A star changes over time as it ages because its internal composition changes as nuclear fusion reaction in the star's core convert one element into another
this is simple its used to describe the star sizes through a process that is complicated and people see this through the life cycle of a star as the minerals inside the star change over time
Im no astrophysicist but an older star would consume more of its hydrogen over time in comparison to helium through its fusion process. Over time concetrations would change resulting in a higher helium to hydrogen ratio.
The proper motion of a star or object is measured by its angular change in position on the sky over time, typically in units of arcseconds per year. This motion is caused by the true motion of the star through space, as well as the motion of Earth around the Sun.
Mira Ceti, also known as Omicron Ceti, is a red giant star with an effective temperature of approximately 3,000 to 3,500 Kelvin. This relatively low temperature contributes to its reddish appearance. As a variable star, its brightness can change significantly over time, but its surface temperature remains within this range.
Basically they stay the same, although over tens of thousands of years, they change slightly.

In manual star delta starter, the change over from star to delta does not happen automatically. The operator or user puts on the starter, and after few seconds he pushes a lever or handle to change over to Delta. In automatic method, change over happens from star to delta using an automatic preset timer.
A change over time is often referred to as a gradual change.
Yes, friends do and will change over time. Every person changes over time.
