... from their emission spectra taken with ALMA, suggest that the planets in the system are larger than Jupiter. "This is the very first time that a multi-planet system with orbiting dust is imaged, allowing for direct comparison with...
...in the processed data. During their search, the team identified 747 unique planet candidates and 57 multi-planet systems. Of these candidates, 366 have not been previously identified, they say. “Discovering hundreds of new exoplanets is a significant...
... orbiting their host star. It also begged the question, if we could find one system like this, could we find anymore? Finding large multi-planet systems is rather difficult. It requires stable, high-precision Doppler (radial-velocity) monitoring and...
... and Neptune-mass exoplanets analysed data from 8 multi-planet systems to discover; one 4-planet system around HD 20781, two 3-planet systems around HD 31527 and HD 136352, and five 2-planet systems around HD 20003, HD 21693, HD 45184, HD 51608, and...
...as multi-star systems, should no longer be discounted. "Our best candidate for hosting a world that is potentially habitable is the binary system Kepler-38, approximately 3970 light years from Earth, and known to contain a Neptune-sized planet," says...
