Ram pressure effect stars
Young stellar populations are found in such clumps. Dense gas clumps with N_H >ġ0 Msun pc^-2 are easily identified in extraplanar regions, but no significant Star formation by a factor of two within ~200 Myr. In contrast, strong winds rapidlyīlow away neutral and molecular hydrogen gas from the galaxy, suppressing the Oriented face-on or ~80% when it is edge-on. Moderate ICM winds facilitate gasĬollapsing, increasing the total star formation rates by ~40% when the wind is Whereas turbulent pressure provides support against ram pressure in the central Galactic disk are significantly stripped in the presence of the moderate winds, T108 yr Isolated Stripped Isolated Stripped Density profile Face-on Edge-on S F R S F R 2x 3x (Kronberger+2008) RAM.

By compressing the gas RAM pressure can enhance star formation by a factor of 2 or more.
