Statistical analysis of acoustic wave power and flows around solar active regions

Kavli Affiliate: Philip H. Scherrer | Summary:We analyze the effect of a sunspot in its quiet surroundings applying a helioseismic technique on almost three years of Helioseismic and Magnetic Imager (HMI) observations obtained during solar cycle 24 to further study the sunspot structure below the solar surface. The attenuation of acoustic waves with frequencies lower […]

The 2-component BKP Grassmanian and simple singularities of type D

Kavli Affiliate: Todor Milanov | Summary:It was proved in 2010 that the principal Kac–Wakimoto hierarchy of type $D$ is a reduction of the 2-component BKP hierarchy. On the other hand, it is known that the total descendant potential of a singularity of type $D$ is a tau-function of the principal Kac–Wakimoto hierarchy. We find explicitly […]

Defining Pathway Assembly and Exploring its Applications

Kavli Affiliate: Stuart Marshall | Summary:How do we estimate the probability of an abundant objects’ formation, with minimal context or assumption about is origin? To explore this we have previously introduced the concept of pathway assembly (as pathway complexity), in a graph based context, as an approach to quantify the number of steps required to […]

Observation of $h_1(1380)$ in the $J/ψto η^prime Kbar K π$ Decay

Kavli Affiliate: Wei Gao | First 5 Authors: M. Ablikim, M. Ablikim, , , | Summary: Using $1.31 times 10^9$ $J/ψ$ events collected by the BESIII detector at the BEPCII $e^+e^-$ collider, we report the first observation of the $h_1(1380)$ in $J/ψto η^prime h_1(1380)$ with a significance of more than ten standard deviations. The mass […]

Solar System Ice Giants: Exoplanets in our Backyard

Kavli Affiliate: George Clark | Summary:Future remote sensing of exoplanets will be enhanced by a thorough investigation of our solar system Ice Giants (Neptune-size planets). What can the configuration of the magnetic field tell us (remotely) about the interior, and what implications does that field have for the structure of the magnetosphere; energy input into […]
