What else can I help you with?
If all the main sequence stars of a star cluster are typically only one hundredth as bright as their main sequence counterparts in the Hyades Cluster than the cluster's distance?
can be estimated by comparing their apparent magnitudes. Since brightness decreases with the square of the distance from an observer, a star cluster with main sequence stars one hundredth as bright as the Hyades Cluster would be approximately ten times further away from Earth than the Hyades Cluster.
What are the two stars that are not in the main sequence?
There are billions of stars that are not on the main sequence.
What are the stars in the main sequence?
The smallest stars in the main sequence are the stars with cooler surface temperatures.
The H-R diagram of a young star cluster shows?
The H-R diagram of a young star cluster shows a main sequence stretching from upper left to lower right, where stars are fusing hydrogen in their cores. It also may include some young, pre-main sequence stars located above and to the right of the main sequence, which are still contracting and heating up. Additionally, there might be some high-mass, short-lived stars in the upper region of the diagram, and low-mass, long-lived stars in the lower region.
Is most stars sequence stars?
"main sequence" is the tern.
What kind of stars are 90 of all Stars?
main sequence stars , our sun is also a main sequence star
Do red main sequence stars have the highest surface temperature?
No. They have the lowest temperatures on the main sequence. The hottest main sequence stars are blue.
Are there main sequence stars in the Milky Way?
Main sequence stars are found in all galaxies.
What is a diagonal band of stars on the H-R diagram?
Main sequence stars.
What most stars are classified as?
Main Sequence
Which color is the main sequence star is the most massive?
The most massive main sequence stars are typically blue in color. These stars are classified as O-type stars, characterized by their high temperatures and luminosities. Their intense heat causes them to emit light primarily in the blue and ultraviolet spectrum. Examples include stars like Zeta Ophiuchi and the stars in the Pleiades cluster.
About 90 of all stars are what kinds of stars?
About 90% of all stars are main sequence stars, including our Sun. These stars are in the stable phase of their lifecycle, where they fuse hydrogen into helium in their cores. Main sequence stars are the most common type of stars found in the universe.
