Illustration of a FBOT. In astronomy, a fast blue optical transient (FBOT), or more specifically, luminous fast blue optical transient (LFBOT), is an explosive transient event similar to supernovae and gamma-ray bursts with high optical luminosity, rapid evolution, and predominantly blue emission. [1]
Luminous blue variable stars can undergo "giant outbursts" with dramatically increased mass loss and luminosity. η Carinae is the prototypical example, [20] with P Cygni showing one or more similar outbursts 300–400 years ago, [21] but dozens have now been catalogued in external galaxies.
Other sunburst varieties over the years included "Sienna Sunburst" and "Blue Burst", first introduced by Harmon in the late '70s and mid '80s. The American Series Strat HSS and the Strat Plus guitars are examples. The British Burns company use greenburst finishes on a number of their guitars, such as the Steer and Scorpion. [1]
Commonly known as magic blue, it is the hexachloroantimonate salt of an amine radical cation. It is a blue solid that reacts with many solvents but is soluble in acetonitrile . The compound is a popular oxidizing agent in organic and organometallic chemistry , with a reduction potential of 0.67 V versus ferrocene /ferrocenium ( acetonitrile ...
Blue light is absorbed by the structural proteins, enzymes, and protein metabolites found in the lens. [9] The absorption of blue light creates yellow pigments in the lens's protein. The lens progressively darkens and turns yellow. [9] Blue light is absorbed by the lens, preventing blue light from reaching the retina at the back of the eye. [12]
Simultaneously, a burst of electrical pulses is applied to the muscle at the beginning of each shortening-lengthening cycle to stimulate the muscle to produce force. Since force and length return to their initial values at the end of each cycle, a plot of force vs. length yields a 'work loop'.
"I don't know what the future holds, but to the parents who are just hearing 'Mom, Dad, I'm trans,' know that this is only the first phase of your journey."
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
