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 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
