How do clusters of O and B stars compare to clusters of T Tauri stars?
Wiki User
∙ 11y ago
T Tauri stars are pre-Main Sequence stars which are large but not as hot as O and B Main Sequence stars. They mainly fall in the categories of F, G, K or M, and they are not yet on the Main Sequence because they are still accreting mass and are still very young and unstable.

Why are there no massive O and B stars?
There are stars with spectral classes of O & B (e.g. Rigel) R136a1 is a star of the spectral class WN5h. Wolf Rayet stars have this kind of spectral type.
What are the all examples of star?
Most stars are currently classified using the letters O, B, A, F, G, K, and MAccording to informal tradition, O stars are called "blue", B "blue-white", A stars "white", Fstars "yellow-white", G stars "yellow", K stars "orange", and M stars "red", even though the actual star colors perceived by an observer may deviate from these colors depending on visual conditions and individual stars observed.
What are the brightest bluest stars?
stars in spectral classes O, B, or A would be a bright bluish color, leaning towards a purplish color as you go from A to O.
What are the stars with a mass 1.5 times greater than the sun?
Spectral types O, B and A.
What do halo stars do differently from disk stars?
I assume, that a) by Halo stars, you mean high velocity stars, and b) by disk stars, you mean stars that stay within the galaxy (Normal stars).Halo stars are usually very old stars that do no orbit the centre of the Galaxy the same way that our Sun or other stars in a galaxy. Rather, they travel in elliptical orbits, which often take them well outside the plane of the Galaxy.
When was Epsilon Tauri b created?
Epsilon Tauri b was created in 2007.

When Will Atlas The Star Die?
Atlas, also known as 27 Tauri, is a triple star system in the Pleiades open cluster (M45).These three stars are known as - Atlas A, B and C.However to determine the age of a star, the mass and luminosity is required, and to date, this information is not available.
How do the clusters work in Boston latin school?
They're usually categorized by the instruments you take. If you didn't sign up for any then I guess you are randomly put in. You get clusters from 7th to 8th. There are only three clusters, A,B, & C.
Compare the characteristic of stars based on size?
The classes of stars, from hottest to coolest is O,B,A,F,G,K,M. You can remember that with this mnemonic: "Oh, Be A Fine Girl, Kiss Me!" Follow the link below to see what it means.
Are b stars hotter than g stars?
B stars are between 10,000 -> 30,000 K whereas G stars (like our Sun) are between 5,200 -> 6,000 K

What are the uses of ratio's?
With probability ratios the value you get to describe the strength of the relationship when you compare (A given B) to (A given not B) is not the same as what you get when you compare (not A given B) to (not A given not B). This is, IMHO, a big problem. There is no such problem with odds ratios.
