Identifying the sculptor: what dynamical processes lead to observed planet multiplicity
The Kepler dataset appears to be split between single planet systems and multi-planet systems. Could this be because systems become dynamically hot over time?
Johannes Kepler and the Case of the Disappearing Sunspots
Today’s paper uses Johannes Kepler’s pre-telescope sunspot drawings to re-examine irregular 17th century solar activity.
The Case of Shrinking Planets
The authors of today’s papers investigate whether photoevaporation or core-powered mass loss is the more likely culprit for the exoplanet radius gap.
Orbital Teasing: Planetary siblings pick on each other with TTVs
Does your sibling know how to push your buttons? Turns out exoplanets also mess with each other. This “teasing” can be used to learn about their character(istics)!
