You cannot determine the age of a star based on it's luminosity or spectral class.
However, you can make *assumptions*.
OB and A stars are massive and will have a short lifespan in the millions of years.
FG and K stars have a longer life period - in the billions of years.
KMWLY and T stars are stars those that cause problems.
Most stars in this class are red dwarfs, stars that are so low in mass that they have a low rate of nuclear fusion and last for tens of billions of years.
In general - and I mean in general - a redder shift, should indicate an older star but you cannot use the HR- Diagram to determine this.
What else can I help you with?
The angle of the star Polaris above the northern horizon can be used to determine an observer's?
... lattitude.... lattitude.... lattitude.... lattitude.
When is parallax used for?
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).
What is the name of the teleportation machine used in Star Trek?
In the fictional world of Star Trek the device used to Teleport people is called the Transporter.
What is Often used to determine the distance to nearby stars?
parallax
In which episode of Star Trek was pi used?
Wolf in the Fold
Binary star can be used to determine the of a star?
Mass
What factor is not used to determine a star's apparent magnitude?
how dense the star is
What instruments are used to determine the altitude of the north star?
Instruments such as a sextant or a quadrant can be used to determine the altitude of the North Star. By measuring the angle between the North Star and the horizon, navigators can determine their latitude.
What tool is used to determine the place of star?
Sextant.
Can a spectroscope be used to collect information about the chemical makeup of a star?
a spectroscope is the instrument used to determine the chemical makeup of a star.
Is the Japanese name for the Pleiades star cluster in Taurus constelltion?
Yes, the Japanese name for the Pleiades star cluster is "Subaru." In Japanese culture, the cluster has been associated with various myths and is often depicted as seven stars. The name "Subaru" also means "to unite" or "to gather," reflecting the cluster's appearance. This name is widely recognized today, particularly as it is also used by the automotive brand Subaru.
What is a word for a group of stars that appears in the night sky?
The word that is used for a group of stars in the night sky is a star cluster.
What can parallax be used to determine about a star?
Parallax is a method used to find the distances of stars.
What instruments are used to determine the alititude of the north star?
celestial navigation
Is a Subaru an animal?
Subaru is a car manufacturer owned by Fuji Heavy Industries. The word Subaru is a Japanese word used to describe a star cluster.
What is device used to determine the altitude of the North star?
The device used to determine the altitude of the North Star (Polaris) is called an astrolabe. An astrolabe is an ancient astronomical instrument that allows users to measure the angle of celestial objects above the horizon. By aligning the astrolabe with Polaris, one can determine their latitude based on the altitude of the star. This technique has been used for navigation and understanding one's position on Earth.
What is pleiades' alcyone?
The Pleiades are the seven daughters of Atlas and Pleione, of which Alcyone is numbered among them being the Pleiad star-nymph of Mount Kithairon in Boiotia (central Greece) loved by the god Poseidon.
