Solar sail capture trajectories at Mercury [PDF]
, 2002 Mercury is an ideal environment for future planetary exploration by solar sail since it has proved difficult to reach with conventional propulsion and hence remains largely unexplored.

Sublimation of ice particles from rocket exhausts in the upper atmosphere [PDF]
, 2003 The process of sublimation of ice particles from a rocket exhaust in the upper atmosphere is examined. Heating by solar radiation and losses of energy by means thermal radiation and sublimation are taken into account in the thermal balance of the ice ...

Solar flux emergence : a three-dimensional numerical study [PDF]
, 2008 Flux is continually emerging on the Sun, making its way from the solar interior up into the atmosphere. Emergence occurs on small-scales in the quiet Sun where magnetic fragments emerge, interact and cancel and on large-scales in active regions where ...

Magnetohydrostatic modeling of the solar atmosphere
Science China Technological Sciences, 2022 Understanding structures and evolutions of the magnetic fields and plasma in multiple layers on the Sun is very important. A force-free magnetic field which is an accurate approximation of the solar corona due to the low plasma $β$ has been widely studied and used to model the coronal magnetic structure.
