List of the smallest stars by star type. The red dwarf stars are considered the smallest stars known, and representative of the smallest star possible. Brown dwarfs are not massive enough to build up the pressure in the central regions to allow nuclear fusion of hydrogen into helium.
13 lut 2009 · OGLE-TR-122b is the smallest star with its radius accurately measured, only 167,000 km across. It has 100 times the mass of Jupiter and orbits a white dwarf star. Learn more about red dwarfs, the smallest stars around, and how they form and die.
EBLM J0555-57Ab, the smallest star in the system, orbits its primary star with a period of 7.8 days, and currently is the smallest known star with a mass sufficient to enable the fusion of hydrogen in its core.
In 2017, an international team of astronomers announced the discovery of a so-called red dwarf star that’s so small it barely functions as a star. Code-named EBLM J0555-57Ab and lying some 600 light-years away, it’s similar in size to the planet Saturn.
Red dwarfs are the smallest main sequence stars – just a fraction of the Sun’s size and mass. They’re also the coolest, and appear more orange in color than red. When a red dwarf produces helium via fusion in its core, the released energy brings material to the star’s surface, where it cools and sinks back down, taking along a fresh ...
G1623b is a ten times less massive star than the Sun, located 25 light years away in the constellation Hercules. It was first detected by astrometric observations and resolved by Hubble's faint object camera in 1994.
12 lip 2017 · A star about the size of Saturn, with a mass comparable to TRAPPIST-1, has been identified by a team of astronomers led by Cambridge. The star, called EBLM J0555-57Ab, is part of a binary system and was measured using the WASP and CORALIE experiments.
