A planar multipole ion trap
M. Debatin, M. Kröner, J. Mikosch +6
We report on the realisation of a chip-based multipole ion trap manufactured using micro-electromechanical systems (MEMS) technology. It provides ion confinement in an almost field…
High-Resolution Spectroscopy of the Yellow Hypergiant Rho Cassiopeiae from 1993 Through the Outburst of 2000-2001
A. Lobel, A. K. Dupree, R. P. Stefanik +7
We present an overview of the spectral variability of the peculiar F-type hypergiant Rho Cas, obtained from our long-term monitoring campaigns over the past 8.5 years with four spe…
Observation of roton emission from a quantized vortex
A. Lester, N. Morrison, F. Novotny +5
Turbulence in inviscid quantum fluids offers unparalleled access to the universal principles of non-equilibrium dynamics, spanning a vast range of length scales from macroscopic fl…
Wind structure of late B supergiants I. Multi-line analyses of near-surface and wind structure in HD 199 478 (B8 Iae)
N. Markova, R. Prinja, H. Markov +4
We provide a quantitative analysis of time-variable phenomena in the photospheric, near-star, and outflow regions of the late-B supergiant (SG) HD 199478. The analysis is based pri…
The Millennium Outburst of the Cool Hypergiant Rho Cassiopeiae: Spectroscopy and Modeling
A. Lobel, A. K. Dupree, R. P. Stefanik +7
Between 2000 June and September an exceptional variability phase occurred in the peculiar F-type hypergiant Rho Cas, when the V-brightness dimmed by at least a full magnitude. The…
Tensile properties of all-polymeric syntactic foam composites: experimental characterization and mathematical modelling
Z. Yousaf, N. Morrison, W. J. Parnell
All-polymer syntactic foams are studied under large strain cyclic and monotonic tensile loading in order to reveal their tensile stress-strain behaviour, recoverability, tensile st…
