Unveiling the friend of a pulsar
What kind of star is orbiting around a millisecond pulsar and where did it come from?
Using General Relativity to Measure Properties of Binary Pulsars
Shapiro time delays are one of the four tests of general relativity possible in the solar system. Astronomers can use these timing delays to measure properties of binary pulsar systems.
Checking Out Our New Neighbors
A new brown dwarf system has been discovered only 2 parsec away; Gillon et al. analyze its light curve to study clouds on the surfaces of these stars.
Exploding diamonds in the sky
Pakmor et al. propose a new mechanism to make Type 1a supernova explosions from a pair of white dwarfs.
Three’s a Crowd: Potential Triple-Star Systems in the Kepler Field
By looking for variations in the observed periods for eclipsing binary stars, astronomers have found evidence that a sizable fraction of these systems are actually systems of three or more stars.
When Push Comes to Shove: How Wide Binaries Can Wreak Havoc on Planetary Systems
New simulations show that — due to forces from outside the stellar system — wide stellar binaries may disrupt planets much more than previously thought.
