Are There Age Spreads in Intermediate Age Clusters?

Can stellar clusters be host to multiple star formation events? The authors of today’s paper take a closer look…

Trending Exoplanets

Are more massive stars more likely to have planets? Read on to find out…

Asteroseismic Spin Drs

If you didn’t know already, asteroseismology is awesome. Read on to hear why…

Making Order Out of Chaos

On Earth, the chaotic nature of weather leads to the famous “butterfly effect”, in which the flapping of a butterfly’s wings can theoretically create a hurricane. Chaos is a fundamental element of nature which can arise in many environments–including stars.

Real-Time Stellar Evolution

Sometimes, stellar evolution happens on more human timescales—tens to hundreds of years rather than millions or billions.

Mind the Gaps

Astronomical data gathered over time has gaps. Even the most reliable space telescopes suffer from occasional pauses in their otherwise constant watchfulness. Why are gaps a problem? Can’t astronomers just analyze the short chunks of data that don’t have gaps? The answer: Fourier transforms.

Spinning pair-instability supernovae

How does a massive star’s rotation affect the properties of its eventual explosion?

Three Stars in a High-Energy Dance

Stars: steady-burning nuclear flames that pierce the darkness of space. Except when they’re not. The star known as HD 181068 is bright, but it’s no standard candle. On closer inspection, this well-studied system is actually home to three stars locked in a complex cosmic dance.

What’s in a Heartbeat?

Instead of happily orbiting in circles with constant velocity, the two stars spend most of their time far apart, and a few harrowing hours racing past each other. Or, to put it another way: hours and hours of boredom punctuated by moments of sheer terror. This is a heartbeat star.

Peeling apart a neutron star

Neutron stars can provide insights into extreme and exotic states of matter.
