Planet orbiting a brown dwarf or a brown dwarf binary? Astronomers use cosmic lens to find new substellar system

On: April 9, 2018

Using gravitational microlensing technique, an international group of astronomers has found a new substellar system whose composition remains a puzzle. The newly detected system, designated MOA-2015-BLG-337L, may consists of a planet orbiting a low-mass brown dwarf or may be composed of two brown dwarfs. The finding is detailed April 3 in a paper published on arXiv.org.
