ASTRONOMY AND ASTROPHYSICS Torsional oscillations in the solar convection zone
Recent analysis of the helioseismic observations indicate that the previously observed surface torsional oscillations extend significantly downwards into the solar convection zone. In an attempt to understand these oscillations, we study the nonlinear coupling between the magnetic field and the solar differential rotation in the context of a mean field dynamo model, in which the nonlinearity is...
متن کاملNon - Linear Data Analysis in Solar Radio Astronomy
We have discussed some tools from nonlinear dynamics which may help to analyze transient phenomena, such as solar bursts. The structure function known from turbulence theory is an appropriate method to nd out some scaling behavior of uctuations in time. More generally, the wavelet analysis, which is some generalization of the power spectrum, exhibits information on the location as well as the s...
متن کاملAstronomy and Astrophysics Opacity Effects on the Solar Interior I. Solar Structure
Despite recent major advances, the opacity remains a source of substantial uncertainty in the calculation of solar models, and hence of solar oscillation frequencies. Hence it is of substantial interest to investigate the sensitivity of solar structure to changes in the opacity. Furthermore, we may hope from the precise helioseismic inferences of solar structure to obtain information about poss...
متن کاملAstronomy and Astrophysics the Protostellar System Hh108mms
We probe the region around the protostar HH108MMS by deep mid infrared photometric and po-larimetric imaging. The protostar is detected at 14µm in absorption against the diffuse background. Next to HH108MMS, we find a second absorbing core, named Q1, and the young stellar object IRAS18331–0035 which is more advanced in its evolution and already seen in emission at 12µm and 14µm. HH108MMS, Q1 an...
متن کاملSolar System
Planetary Science is the branch of knowledge benefiting most as a result of the space age. In less than half a century, the field has been revolutionized by the influx of new images, observations, and other forms of data. Most planets and their larger satellites have been transformed from telescopic objects to individual worlds. Each has revealed a distinctive geological pedigree. New twists on...
