Non-magnetic photospheric bright points in 3D simulations of the solar atmosphere
Flavio Calvo, Oskar Steiner, Bernd Freytag
Context. Small-scale bright features in the photosphere of the Sun, such as faculae or G-band bright points, appear in connection with small-scale magnetic flux concentrations. Aim…
The W. M. Keck Observatory infrared vortex coronagraph and a first image of HIP79124 B
Eugene Serabyn, Elsa Huby, Keith Matthews +22
An optical vortex coronagraph has been implemented within the NIRC2 camera on the Keck II telescope and used to carry out on-sky tests and observations. The development of this new…
Characterization of the inner disk around HD 141569 A from Keck/NIRC2 L-band vortex coronagraphy
Dimitri Mawet, Élodie Choquet, Olivier Absil +22
HD 141569 A is a pre-main sequence B9.5 Ve star surrounded by a prominent and complex circumstellar disk, likely still in a transition stage from protoplanetary to debris disk phas…
Discovery of a low-mass companion inside the debris ring surrounding the F5V star HD206893
Julien Milli, Pascale Hibon, Valentin Christiaens +30
Uncovering the ingredients and the architecture of planetary systems is a very active field of research that has fuelled many new theories on giant planet formation, migration, com…
Towards multistage modelling of protein dynamics with monomeric Myc oncoprotein as an example
Jiaojiao Liu, Jin Dai, Jianfeng He +2
We propose to combine a mean field approach with all atom molecular dynamics into a multistage algorithm that can model protein folding and dynamics over very long time periods yet…
Radio detection of air showers with the ARIANNA experiment on the Ross Ice Shelf
S. W. Barwick, D. Z. Besson, A. Burgman +15
The ARIANNA hexagonal radio array (HRA) is an experiment in its pilot phase designed to detect cosmogenic neutrinos of energies above 10^16 eV. The most neutrino-like background st…
