Journal Article
Roediger, E., Kraft, R. P., Nulsen, P., Churazov, E., Forman, W., Brüggen, M., & Kokotanekova, R. (2013). Viscous Kelvin-Helmholtz instabilities in highly ionised plasmas. Monthly notices of the Royal Astronomical Society, 436(2), 1721-1740. https://doi.org/10.1093/mnras/stt1691

Transport coefficients in highly ionised plasmas like the intra-cluster medium (ICM) are still ill-constrained. They influence various processes, among them the mixing at shear flow interfaces due to the Kelvin-Helmholtz instability (KHI). The observ...

The R Coronae Borealis (RCB) stars are hydrogen-deficient, variable stars that are most likely the result of He-CO WD mergers. They display extremely low oxygen isotopic ratios, 16 O/ 18 O ≃ 1-10, 12 C/ 13 C ≥ 100, and enhancements up to 2.6 dex in...

Can we detect local helioseismic parameter shifts in coronal holes? (2013)
Presentation / Conference Contribution
Howe, R., Haber, D. A., Bogart, R. S., Zharkov, S., Baker, D., Harra, L., & Driel-Gesztelyi, L. V. Can we detect local helioseismic parameter shifts in coronal holes?

Changes in helioseismic mode parameters in active regions and across the solar disk are well documented, but local magnetic activity and geometric effects may not account for all of the scatter seen in the results. We use results from theHelioseismic... Read More about Can we detect local helioseismic parameter shifts in coronal holes?.

The crystal structure of the melamine:cyanuric acid (CA.M) adduct has been redetermined and the previously reported cell is shown to be incorrect. The true unit cell has approximately twice the volume of the earlier cell. Crystal data forCA.M: monocl... Read More about The structure of the melamine–cyanuric acid co-crystal.
