Research Progress on Solar Small-Scale Dynamo
Wen-Jie Jiang, Lei Ni, Chun-Lan Jin +2
The small-scale solar dynamo theory, as the core mechanism explaining the origin of the persistent, disperse weak magnetic field in the quiet Sun regions, has made significant prog…
Radiative MHD Studies of Solar Spicules: Driving Mechanisms and the Role of Background Magnetic Field
Jin Li, Lei Ni, Robertus Erdélyi +3
We conduct 2.5D radiative magnetohydrodynamic (MHD) simulations to investigate the driving mechanisms of the solar spicules in coronal holes and how the different background magnet…
Energy and mass transport associated with impulsive spicular flows in solar coronal holes
Lei Ni, Jun Lin, Tanmoy Samanta +3
How the solar atmosphere is heated from a temperature of about \,K in the lower atmosphere to about \,MK in the corona has challenged the astrophysical community…
Three dimensional magnetic reconnection mediated with plasmoids and the resulted multi-thermal emissions in the cool atmosphere of the Sun
Guanchong Cheng, Lei Ni, Robert Cameron +3
Flux emergence is ubiquitous in the Sun's lower atmosphere, where the emerging magnetic flux can reconnect with the pre-existing magnetic field. We investigate plasmoid formation a…
The effect of plasma- on the heating mechanisms during magnetic reconnection in partially ionized low solar atmosphere
Abdullah Zafar, Lei Ni, Kaifeng Kang +5
We performed numerical simulations of magnetic reconnection with different strength of magnetic fields from the solar photosphere to the upper chromosphere. The main emphasis is to…
Numerical simulation of oscillatory magnetic reconnection modulated by solar convective motions
Yifu Wang, Lei Ni, Guanchong Cheng +3
Oscillatory magnetic reconnection is a periodic magnetic reconnection process, during which the current sheet's orientation and the magnetic connections change periodically. This p…
