What Role Do Shock Waves Play in Star Formation from Interstellar Clouds?

AI Thread Summary
Shock waves from external events, such as supernovae or density waves from spiral arms, play a crucial role in star formation by triggering the condensation of interstellar clouds. These shock waves lead to the formation of dense regions known as Barnard's objects and Bok's globules, where density and temperature increase significantly. This process ultimately results in the creation of protostars, which are the early stages of star development. Understanding the impact of shock waves is essential for comprehending the mechanisms behind star formation in the universe. The discussion highlights the importance of these phenomena in the evolution of stellar bodies.

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.
 

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
