What does "Natal Kick" mean?
Table of Contents
Natal kick refers to the sudden movement given to a star when it is born, especially for neutron stars and black holes. When these stars form, they can receive a kick, which can change their speed and direction. This kick happens due to the explosion that occurs when the star dies and collapses.
Importance of Natal Kicks
The strength and direction of the natal kick can influence where the new star ends up in space. For example, a strong kick can push a star far away from its original location. This is important for understanding how stars move and interact in our galaxy.
Effects on Binary Systems
In systems where two stars are closely tied together, known as binary systems, the natal kick can affect both stars. If one star gets a strong kick, it can cause the entire system to change its orbit or separate completely. This is a key factor in determining the life and fate of binary star pairs.
Connection to Observations
Scientists study natal kicks to explain the movement and formation of various star systems, including black holes and neutron stars that are found close to other stars. Understanding these kicks helps to make sense of how some of these systems appear today, including those detected by space missions.
