SUMMARY

Shock waves play a critical role in star formation from interstellar clouds by triggering the condensation of gas and dust into denser regions known as 'Barnard's objects' and 'Bok's globules'. These regions eventually evolve into protostars as density and temperature increase. External events, such as the explosion of nearby stars or density waves from spiral arms of galaxies, initiate these shock waves, facilitating the star formation process. Understanding these dynamics is essential for comprehending stellar evolution.

PREREQUISITES
  • Knowledge of interstellar medium dynamics
  • Familiarity with star formation processes
  • Understanding of shock wave physics
  • Basic concepts of protostar development
NEXT STEPS
  • Research the role of shock waves in astrophysics
  • Study the characteristics of Barnard's objects and Bok's globules
  • Explore the impact of supernovae on star formation
  • Investigate the lifecycle of protostars in various environments
USEFUL FOR

Astronomers, astrophysicists, and students studying stellar formation and interstellar medium dynamics will benefit from this discussion.

I would like to ask that what character does shock wave (not pressure wave ) play in the forming of a star from the interstellar cloud?

From: http://nrumiano.free.fr/Estars/birth.html

Following an external event, the shock wave of a nearby exploding star for instance, or the density wave of a spiral arm of the galaxy, some parts of this cloud will condense in regions which are called 'Barnard's objects' and 'Bok's globules'. These areas, where density is significantly growing along with the temperature, are called protostars.

Thanks for your help.
