Astronomers using NASA's TESS have discovered a new Saturn-mass exoplanet, designated TOI-2447 b, orbiting a solar-type star. The planet has a radius of 0.86 Jupiter radii, a mass of 0.39 Jupiter masses, and an orbital period of 69.34 days. Additional evidence suggests the presence of more planets in the system, pending further observations.
Using ALMA, astronomers have discovered a large double-ring dust disk around the M-dwarf star 2MASS J04124068+2438157. The disk consists of two narrow rings at distances of 70 and 116 AU, with the outer ring being narrower than the local pressure scale height, suggesting the presence of a pressure bump that traps dust particles. The authors suggest that planet-disk interactions are the most likely explanation for the observed gaps and rings in the disk, with the properties of the gap between the two rings indicating the presence of a Saturn-mass planet at about 90 AU from the star. Further observations are required to confirm this assumption.
