What are stars called that wink?

Answer 1

The Earth's atmosphere, which is always moving, makes stars appear to be twinkling.

A star that really is 'winking' is most likely an eclipsing binary star - two stars orbiting each other.

Answer 2

Imaginary. Stars shine pretty constantly until they die, and their deaths are often spectacular. But they don't "wink".

Perhaps you meant "twinkle", in which case they're just stars. The twinkling effect is caused by atmospheric disturbances, and it rather famously doesn't happen to planets, since even though you can't easily tell by eye, they aren't effectively point sources as seen from Earth.

Or then again, perhaps you meant "blink", as happens with pulsars.

I think that I know what this question means. The answer's "eclipsing binaries".

Such binary systems (with short periods) are said to "wink", especially if one of

the stars is much brighter than the other. A famous example is "Algol".

Answer 3

Stars that appear to "wink" or flicker in brightness are typically referred to as variable stars. These stars exhibit changes in their luminosity over time due to various physical processes happening within them, such as pulsations, eclipses in binary systems, or eruptions.

Answer 4

As a small/young child, the stars that wink would be called 'twinkling stars'.

Answer 5

an eclipsing binary pair
