b68Å

B68Å is a brown dwarf object located in the Pleiades star cluster, a group of young stars in the constellation of Taurus. It is classified as a brown dwarf due to its mass being below the threshold for sustaining nuclear fusion in its core.

B68Å was first observed in the 1980s as a red object with a low luminosity, but it was not until the 2000s that its nature as a brown dwarf was confirmed. Since then, it has been the subject of several studies aimed at understanding its properties and behavior.

One of the most interesting aspects of B68Å is its evolutionary stage. Brown dwarfs are thought to form in a similar way to stars, but they lack the mass necessary to sustain nuclear reactions in their cores. As a result, they cool and contract over time, ultimately reaching a state of complete non-emission by emitted light, known as stationary states, or the dim and cool final state.

B68Å's mass is estimated to be around 58 times that of Jupiter, and its temperature is known to be approximately 3,000 Kelvin. It is thought to be in the late stages of its evolution, near the end of its cooling process and outgoing into the state of stationary states. B68Å's size and surface area make it a good candidate for studying the atmospheric properties and the rise and fall of the cool final state.
