Scientists consider a red star to be a type of star that has a relatively low surface temperature, typically ranging from about 2,500 to 3,500 degrees Celsius. These stars emit light primarily in the red and infrared wavelengths, giving them their characteristic color. Red stars are often classified as red dwarfs or red giants, depending on their size and stage in the stellar lifecycle. They are generally cooler and less massive than other types of stars, like yellow or blue stars.
What else can I help you with?
What does the red shift tell scientists?
The redshift tells scientists how fast a star or galaxy is moving away from us.
How do you use red giant in a sentence?
Our sun is expected to become a red giant within a few billion years. The red giant star Antares has a diameter 800 times that of the Sun.
How do scientists tell if a star is warm or cold?
Scientists determine a star's temperature by analyzing its spectrum of light. The color and intensity of certain lines in a star's spectrum reveal its temperature. Hotter stars appear blue or white, while cooler stars appear red.
What can scientists learn from a stars light?
Scientists learn the temperature of the stars light for exampleif the star is red- it's cold but it's blue- it's hot and if it's WHITE- IT'S VERY HOT ! that's how you know the temperate of stars (Determining the color)
What is the meaning of a red star on a house?
A red star on a house may indicate various meanings depending on cultural context. In some cultures, a red star can symbolize protection or good luck, while in others it may represent a particular political affiliation or historical significance. It is important to consider the specific cultural and regional context when interpreting the meaning of a red star on a house.
What does the red shift tell scientists?

What will a medium-sized star be called?
Perhaps it is called the Betelgeuse * * * * * But only if you consider a red supergiant to be a medium-sized star!
How do you use red giant in a sentence?
Our sun is expected to become a red giant within a few billion years. The red giant star Antares has a diameter 800 times that of the Sun.

Rigel is a blue-white star wich indicates that is a very hot star. you might think red stars are the hottest but no, the hottest are blue-white.

How do scientists use computers to measure distance from stars?
From what I remember in two geology classes, scientists measure the distance between a star and Earth by comparing "red shift," a shifting of certain bands of light toward the "red" end of the spectrum. The further the shifting, the greater the distance.
How do scientists determine the element present in a star?
By the star's spectrum.
Is red giant a star or a type of star?
Red giant is a type of star.
What can be said about a red star and a blue star?
A red star is cool whereas a blue star is hot.
How do you say red star or star of red in Chinese?
