Observing stellar bow shocks

摘要: For stars, the bow shock is typically boundary between their stellar wind and interstellar medium. Named for wave made by a ship as it moves through water, can be created in space when two streams of gas collide. The actually filled with medium consisting tenuous dust. Stars are emitting flow called wind. Stellar eventually bumps into medium, creating an interface where physical conditions such density pressure change dramatically, possibly giving rise to wave. Here we discuss some literature on shocks show observations them, enhanced image processing techniques, particular recently proposed AstroFracTool software.
