EBLM J0555-57
EBLM J0555-57 is a Star system#Triple star systems, triple star system approximately 670 light-years from Earth. EBLM J0555-57Ab, the smallest star in the system, orbits its primary star with a period of 7.8 days, and at the time of discovery, was the smallest known star with a mass sufficient to enable the Proton–proton chain reaction, fusion of hydrogen in its core. System EBLM J0555-57, also known as CD−57 1311, is a triple star system in the constellation Pictor, which contains a visual binary system consisting of two sun-like stars separated by 2.5": EBLM J0555-57Aa, a magnitude 9.98 spectral type F8 star, and EBLM J0555-57B, a magnitude 10.76 star. No orbital motion has been detected but they have almost identical radial velocities and are assumed to be gravitationally bound. Component A of the system is itself an Binary star#Eclipsing binaries, eclipsing binary (EBLM J0555-57Ab orbiting EBLM J0555-57Aa). Eclipses, also known as Transit (astronomy), tra ...
