Red dwarfs and brown dwarfs exhibit two main forms of variability : they could be BY Draconis variables or flare stars, or both.
32.
Flare stars can increase in brightness by a few magnitudes in just a few minutes, and fade to normal in a few hours.
33.
It is a flare star, emitting unpredictable outbursts of energy for mere minutes, which might be much more powerful analogues of solar flares.
34.
Wolf 359 is a red dwarf of magnitude 13.5; it periodically brightens by one magnitude or less because it is a flare star.
35.
It is common only among the flare stars, also known as the UV Ceti variables, very faint main-sequence stars which undergo regular flares.
36.
In 1969, a brief flare in the luminosity of Wolf 359 was observed, linking it to the class of variable stars known as flare stars.
37.
From 1984 he was actively engaged in the search for quasi-periodic ultraviolet and infrared variations in flare stars indicative of active regions and stellar rotation.
38.
AD Leonis is a main sequence star with a spectral classification of M3.5V . It is a flare star that undergoes random increases in luminosity.
39.
It is a flare star that can emit powerful flares potentially visible to the naked eye, thousands of times more energetic than any from Earth's sun.
40.
His master's degree is from the University of Toledo, based on studies he did at Kitt Peak Observatory of eruptive and flare stars among red dwarfs.
