Overcoming Small Sources of Noise to Help Reveal Small Planets
Today’s paper creates a new model for predicting the RV scatter from convective blueshift and helps reveal the challenges of finding small exoplanets
A New Recipe for Neutron Star Magnetic Fields
How do neutron stars acquire such strong magnetic fields? Why do these fields differ between pulsars and magnetars? Today’s paper suggests that *convective dynamos* may be at play.
Mind the (Gaia) Gap
Today’s authors find a strange feature in the main sequence of the Gaia HR Diagram. Read to see what this says about M stars!
The Tortoise and the Star
Spectrographs here on Earth are getting good enough to detect tortoise-speed velocity shifts in starlight. That means that we need to understand the bubbling, broiling surfaces of stars to tortoise-level precision.
A Naked-Eye Superflare Detected from Proxima Centauri
The Sun’s closest neighbor star Proxima Centauri—normally invisible to the naked eye—may have briefly become visible by increasing in brightness over 100 times for a few minutes back in 2016 in the largest flare ever seen from it.
On the Insides of Giants: Heat Transfer in Hot-Start, Core-Accreting Gas Giants
Thick clouds shroud the interiors of gas giants, like Jupiter, in mystery. Today’s authors set out to blow some of that mystery away. Using equations and modeling, they explore processes of heat transfer within the interiors of hot-start, core-accreting gas giants.
