The Jeans instability is a concept in astrophysics that describes an instability that leads to the gravitational collapse of a cloud of gas or dust. [1] It causes the collapse of interstellar gas clouds and subsequent star formation. It occurs when the internal gas pressure is not strong enough to prevent the gravitational collapse of a region ...
Gravitational collapse of a massive star, resulting in a Type II supernova. Gravitational collapse is the contraction of an astronomical object due to the influence of its own gravity, which tends to draw matter inward toward the center of gravity. [1] Gravitational collapse is a fundamental mechanism for structure formation in the universe.
December 14, 1940 - A tank farm fire I Texas City killed one person, and injured 18 others. [156] May 16, 1952 - A massive tank farm fire hit a Corpus Christi terminal. [155] April 11, 1965 - A gas well blew out in Parker County, causing a massive fire. Firefighter Red Adair had to be called in to control the well, which was capped on April 17 ...
“Gas explosions are trending upward generally across the country. I think it’s an increasing problem and more and more people are being injured and killed in gas explosions,” Hageman said.
The most basic gravitational stability analysis is the Jeans criteria, which addresses the balance between self-gravity and thermal pressure in a gas. In terms of the two above stability conditions, the system is stable if: i) thermal pressure balances the force of gravity, and ii) if the system is compressed slightly, the outward pressure ...
Early estimates indicate up to 2,000 gallons of oil may have spilled into surrounding waters when a barge carrying fuel broke free from a tugboat and slammed into a bridge near Galveston, Texas ...
The Oppenheimer–Snyder model of continued gravitational collapse is described by the line element [13] = + (+ +) The quantities appearing in this expression are as follows: The coordinates are ( τ , R , θ , ϕ ) {\displaystyle (\tau ,R,\theta ,\phi )} where θ , ϕ {\displaystyle \theta ,\phi } are coordinates for the 2-sphere.
[8] [9] The roof of the tank was designed to collapse in the event of an explosion. [5] TETCo officials had been "fanatical about safety", [ 4 ] and even on the day before the explosion, February 9, 1973, TETCo officials called Staten Island residents "hysterical" for raising concerns about the danger of storing gas near residential areas.
