Evolution of lunar wake potentials: structure, energy conversion, and their imprints on velocity distributions
Xin An, Vassilis Angelopoulos, Jasper S. Halekas +4
We study the evolution of electric potentials in the lunar wake. The wake potential exhibits two distinct spatial scales. The macroscopic scale arises from solar wind expansion int…
Inferring lunar wake potentials from electron phase space densities
Xin An, Shaosui Xu, Vassilis Angelopoulos +4
Inferring electric potentials from electron phase space density measurements in the lunar wake is complicated by two challenges: the asymmetry between the sunward and anti-sunward…
Ion pickup and velocity space thermalization at outer planet moons
Xin An, Miranda Chang, Hao Cao +2
Ion pickup at the outer planets' active moons is a fundamental plasma process in which newly ionized particles from moon exospheres interact with the ambient corotating plasma and…
ARTEMIS observations of electrostatic shocks inside the lunar wake
Terry Z. Liu, Xin An, Vassilis Angelopoulos +1
When the solar wind encounters the Moon, a plasma void forms downstream of it, known as the lunar wake. In regions where the magnetic field is quasi-parallel to the plasma-vacuum b…
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…
Excitation of whistler-mode waves by an electron temperature anisotropy in a laboratory plasma
Donglai Ma, Xin An, Jia Han +6
Naturally-occurring whistler-mode waves in near-Earth space play a crucial role in accelerating electrons to relativistic energies and scattering them in pitch angle, driving their…
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 kin…
Equatorial source of oblique electromagnetic ion cyclotron waves: peculiarities in the ion distribution function
David S. Tonoian, Xiao-Jia Zhang, Anton Artemyev +1
Electromagnetic ion cyclotron (EMIC) waves are important for Earth's inner magnetosphere as they can effectively drive relativistic electron losses to the atmosphere and energetic…
