados
The aim of this work is to measure possible differences in the dynamics of the ionized and neutral components of the solar plasma, as a manifestation of partial ionization effects due to an incomplete collisional coupling, causing ... more

How much can the damping of the observed power spectrum of transverse waves contribute to coronal heating?

Author: Paolo Pagano
Observations of coronal loops have long revealed ubiquitous, transverse velocity perturbations, that undergo strong damping as they propagate. Observational estimates show that these perturbations contain significant amounts of en ... more

A statistical study of CME properties and of the correlation between flares and CMEs over solar cycles 23 and 24

Author: compagnino antonio alessio
The Large Angle Spectrometric Coronagraph (LASCO), onboard the Solar and Heliospheric Observatory (SOHO) provided us observations extending for the two Solar Cycles 23 and 24 (31 July 1996 - 31 March 2014) that allow one to compar ... more
