What else can I help you with?
What are pulsating stars?
That refers to star that change their size, and therefore their brightness, in a repetitive pattern.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
Which two groups of stars can have similar brightness?
Variable stars and main sequence stars can have similar brightness. Variable stars, like Cepheid variables, can fluctuate in brightness over time, while main sequence stars maintain a relatively stable brightness due to their fusion processes.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.
Why do you study stars?
To learn more about the universe. For me personally, I enjoy getting outside at night and observing. I look at stars that change in brightness - variable stars - and this contributes to our ongoing long-term database.
What is the measure of a stars brightness?
Magnitude.
Is shape affects the brightness of the stars?
no
In main-sequence stars how does brightness relate to temperature?
The brightness is very similar to the temperature, the brightness relies on the temperature
What determines how bright stars are?
Size and temperature determine the brightness of stars.
What is the temperature and brightness of stars indicated by?
color
The temperature and brightness of stars are indicated by?
