Planets with radii between Earth and Neptune and small radii are the most common in planetary systems. These planets are challenging to explain with classical models of planets. Do planets form instead in-situ in an inside-out manner?
Spirou often runs into fantastic adventures with his courageous, and sharp pet squirrel Spip. Their next adventure: a radial velocity spectrograph. What sophisticated technology is this? How does it work? What can it help us find?
Some variable stars seem to be “golden”, but is this property fundamental or just chance?
Astronomy & astrophysics is certainly an exciting field of research, but imagine there is a lot of research in other fields as well. How has research across different disciplines evolved in the past and how will astrophysics & astronomy do in terms of interdisciplinarity in the future?
On using photometric data from Kepler to study starspots, and to measure differential rotation rates.
Do you own a digital single-lens reflex (DSLR) camera? The authors of today’s paper do. They used it for astronomy. They used it for science.
