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.

In the H-R diagram star A is to the right of the star B. which has the higher temperature?

Star A has a higher temperature than star B. In the H-R diagram, stars to the left are cooler and stars to the right are hotter.


What is the size of electra star?

I assume you mean 17 Tauri, one of the stars in the Pleaides cluster. The best information I can find is that it's about six times the radius of the Sun. Despite not being that much larger than the Sun, it's still a "giant" (not on the main sequence). Blue "dwarf" (main sequence) stars are actually not much smaller than the smallest blue "giant" stars, and the difference is determined spectroscopically rather than by size measurements.


Why are there no massive O and B stars?

Massive O and B stars have shorter lifespans due to their high rate of fusion and energy output, leading to a faster depletion of their nuclear fuel. As a result, they are relatively short-lived compared to lower mass stars. Additionally, massive stars have strong stellar winds and are more prone to exploding as supernovae, further limiting their presence in the universe.


Are any of the 20 nearest or 20 brightest stars white dwarf?

Yes, some of the 20 nearest stars are white dwarfs. For example, Sirius B, the companion star to Sirius A, is a white dwarf. Among the 20 brightest stars, Sirius B is the only white dwarf.


Is spectral class B in space hot or cold?

Spectral class is the categorization of stars by temperature and size, mostly the former. Spectral class B is very hot. In descending order (hottest to coolest) the spectral classes are O,B,A,F,G,K,M. You can see that B is very near the top.

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.

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.
