Exoplanetary Scratchpad

[SysBP Img]

Star 140 ly away with possibly the first planet found with rings. The star is similar in size to the Sun, but much younger, at 16 MYO. The planet's transit fluctuated unusually, pointing to a ring system of four defined rings that extends 60 MKm from the planet, with a mass of eight times Earth's moon. 95% of the light was blocked during the thickest transit of the rings. Moons could be forming in this ring system. The inner solar system could have looked like this in its first 10s of Millions of years. Might be a brown dwarf or low mass red dwarf with a planetary disk instead. Further radial velocity measurements will be needed to confirm its mass and nature.
