Helioseismic dating

is the study of the propagation of pressure waves in the Sun. Unlike seismic waves on earth, solar waves have practically no shear component (s waves). Solar pressure waves are generated by the turbulence in the convection zone, near the surface… Helioseismic dating 15 May. REFERENCES: A Ph D student is designing and building a solar adaptive optics studying solar features, including filaments. We are also involved in the design of ground based high cadence imaging projects and solar radio telescope projects. All dating methods have the same problem. They all depend on assumptions and the assumptions are always made such that the answer is acceptable to preexisting beliefs—the paradigm. Your Helioseismic dating claim is not evidence but just an interpretation to fit within the long-age view. Helioseismic Network Provides Valuable Data. ... renormalisation of activity to a distant reference date, application of nuclear dating for archaeology, geo- and cosmochronology, nor in ...

The consensus view of scientists in relevant fields is that the age of the Earth and the solar system is roughly 4.54 billion (4.54 × 10 9 ± 1%) years, an age primarily derived by radiometric dating.Because of the molten state of the early Earth, erosion, and subduction of tectonic plates moving surface material into the Earth's mantle, radiometric dating of materials originating on Earth ... Helioseismic dating works by measuring the attenuation of vibrations in the sun, and magnetostratigraphy works by measuring the residual magnetism of rocks. The upshot is that we've shown you the non-radiometric methods that confirm the radiometric methods, and hence the accepted geochronology of the earth. Helioseismic dating. The age of the sun can be inferred with helioseismic studies. [16] This is because the propagation of acoustic waves deep within the sun depends on the composition of the sun, in particular the relative abundance of helium and hydrogen in the core.

PhD computational helioseismology: requires math, physics and programming background

2017.08.09 15:48 solarsystemschool PhD computational helioseismology: requires math, physics and programming background

The launch in 2010 of the Solar Dynamics Observatory (SDO) spacecraft was an important technological step for helioseismology. With a high spatial resolution over the entire visible solar hemisphere, SDO enables us to follow the evolution of solar active regions as they rotate across the solar disk. ESA’s Solar Orbiter will, for the first time, give access to the subsurface dynamics of the Sun’s polar regions.
In order to cope with the huge SDO data flow of the order of 1 TB/day, significant computing and storage resources were deployed at the MPS to set up a German Science Center for SDO (GDC-SDO). This major facility is operational today. Discoveries have been made concerning the subsurface structure of sunspots and the dynamics in the upper convection zone. Further advances will rely on new techniques of computational helioseismology, inspired from terrestrial seismology.
The quantitative interpretation of helioseismic observations from the SDO satellite requires numerical simulations of wave propagation in the solar interior, high-performance computing, and modern inverse methods. The MPI for Solar System Research is investing in a major effort to push the frontiers of computational helioseismology. We are looking for PhD students with an interest in numerical modeling and applied mathematics ... Learn more ...
