Diffusion of muonium and hydrogen in diamond
Carlos P. Herrero, Rafael Ramirez
Jump rates of muonium and hydrogen in diamond are calculated by quantum transition-state theory, based on the path-integral centroid formalism. This technique allows us to study th…
Discovery of a wide companion near the deuterium burning mass limit in the Upper Scorpius association
V. J. S. Bejar, M. R. Zapatero Osorio, A. Perez-Garrido +5
We present the discovery of a companion near the deuterium burning mass limit located at a very wide distance, at an angular separation of 4.6+/-0.1 arcsec (projected distance of ~…
A 3-D sunspot model derived from an inversion of spectropolarimetric observations and its implications for the penumbral heating
C. Beck
I deduced a 3-D sunspot model that is in agreement with spectropolarimetric observations, to address the question of penumbral heating by the repetitive rise of flow channels. I pe…
The Host Galaxies and Black Holes of Typical z~0.5-1.4 AGN
A. Alonso-Herrero, P. G. Perez-Gonzalez, G. H. Rieke +5
We study the stellar and star formation (SF) properties of the host galaxies of 58 X-ray selected AGN in the GOODS portion of the Chandra Deep Field South (CDF-S) region at z~0.5-1…
Spectropolarimetry of a decaying sunspot penumbra
L. R. Bellot Rubio, A. Tritschler, V. Martinez Pillet
We report on high angular resolution, high precision spectropolarimetric measurements of a decaying sunspot. The spot gradually lost its penumbra during the course of three days. I…
Magnetic field emergence in quiet Sun granules
D. Orozco Suarez, L. R. Bellot Rubio, J. C. del Toro Iniesta +1
We describe a new form of small-scale magnetic flux emergence in the quiet Sun. This process seems to take vertical magnetic fields from the solar interior to the photosphere, wher…
