they look at the star in, say, spring, then fall or summer then winter. we have to be on opposite sides of the star to see the parallax, so it takes about a year
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.
Parallax is a method used to find the distances of stars.
Parallax is the apparent shift in the position of an object when viewed from different angles. In astronomy, parallax is used to measure the distance to stars by observing how their positions change as the Earth orbits the Sun. By measuring the angle of the shift, scientists can calculate the distance to the star using trigonometry.
By the star's spectrum.
The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
A parallax is a change in apparent position, when YOU move. In astronomy, it usually refers to the change in the apparent position of a star, due to Earth's orbit around the Sun. It's there, whether you "use" it or not, but it is quite useful to determine distances of stars that are relatively close to us - since the farther a star is, the smaller will the parallax be. Even for the nearest star after the Sun, the parallax is smaller than one second (1/3600 of a degree).
Astronomers use the method of parallax to determine the distance to relatively close stars like Sirius. By measuring the apparent shift in position of the star as the Earth moves around the Sun, astronomers can calculate the star's distance based on trigonometry.
Earth isn't a star and doesn't (can't) have a parallax, becuse we use Earth's orbit as a baseline to measure parallax.
A Parallax is a thing in science A Spectrum is another thing in science :D Astronomers use these terms so if you are doing this for homework nice try. Try doing your own work for once.
yes sometimes
In 1838 Friedrich Bessel was able to measure the parallax of the nearby star 61 Cygni and thus determine its distance and independenly confirm the fact that the Earth orbits round the Sun.
Parallax helps because the bigger the parallax is the closer the star is. Knowing the distance helps to determine the "absolute magnitude" of a star, not just how bright it appears.
