If we know a star’s rotation we can calculate its age. But what happens if this rotation is affected by a nearby massive planet? And how much will this change our age estimate?
Moons of exoplanets have not yet been conclusively. Today’s authors carefully re-evaluate some of the evidence for their own candidate detection of the first known exomoon.
The Sun is known to rotate differentially, which plays a large part in our understanding of solar physics. Do we see the same differential rotation in Solar analogues, 16 Cyg A & B?
A new technique allows for precise measurements of the brightest stars observed by the Kepler and K2 missions. For its debut, the authors looked at the Pleiades Cluster.
