Today a rather big paper dropped. The paper lists a number of planets, as well as making its own discoveries and determining false positives.
Most notable of them are a new, potentially Neptune or Saturn-like planet at Lalande 21185, and the confirmation of one planet around Lambda Serpentis and 14 Herculis each.
Lalande 21185 c
Semi-major axis: 3.1 AU
Orbital period: 8.73 years
Eccentricity: 0.14
Minimum mass: 18.0 Earth masses
Lambda Serpentis b
Semi-major axis: 0.1238 AU
Orbital period: 15.5083 days
Eccentricity: 0.16
Minimum mass: 13.6 Earth masses
Several planets have been determined as false positives, including 61 Virginis d, known in Orion's Arm as Iolus. That planet was kind of in the way of Eostremonath, so this might be a good news if it means we can replace it with a smaller planet with more circular orbit.
