  2. Shock wave - Wikipedia

    en.wikipedia.org/wiki/Shock_wave

    In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium, but is characterized by an abrupt, nearly discontinuous, change in pressure , temperature , and ...

    en.wikipedia.org/wiki/Shock_waves_in_astrophysics

    Shock waves are common in astrophysical environments. [1]Because of the low ambient density, most astronomical shocks are collisionless.This means that the shocks are not formed by two-body Coulomb collisions, since the mean free path for these collisions is too large, often exceeding the size of the system.

    To get a larger bow-shock catalog The Milky Way Project (a Citizen Science project) aims to map infrared bow-shocks in the galactic plane. This larger catalog will help to understand the stellar wind of massive stars. [18] Zeta Ophiuchi is the most famous bowshock of a massive star. Image is from the Spitzer Space Telescope.
