Using the WASP transit survey, we report the discovery of three new hot Jupiters, WASP-68 b, WASP-73 b and WASP-88 b. The planet WASP-68 bhas a mass of 0.95 ± 0.03 MJup, a radius of 1.24-0.06+0.10 RJup, and orbits a V = 10.7 G0-type star (1.24 ± 0.0...

Tantalum and niobium diffusion in single crystalline lithium niobate (2014)
Journal Article
Fielitz, P., Borchardt, G., Ganschow, S., Bertram, R., Jackson, R., Fritze, H., & Becker, K. (2014). Tantalum and niobium diffusion in single crystalline lithium niobate. Solid State Ionics, 259, 14-20. https://doi.org/10.1016/j.ssi.2014.02.005

LiNbO3 and LiTaO3 are isomorphous and Nb and Ta have the same valence electron configuration and the same ionic radii. This suggests the use of Ta as a tracer to probe the self-diffusion of Nb in LiNbO3. The diffusion system consisted of a 20 nm laye...

The temporal decay of mass accretion in young stars is a fundamental tracer of the early evolution of circumstellar discs. Through population syntheses, we study how correlated uncertainties between the estimated parameters of young stars (luminosity...
