The Kelvin-Helmholtz (KH) instability occurs in multiple heliospheric (solar-wind stream interfaces, planetary magnetospheres, cometary tails, heliopause flanks) and interstellar (…
Observing Orbital Decay in the Ultracompact Hot Subdwarf Binary System ZTFJ213056.71+442046.5
Paul Teckenburg, Thomas Kupfer, Alex J. Brown +7
Ultracompact Galactic binary systems (UCBs) emit low-frequency gravitational waves (GWs). The emission of GWs is causing these systems to lose angular momentum, which is detectable…
Nature of Transonic Sub-Alfvénic Turbulence and Density Fluctuations in the Near-Sun Solar Wind: Insights from Magnetohydrodynamic Simulations and Nearly-Incompressible Models
Giuseppe Arrò, Hui Li, Gary P. Zank +2
Recent Parker Solar Probe measurements have revealed that solar wind (SW) turbulence transits from a subsonic to a transonic regime near the Sun, while remaining sub-Alfvénic. Thes…
Role of magnetic shear distribution on the formation of eruptive flux ropes
Samrat Sen, Sushree S Nayak, Patrick Antolin
Erupting flux ropes play crucial role in powering a wide range of solar transients, including flares, jets, and coronal mass ejections. These events are driven by the release of st…

Electromagnetic Electron Kelvin-Helmholtz Instability
H. Che, G. P. Zank
On electron kinetic scales, ions and electrons decouple, and electron velocity shear on electron inertial length can trigger electromagnetic (EM) electron Kelvin-Helmhol…
A study of particle acceleration, heating, power deposition, and the damping length of kinetic Alfvén waves in non-Maxwellian coronal plasma
S. Ayaz, Gary P. Zank, Imran A. Khan +2
The heating of the solar corona and solar wind, through suprathermal particles and kinetic Alfvén waves within the 0 - 10 range, has been a subject of great interest…
Interstellar Neutral Hydrogen in the Heliosphere: New Horizons Observations in the Context of Models
P. Swaczyna, M. Bzowski, K. Dialynas +12
Interstellar neutral (ISN) hydrogen is the most abundant species in the outer heliosheath and the very local interstellar medium (VLISM). Charge exchange collisions in the outer he…
CME Deflection and East-West Asymmetry of ESP Intensity in Solar Cycles 23 and 24
Adolfo Santa Fe Dueñas, Robert W. Ebert, Gang Li +4
We investigate the East-West asymmetry in energetic storm particle (ESP) heavy ion intensities at interplanetary shocks driven by coronal mass ejections (CMEs) during solar cycles…
Sequential Small Coronal Mass Ejections Observed In~situ and in White-Light Images by Parker Solar Probe

Erupting magnetic flux ropes (MFRs) play a crucial role in producing solar flares. However, the formation of erupting MFRs in complex coronal magnetic configurations and their subs…
Magnetohydrodynamics simulation of magnetic flux rope formation in a quadrupolar magnetic field configuration
Sanjay Kumar, Avijeet Prasad, Sushree S. Nayak +2
Magnetic flux ropes (MFRs) play an important role in high-energetic events like solar flares and coronal mass ejections in the solar atmosphere. Importantly, solar observations sug…

Prospective Implications of EUV Coronal Plumes for Magnetic-network Genesis of Coronal Heating, Coronal-hole Solar Wind, and Solar-wind Magnetic-field Switchbacks
Ronald L. Moore, Sanjiv K. Tiwari, Navdeep K. Panesar +1
We propose that coronal heating in EUV coronal plumes is weaker, not stronger, than in adjacent non-plume coronal magnetic funnels. This expectation stems from (i) the observation…
