The Jeans mass is named after the British physicist Sir James Jeans, who considered the process of gravitational collapse within a gaseous cloud. He was able to show that, under appropriate conditions, a cloud, or part of one, would become unstable and begin to collapse when it lacked sufficient gaseous pressure support to balance the force of gravity.
Sir James Hopwood Jeans OM FRS [1] (11 September 1877 – 16 September 1946 [2]) was an English physicist, mathematician and an astronomer.He served as a secretary of the Royal Society from 1919 to 1929, and was the president of the Royal Astronomical Society from 1925 to 1927, and won its Gold Medal.
Jeans Equation simulations place limits on the size of this halo. An example of such an analysis is given by the constraints that can be placed on the dark matter halo within the Milky Way. Using Sloan Digital Sky Survey measurements of our Galaxy, researchers were able to simulate the dark matter halo distribution using Jeans equations. [8]
Serena Williams is ending 2024 by celebrating a big milestone.. The tennis champ, 43, has been documenting her weight loss journey on Instagram after giving birth to her second daughter, Adira ...
In most of the photos, she's wearing baggy jeans, but one image in particular stood out to her followers. In the photo, EmRata, as she's affectionately known, stands in a pair of light-wash jeans ...
The square root of the ratio is about 6. I dislike the formula here as it makes Jeans Mass for Bernard 68, 10.117 solar masses and Cambridge's formula makes Jeans Mass 1.662 solar masses assuming it is all molecular hydrogen not just mostly. Anyway, it is advertised in Wikipedia as a collapsing cloud a star that will be born in 200,000 years.
