Using ESO’s Very Large Telescope (VLT), an international team of astronomers has uncovered the presence of a low-mass stellar companion to a young variable star known as RZ Piscium. The newly detected object is about eight times less massive than the sun, and orbits the primary star at a distance of around 23 AU. The finding is reported in a paper published in Monthly Notices of the Royal Astronomical Society. A pre-publication version is available on arXiv.org.
