High-resolution spectra of 35 nearby K dwarfs have been obtained and analyzed as part of an effort that will ultimately survey thousands of K dwarfs in the solar neighborhood.
Researchers explore the depletion of nitrogen, an important but little-studied component of protoplanetary disks, and discover that it is mainly lost in the gas phase through the vertical cold finger effect.
Models indicate that soil deposits on Saturn’s moon Titan are correlated with factors such as average precipitation and elevation, allowing researchers to predict the extent of these features in not-yet-imaged regions.
Researchers calculate the energies and temperatures of icy dust grains in the interstellar medium after these grains have been irradiated by cosmic rays, providing a useful input for astrochemical models.
The deformation of a coronal mass ejection — a huge, sudden release of plasma from the Sun’s upper atmosphere — may explain why these events do not always arrive at the expected time.
A reanalysis of an exoplanetary system containing two giant planets within the host star’s habitable zone indicates that the planets are not in a truly resonant state as previously thought.
