Differential Rotation in Solar Convective Dynamo Simulations
Yuhong Fan, Fang Fang
We carry out a magneto-hydrodynamic (MHD) simulation of convective dynamo in the rotating solar convective envelope driven by the solar radiative diffusive heat flux. The simulatio…
Magnetic null points in kinetic simulations of space plasmas

We present a systematic attempt to study magnetic null points and the associated magnetic energy conversion in kinetic Particle-in-Cell simulations of various plasma configurations…
Far-UV spectroscopy of the planet-hosting star WASP-13: high-energy irradiance, distance, age, planetary mass-loss rate, and circumstellar environment
L. Fossati, K. France, T. Koskinen +3
Several transiting hot Jupiters orbit relatively inactive main-sequence stars. For some of those, the logR'HK activity parameter lies below the basal level (-5.1). Two explanations…
Campaign 9 of the Mission: Observational Parameters, Scientific Drivers, and Community Involvement for a Simultaneous Space- and Ground-based Microlensing Survey
Calen B. Henderson, Radosław Poleski, Matthew Penny +118
's Campaign 9 (C9) will conduct a 3.7 deg survey toward the Galactic bulge from 7/April through 1/July of 2016 that will leverage the spatial separation between…
Magnetic flux concentrations from turbulent stratified convection
P. J. Käpylä, A. Brandenburg, N. Kleeorin +2
(abridged) Context: The mechanisms that cause the formation of sunspots are still unclear. Aims: We study the self-organisation of initially uniform sub-equipartition magnetic fiel…
Interplay of waves and eddies in rotating stratified turbulence and the link with kinetic-potential energy partition
Raffaele Marino, Duane Rosenberg, Corentin Herbert +1
The interplay between waves and eddies in stably stratified rotating flows is investigated by means of world-class direct numerical simulations using up to grid points. St…
Nitrate ions spikes in ice cores are not suitable proxies for solar proton events
Katharine A. Duderstadt, Jack E. Dibb, Charles H. Jackman +5
Nitrate ion spikes in polar ice cores are contentiously used to estimate the intensity, frequency, and probability of historical solar proton events, quantities that are needed to…
Large-scale flow generation by inhomogeneous helicity
Nobumitsu Yokoi, Axel Brandenburg
The effect of kinetic helicity (velocity--vorticity correlation) on turbulent momentum transport is investigated. The turbulent kinetic helicity (pseudoscalar) enters the Reynolds…
The Pluto system: Initial results from its exploration by New Horizons
S. A. Stern, F. Bagenal, K. Ennico +148
The Pluto system was recently explored by NASA's New Horizons spacecraft, making closest approach on 14 July 2015. Pluto's surface displays diverse landforms, terrain ages, albedos…
16 Years of Ulysses Interstellar Dust Measurements in the Solar System: I. Mass Distribution and Gas-to-Dust Mass Ratio
Harald Krüger, Peter Strub, Eberhard Gruen +1
In the early 1990s, contemporary interstellar dust (ISD) penetrating deep into the heliosphere was identified with the in-situ dust detector on board the Ulysses spacecraft. Betwee…
Measurements and Modeling of Total Solar Irradiance in X-Class Solar Flares
Christopher Samuel Moore, Phillip Clyde Chamberlin, Rachel Hock
The Total Irradiance Monitor (TIM) from NASA's SOlar Radiation and Climate Experiment (SORCE) can detect changes in the Total Solar Irradiance (TSI) to a precision of 2 ppm, allowi…
The Apache Point Observatory Galactic Evolution Experiment (APOGEE)
Steven R. Majewski, Ricardo P. Schiavon, Peter M. Frinchaboy +75
The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its systematic, homogeneo…
X-ray to NIR emission from AA Tauri during the dim state - Occultation of the inner disk and gas-to-dust ratio of the absorber
P. C. Schneider, K. France, H. M. Günther +5
AA Tau is a well-studied, nearby classical T Tauri star, which is viewed almost edge-on. A warp in its inner disk periodically eclipses the central star, causing a clear modulation…
Solar Wind at 33 AU: Setting Bounds on the Pluto Interaction for New Horizons
F. Bagenal, P. A. Delamere, H. A. Elliott +7
The NASA New Horizons spacecraft flies past Pluto on July 14, 2015, carrying two instruments that detect charged particles. Pluto has a tenuous, extended atmosphere that is escapin…
Driving Solar Spicules and Jets with Magnetohydrodynamic Turbulence: Testing a Persistent Idea
Steven R. Cranmer, Lauren N. Woolsey
The solar chromosphere contains thin, highly dynamic strands of plasma known as spicules. Recently, it has been suggested that the smallest and fastest (Type II) spicules are ident…
Waves and vortices in the inverse cascade regime of stratified turbulence with or without rotation
Corentin Herbert, Raffaele Marino, Duane Rosenberg +1
We study the partition of energy between waves and vortices in stratified turbulence, with or without rotation, for a variety of parameters, focusing on the behavior of the waves a…
