Hinode Observations of Magnetic Elements in Internetwork Areas
A. G. de Wijn, B. W. Lites, T. E. Berger +3
We use sequences of images and magnetograms from Hinode to study magnetic elements in internetwork parts of the quiet solar photosphere. Visual inspection shows the existence of ma…
Can We Improve the Preprocessing of Photospheric Vector Magnetograms by the Inclusion of Chromospheric Observations?
T. Wiegelmann, J. K. Thalmann, C. J. Schrijver +2
The solar magnetic field is key to understanding the physical processes in the solar atmosphere. Nonlinear force-free codes have been shown to be useful in extrapolating the corona…
First Stereoscopic Coronal Loop Reconstructions from Stereo Secchi Images
L. Feng, B. Inhester, S. K. Solanki +4
We present the first reconstruction of the three-dimensional shape of magnetic loops in an active region from two different vantage points based on simultaneously recorded images.…
Measuring a Kaluza-Klein radius smaller than the Planck length
Frank Reifler, Randall Morris
Hestenes has shown that a bispinor field on a Minkowski space-time is equivalent to an orthonormal tetrad of one-forms together with a complex scalar field. More recently, the Dira…
The Space Infrared Interferometric Telescope (SPIRIT): High-resolution imaging and spectroscopy in the far-infrared
David Leisawitz, Charles Baker, Amy Barger +53
We report results of a recently-completed pre-Formulation Phase study of SPIRIT, a candidate NASA Origins Probe mission. SPIRIT is a spatial and spectral interferometer with an ope…
Dynamic fibrils in H-alpha and C IV
A. G. de Wijn, B. De Pontieu
Aim: To study the interaction of the solar chromosphere with the transition region, in particular active-region jets in the transition region and their relation to chromospheric fi…
