Spherical Born Kernels for Flows in Time-Distance Helioseismology
Author: Vincent BöningWe extend an existing Born approximation model for calculating the linear sensitivity of helioseismic travel-times to flows from Cartesian to spherical geometry. This development is necessary to use the Born approximation for in ... more Views: 540
Exploitation of Space Data for Innovative Helio- and Asteroseismology - SpaceInn
Author: Markus RothThe European Helio- and Asteroseismology Network (HELAS) has initiated the follow-up project "SpaceInn - Exploitation of Space Data for Innovative Helio- and Asteroseismolgoy" with the mission to build on the existing European str ... more Views: 667
Statistical investigation of CMEs properties and their correlation with flares during Solar Cycle 23 and 24.
Author: compagnino antonio alessioThe 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 Views: 75
Validating Spherical Born Kernels for Meridional Flows
Author: Vincent BöningWe present the current status of an undergoing validation of a recently developed model for computing spherical Born approximation sensitivity functions for flows. In a first step, power spectra and reference cross-correlations fr ... more Views: 563
High-resolution modeling of the solar photosphere with the ANTARES RHD-code
Author: Peter LeitnerSmall granules that do not originate from the fragmentation process of regular sized granular cells and evolve on a considerably shorter timescale populate the intergranular lanes. They are found in high-resolution observational a ... more Views: 868
Interference of geomagnetic storms in ionospheric plasma bubbles over last solar minimum period
Author: Flavia Coelho TardelliStudies presented on the relation Sun-Earth system are of great importance currently. Ionospheric irregularities in the F-region, caused by geomagnetic storms have meanings and adverse effects on the Earth. The recent advancement ... more Views: 559
Solar Physics Research Integrated Network Group (SPRING) : A Next Generation Ground-based Synoptic Network
Author: Sanjay gosainSPRING is an evolving concept for next generation solar synoptic observations network. It is envisaged that the new network will cater to the needs of (i) Helioseismology community, by providing improved resolution Doppler observa ... more Views: 615
Numerical simulations of magneto-acoustic wave propagation from the upper convection zone into the chromosphere.
Author: Christian NuttoThe contribution of acoustic waves to the chromospheric heating is still an open question. To discuss this Issue, it is crucial to understand the propagation of waves from the convection zone, where the waves are excited, into the ... more Views: 555
Temporal variations of Solar and Interplanetary conditions for the last 4 decades
Author: Bogyeong KimThere are many parameters representing the conditions of space environments. Those are modulated in general by Solar Cycle (SC) defined by sunspot number temporal variation. However, all parameters do not have same cyclic features ... more Views: 664
LARS – the Laser Absolute Reference Spectrograph at the VTT
Author: Johannes Löhner-BöttcherLARS is an Absolute Reference Spectrograph. It performs fiber-coupled solar observations with the high-resolution Echelle Spectrograph of the Vacuum Tower Telescope (VTT) at the Observatorio del Teide on Tenerife. The scientific i ... more Views: 716
