What is the relationship between the color and the temperature of star?
The relationship is that the color is an indication of the star's surface temperature. For example, red stars are cooler, while blue stars are hotter. You can find more details in the Wikipedia article "Stellar classification".
Is a white and blue star hotter then a red star?
Yes. See the Wikipedia article on "Stellar classification". For example, a class "O" star (blue) has a surface temperature greater than 30,000 K, a class "A" star (white) has a surface temperature of 7,500 - 10,000 K, and a class "M" star (red) has a surface temperature of 2400-3700 K. (All temperatures use the absolute scale.)
Is the star Rasalhague a super giant?
Alpha Ophiuchi is considered to have a stellar classification of A5 III, which makes it a "normal" giant, not a supergiant.
When does stellar nucleosynthesis start in a star?
When the temperature in the core reaches 10 million degrees Kelvin.
Is our sun an O star?
No, our sun is not an O star. Our sun is classified as a G-type star, specifically a G2V star, which is a main sequence star with a surface temperature of about 5,500 degrees Celsius. O stars are much hotter and more massive than our sun, with surface temperatures exceeding 30,000 degrees Celsius.

What type of star is a Enif?
It is a star that has entered the super-giant phase. Its stellar classification is K2 1b.
Is our Sun is an O star.?
== == No our Sun is a G2V star. See related link for more information on stellar classification

What type of star is Sadalmelik?
Alpha Aquarii -also known as Sadalmelik- is a supergiant star in the Aquarius constellation. It has a stellar classification of G2 lb.
Do scientists use stellar parallax to determine a star's temperature?
No, scientists do not use stellar parallax to determine a star's temperature. Stellar parallax is a technique used to measure the distance to stars by tracking their apparent shift in position as the Earth orbits the Sun. A star's temperature is typically determined by analyzing its spectrum, which provides information about the star's composition and temperature through features such as absorption lines.
What is a stellar spectra?
Stellar spectra are graphs or visual representations of the intensity of light emitted by a star at different wavelengths. They provide information about the star's temperature, chemical composition, and motion towards or away from Earth. Studying stellar spectra is crucial for understanding the properties and evolution of stars.
The entire spectral classification of the sun is?
The Sun is classified as a G-type main-sequence star (G dwarf) under the Harvard spectral classification system, specifically as G2V. This classification indicates that it has a surface temperature of approximately 5,500 degrees Celsius (about 5,800 Kelvin) and emits a yellowish light. The "G" signifies its color and temperature, while the "V" denotes its status as a main-sequence star, which is a stage in stellar evolution where it fuses hydrogen into helium in its core.
What was Henry Norris Russell famous for?
Henry Norris Russell was an American astronomer renowned for his contributions to the field of astrophysics, particularly in the study of stellar classification and the Hertzsprung-Russell diagram, which illustrates the relationship between a star's luminosity and its temperature. He played a significant role in advancing our understanding of stellar evolution and the structure of the Milky Way galaxy. Russell's work laid the foundation for modern stellar classification systems and helped in deciphering the life cycles of stars.

How do positive and negative numbers relate to a star's temperature?
the positive is the dimmest star. the negative is the brightest star.
