The impact of a fossil magnetic field on dipolar mixed-mode frequencies in sub- and red-giant stars

L. Bugnet, V. Prat, S. Mathis +5

Stars more massive than M are known to develop a convective core during the main-sequence: the dynamo process triggered by this convection could be the origin of…

Upper Atmosphere Smoke Injection from Large Areal Fires

Stephanie Redfern, Julie K. Lundquist, Owen B. Toon +3

Large fires can inject smoke into the upper troposphere and lower stratosphere. Detailed fire simulations allow for assessment of how local weather interacts with these fires and a…

Electron Densities in the Solar Corona Measured Simultaneously in the Extreme-Ultraviolet and Infra-Red

Jaroslav Dudík, Giulio Del Zanna, Ján Rybák +5

Accurate measurements of electron density are critical for determination of the plasma properties in the solar corona. We compare the electron densities diagnosed from Fe XIII line…

Evolution of three-dimensional coherent structures in Hall magnetohydrodynamics

Kamlesh Bora, Ramit Bhattacharyya, Piotr K. Smolarkiewicz

The work extends the computational model EULAG-MHD to include Hall magnetohydrodynamics (HMHD)---important to explore physical systems undergoing fast magnetic reconnection at the…

The intensity and evolution of the extreme storms in January 1938

Hisashi Hayakawa, Kentaro Hattori, Alexei A. Pevtsov +7

Major solar eruptions occasionally direct interplanetary coronal mass ejections (ICMEs) to Earth and cause significant geomagnetic storms and low-latitude aurorae. While single ext…

Alfvénic Thermospheric Upwelling in a Global Geospace Model

Benjamin Hogan, William Lotko, Kevin Pham

Motivated by low-altitude cusp observations of small-scale (~ 1 km) field-aligned currents (SSFACs) interpreted as ionospheric Alfvén resonator modes, we investigated the effects o…
