Chaos Among the Stars
Some variable stars seem to be “golden”, but is this property fundamental or just chance?
Direct Detection of Exomoons
There are more moons than planets in our Solar System that harbor liquid water, and these moons may offer us the best chances of finding life off of Earth. Today’s paper takes the search for habitable moons a step further by investigating how telescopes of the near future might allow us to see and characterize these moons around exoplanets.
Feeding on the Cosmic Web
Observations of dwarf galaxies show that sites of active star formation have fewer metals. These galaxies may have been diluted by the impact of pristine gas from the cosmic web.
Searching for white dwarf companions around millisecond pulsars
Images from the Hubble Space Telescope show that there are previously unknown white dwarfs orbiting around pulsar companions.
Starspots to Measure Small Differential Rotation Rates
On using photometric data from Kepler to study starspots, and to measure differential rotation rates.
A Cepheid Anomaly
Today we take a closer look at rare system that might just be host to an even rarer Cepheid.
