The early history of stars has not received much attention in traditional theories of stellar evolution up until now.
Stars in their "early years," from newborns to teenagers, provide a significant challenge to science. It is challenging to trace the process of star creation due to its complexity.
Observing a star's oscillations is one of the very few ways to find out more about a star's age, structure, or formation.
Because of the increased ability to make exact observations with space observatories like TESS, Kepler, and James Webb, the study of star oscillations has advanced considerably in recent years.
As long as stars are not yet converting hydrogen into helium in their cores, they are referred to as "children." They enter the main sequence following ignition when they become adults.
The pre-main sequence evolution has received little study because the phase is chaotic and challenging to model.
Only recent technological advancements have made it possible for us to get a closer look at the early stages of stars, specifically the time when the star first starts fusing hydrogen into helium.
It sounds obvious, yet the early vibrational modes of the star have an impact on its later pulsations. According to the conventional notion, the interval preceding ignition is simply unimportant.
Contrary to popular belief, minor adjustments to a composition can result in substantial changes to the tone. As a result, our newer models more accurately capture the oscillations in actual stars.
These are milestone moments for the better understanding of stars and their evolution process.
