Flare stars

These are used as illuminant and they hang from a parachute. Increasing population density and urbanization mean that parachute flares are going to be gradually phased out for safety. They can still however be used at sea, on lakes, in the desert or in a district where there is no danger of fire. 

The barium light uses the BaO spectrum and the sodium lights, I and II, use the strong spectrum spreading on both sides of the NaD lines. The burning data are shown as a summarized standard in the case of flares loaded at a high pressure. The barium light produces a white flame. 

The optimum burning range with few sparks or cinders is limited from 45 to 55% magnesium. The sodium light is larger than that of the barium light. 

Sodium nitrate has not been used in Japan up to now due to its hygroscopic nature, but material which is well purified is hardly hygroscopic, and is extensively used in Europe.

Like many red dwarfs, Proxima or Alpha Centauri C is a flare star. Flare stars can brighten suddenly to many times their normal luminosity. The cause is thought to be a sudden and intense outburst of radiation on or above the star s surface. An increase in radio emission is often detected simultaneously with the optical outburst. 

Uses As oxidizing agent in primer caps in combination with mercury fulminate and with red phosphorus, antimony sulfide, and other combustible substances,1 P36. In pyrotechnic mixtures as component of airplane flares, stars for aerial bombs and for signaling, maroons, white and colored smokes. As component of Permissibles. In incendiary projectiles, P5. 

Uses General priming for flares, stars, gerbs and fuse.

Flares, Signaling Devices, and other Pyrotechnics. A large number of formulations contg K perchlorate have been reported. Some devices which use these are red RR signal flares (Refs 2 22, p 275) parachute flares (Ref 6) stars for use in signaling pistols (Very pistols) (Refs 5. 22, p 275) variously colored flares (Refs 19, pp 197-8 22, p 275) stars and other components of display fireworks (Refs 16 32) ... 

Alternatively, 6Li in low-metallicity stars could be the result ol 4Hc(3Hc, p) reactions in stellar flares, analogous to effects found in some energetic solar flares (Tatischeff Thibaud 2007). In this case there is expected to be real scatter in the 6Li plateau, due to variations in (present or past) stellar rotation speed. 

Exceptionally violent phenomena can nevertheless disturb this fine order. Some of them bring tremendous speeds into play, in both translational and rotational motions. Solar and stellar flares come to mind, along with exploding stars and spinning pulsars (neutron stars). If part of this well-ordered energy is conferred upon an atomic nucleus, it then becomes a cosmic ray. It is thus excluded from the community, whose gentle brethren are no longer able to retain it. 

The solar atmosphere is too cool to lead to helium excitation, and hence helium lines, except in exceptional conditions associated with flares. The helium content of the Sun is therefore inferred from observations of hotter stars. 

Detonation (and Explosion) in Media of Variable Density. The study of this topic was conducted by some Rus scientists because it was considered that the problem has an application on the cosmic scale such as in explosions (evidenced by flare-ups) of novae and supernovae stars...

The accretion flow with this instability will produce strong accretion shocks, turbulence, and heating of the outer layer of the star. Matter will also be ejected, and this could account for much of the mass and energy from young stars. The luminous FU Ori flare-ups may be important energy source for driving molecular out flows around low mass young stars.

Colored light compositions are used in the form of a loose powder, or are tamped into paper tubes in torches for political parades, for highway warnings, and for railway and marine signals, in Bengal lights, in airplane flares, and in lances for set pieces, or are prepared in the form of compact pellets as stars for Roman candles, rockets, and aerial bombs, or as stars to be shot from a special pistol for signaling.
