Magnetohydrodynamic Perspective on the Disappearance of Mercury’s Bow Shock by Helios Data Exploration

In the magnetohydrodynamic (MHD) perspective, the planet’s bow shock would disappear when the fast-mode Mach number ( M _F ) of the solar wind is less than one. Compared to Earth, Mercury is subject to a lower M _F solar wind due to its proximity to the Sun, resulting in a higher possibility of the...
