∙ 11y agoT 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.

Electra is a binary star system, consisting of two stars. The primary star, Electra A, is a blue-white giant star with a diameter estimated to be around 7 times that of our Sun. The secondary star, Electra B, is a white dwarf with a much smaller size, approximately the size of Earth.
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.
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.
Spectral class B stars are hot, with surface temperatures ranging from approximately 10,000 to 30,000 degrees Celsius. These stars emit large amounts of ultraviolet radiation due to their high temperatures.
Epsilon Tauri b was created in 2007.

Atlas, also known as 27 Tauri, is a binary star system in the Taurus constellation. The primary star, Atlas A, is a white giant star in the later stages of its life cycle. It is expected to evolve into a red giant before eventually shedding its outer layers to become a planetary nebula, leaving behind a white dwarf core. The exact timeline for this process is difficult to predict with precision, but it is estimated to occur within the next few million years.
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.
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.
B stars are between 10,000 -> 30,000 K whereas G stars (like our Sun) are between 5,200 -> 6,000 K

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.
