Multi-pronged investigations into exoplanetary magnetic fields
Wilson Cauley (Arizona State University)
Efforts in exoplanet characterization have led to some very precise determinations of planetary densities, compositions, and even accurate maps of active region and spot locations on stellar surfaces. Exoplanet magnetic fields, however, remain elusive. While radio observations continue to push into the low-mass brown dwarf regime, no emission from a planetary-mass object has been confirmed. I will discuss some of the efforts involving alternate methods for probing exoplanet magnetic fields and how they stack up so far against the prospects for detection via radio emission.
SHINE: code for everything
Tim Fitzpatrick, Artist, Scotland
SHINE, ’Code for Everything’ is an on-going art work by Tim Fitzpatrick in collaboration with astronomer Anne-Marie Weijmans of the School of Physics and Astronomy at the University of St Andrews. The art takes its inspiration from the Anne-Marie’s work and the science of spectroscopy and, in particular, through a series of visual and experimental representations of the individual emission spectra of the elements.
Tim Fitzpatrick’s principal development of the work is through his fascination with the extraordinary level of detail – and therefore information – contained in the spectrum of starlight. As the work progresses and evolves he seeks to develop the theme of the linguistics of the light of the elements and, by extension, our reading of the light of the universe and our place in it, as described in a series of codes.
