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
Siblings or Only Child: M Dwarf Planets
M dwarf stars host single planet systems (only child) and multi-planet systems (siblings). Let’s explore the differences!
Astronomers Join Forces Against The Sun
Our own Sun holds the keys to our understanding of how stellar activity signals present in radial velocity data sets. Now four international spectrograph teams have joined forces to combine data.
Where’s the Edge of a Planetary System?
Many exoplanet systems are found to contain similar sized planets at evenly spaced orbits within the system. Where does this pattern end? And could it be due to a Jupiter like planet at the outer reaches of the system?
Do Small Stars Have Big Planets? No.
The most common type of star in the universe, the M dwarf, seems to be lacking any Jupiter-sized exoplanets. Why is that?
