How do so many hot jupiters come to orbit backwards?
Depending on how they scatter with nuclei, dark matter particles might affect the structure and evolution of our Sun.
Field lines are a powerful tool for building intuition for a complex geometric object.
Dust traps may be the key to forming Kepler-16b and other circumbinary planets.
A relatively detailed discussion of a classic paper in cosmology, which basically covers everything you might want to know about how structure forms in the Universe on the very largest scales.
Measurements of the circular velocities in groups of galaxies can test whether our current cosmology is correct.
The mass of the cores of giant planets affects their luminosity after formation, complicating how we determine the mass of directly imaged planets.
The authors of today’s paper investigate the feeding habits of the elusive quiescent supermassive black hole, finding that in addition to swallowing some stars whole and constantly snacking on the winds of other stars, some black holes may also dine on giant stars slowly disrupted over tens to hundreds of orbits.
Highlights from the International Astronomical Union Symposium on “Exploring the Formation and Evolution of Planetary Systems”.
Detailed atmospheric models reveal that planets can be habitable much closer to their host star than previously thought, provided they have desert-like climates. This expanded definition of the habitable zone increases the number of planets that could support life by a factor of 2-3.
