X-ray tomography of a cometary bow shock

open access: yes, 2005
The volume intensity of the cometary X-ray emission is enhanced behind the bow shock by a factor of up to three. This effect offers the opportunity to identify the bow shock by a tomographic method in X-ray images of comets.

The Influence of the Stretch of Mini‐Magnetospheres Formed by Crustal Fields on the Martian Bow Shock Location

open access: yesGeophysical Research Letters
Mars lacks an intrinsic dipolar magnetic field but possesses strong crustal magnetic fields scattered across its surface. There has been an ongoing debate about how these crustal fields influence the bow shock, the outermost plasma boundary of the ...

Review of boundary model studies in the Venusian and Martian induced magnetosphere

open access: yes地球与行星物理论评
Although Venus and Mars do not have a global magnetic field but have atmospheres and ionospheres. During their coupling with the solar wind, the induced magnetospheres are created, as well as the boundaries of the bow shock and the magnetic pileup ...

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

open access: yesThe Astrophysical Journal
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.

The bow shock and mach disk of HH 111V

open access: yes, 1993
We present spatially resolved line profiles in Hα and [S II] λλ16716, 6731 across the working surface region in the Herbig-Haro object HH 111V. Data were acquired with the Rutgers/CTIO imaging Fabry-Perot interferometer on the CTIO 4 m telescope at ∼1″.3

Entropy Generation Across Earth's Bow Shock

open access: yes, 2011
Earth's bow shock is a transition layer that causes an irreversible change in the state of plasma that is stationary in time. Theories predict entropy increases across the bow shock but entropy has never been directly measured.
