Red dwarf star
Red dwarf star. Artwork representing the intense activity of a red dwarf star. These are among the least massive stars in the universe ranging from 0.1 to 0.7 solar masses. The star shown here belongs to a subclass of red dwarf stars, known as the flare stars, which are characterised by frequent (3-4 per hour) flares. These are seen as sudden brightenings with a typical rising time between 1s and 1min and a slower fading time between 1min and 1 hour. During a flare, filaments of gas in the atmosphere are accelerated outwards with speeds up to 1000km/s. Such speeds are greater than the escape velocity and therefore the matter ejected will be lost from the parent star

EDITORS COMMENTS
This artwork showcases the intense activity of a red dwarf star, one of the smallest and least massive stars in the universe. With its vibrant hues of red, it mesmerizes viewers with its peculiar nature. Belonging to a subclass known as flare stars, this particular red dwarf is characterized by frequent flares occurring at an astonishing rate of 3-4 per hour. During these flares, sudden bursts of brightness illuminate the star's atmosphere, creating a spectacle that lasts anywhere between 1 second and 1 minute. As if defying gravity itself, filaments of gas are propelled outward at mind-boggling speeds reaching up to 1000 kilometers per second. Such velocities exceed the escape velocity, causing these ejected materials to be lost from their parent star forever. In this stunning depiction crafted by Science Photo Library, we witness not only the beauty but also the volatile nature inherent in celestial bodies like red dwarfs. This artwork serves as a testament to humanity's fascination with stellar astronomy and our relentless pursuit to unravel the mysteries hidden within outer space.
