New Evidence of an Asteroid Encountering a Pulsar

Title: Evidence of an Asteroid Encountering a Pulsar Authors: P. R. Brook, A. Karastergiou, S. Buchner, S. J. Roberts, M. J. Keith, S. Johnson, R. M. Shannon First Author’s Institution:  University of Oxford Pulsars- neutron stars formed during supernovae explosions- are often considered the “precision clocks” of radio astronomy. This is because of two fundamental properties observed from […]

Unveiling the friend of a pulsar

What kind of star is orbiting around a millisecond pulsar and where did it come from?

An Astronomical (Anti-)Glitch

The authors of this article observe a sudden slowing in the rotation rate of a known magnetar. Although hundreds of glitches (a sudden increase in rotation rate) have been observed in radio pulsars and magnetars, this is the first direct evidence for an anti-glitch.

A Universal Clock Skewed by … Asteroids?

We’ve detected planets around pulsars before, but this pulsar has an even stranger signal. Could it be due to an asteroid belt similar to the one in our solar system orbiting it?

UR #5: Isolated Neutron Stars and Galaxy Evolution

This month’s undergrad research post is all about X-rays. Read on to learn more about studying the X-ray counterpart to a radio pulsar, and examining the evolution of galaxies using X-ray emission.
