Chromospheric and photospheric activity in M dwarfs appear to be correlated, with stellar rotation influencing both types of activity and metallicity impacting the intensity of chromospheric activity.
By cross-matching results from two different search algorithms, researchers have discovered three new Milky Way satellites, two of which appear to be dwarf galaxies and one of which is likely a star cluster.
New observations of a young star cluster challenge the view that lithium depletion only occurs after 150 million years; the team also uncovered a correlation between stellar rotation rate and lithium depletion.
Combining data from Mariner 10 and MESSENGER, researchers find that space weathering processes mix graphite into the surface material in Mercury, which potentially alters the material’s phase.
Researchers analyze localization tools that may be used to pinpoint the sources of short gamma-ray bursts in light curves from the Anticoincidence Subsystem on the Compton Spectrometer and Imager (COSI).
Researchers lay out a path to finding Earth-sized moons around Jupiter-sized planets by detecting when the moon ducks behind the planet from our point of view.
