Cavitons Associated with Ion-Acoustic-Like Waves in Foreshock Transients
Runyi Liu, Terry Liu, Xin An +2
Foreshock transients upstream of the Earth's bow shock, such as foreshock bubbles and hot flow anomalies, are often characterized by reduced-density cores and strong plasma fluctua…
Plasma refilling of the lunar wake: plasma-vacuum interactions, electrostatic shocks, and electromagnetic instabilities
Xin An, Vassilis Angelopoulos, Terry Z. Liu +3
A plasma void forms downstream of the Moon when the solar wind impacts the lunar surface. This void gradually refills as the solar wind passes by, forming the lunar wake. We invest…
Cross-scale energy transfer from fluid-scale Alfvén waves to kinetic-scale ion acoustic waves in the Earth's magnetopause boundary layer
Xin An, Anton Artemyev, Vassilis Angelopoulos +3
In space plasmas, large-amplitude Alfvén waves can drive compressive perturbations, accelerate ion beams, and lead to plasma heating and the excitation of ion acoustic waves at ki…
Transient Upstream Mesoscale Structures: Drivers of Solar-Quiet Space Weather
Primož KajdiÄ, Xóchitl Blanco-Cano, Lucile Turc +12
In recent years, it has become increasingly clear that space weather disturbances can be triggered by transient upstream mesoscale structures (TUMS), independently of the occurrenc…
