Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016
E. Meza, B. Sicardy, M. Assafin +167
Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by th…
Interaction of magnetic fields with a vortex tube at solar subgranular scale
C. E. Fischer, G. Vigeesh, P. Lindner +3
Using high-resolution spectropolarimetric data recorded with the Swedish 1 m Solar Telescope, we have identified several instances of granular lanes traveling into granules. These…
Onset of penumbra formation
M. GarcÃa-Rivas, J. JurÄák, N. Bello González +3
Context. Fully fledged penumbrae have been widely studied both observationally and theoretically. Yet the relatively fast process of penumbra formation has not been studied closely…
Soft Interaction Between Dissolved Dendrimers: Theory and Experiment
C. N. Likos, M. Schmidt, H. Loewen +3
Using small-angle neutron scattering and liquid integral equation theory, we relate the structure factor of flexible dendrimers of 4th generation to their average shape. The shape…
Asteroid sizes determined with thermophysical model and stellar occultations
A. Choukroun, A. Marciniak, J. Äurech +165
Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…
Softening of the stiffness of bottlebrush polymers by mutual interaction
S. Bolisetty, C. Airaud, Y. Xu +5
We study bottlebrush macromolecules in a good solvent by small-angle neutron scattering (SANS), static light scattering (SLS), and dynamic light scattering (DLS). These polymers co…
The role of the chromospheric magnetic canopy in the formation of a sunspot penumbra
P. Lindner, C. Kuckein, S. J. González Manrique +3
While it is being conjectured that a chromospheric canopy plays a role in penumbra formation, it has been difficult to find observational evidence of the connectivity between the p…
Characterization of the umbra-penumbra boundary by the vertical component of the magnetic field -- Analysis of ground-based data from the GREGOR Infrared Spectrograph
P. Lindner, R. Schlichenmaier, N. Bello González
The vertical component of the magnetic field () was found to reach a constant value at the umbra-penumbra boundary of stable sunspots in a recent statistical study of Hino…
Structure and interaction of flexible dendrimers in concentrated solution
S. Rosenfeldt, M. Ballauff, P. Lindner +1
We study the influence of mutual interaction on the conformation of flexible poly(propyleneamine) dendrimers of fourth generation in concentrated solution. Mixtures of dendrimers w…
