The Impossible Star

KIC 2856960 appeared to be an interesting but straightforward triple star system in the Kepler catalog. But attempts to model this system prove that appearances can be deceiving.

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.

Most 1.6 Earth-radius planets are not rocky

Artist’s impressions of exoplanets are often wrong!

Nine Earth-like planets

There are nine Earth-like planets detectable in the Kepler data set… better get searching!

Kepler-10c: A Huge Rocky Exoplanet

According to planet formation theory, gas giants are more massive than rocky, terrestrial planets. But Kepler-10c is the size of Neptune, and denser than the Earth! Read on to find out more about the discovery of a new class of planets.

A super-precise super-Earth: measuring a planet’s radius to within 120 km

Kepler-93b is a super-Earth with a radius of 1.481 Earth radii, plus or minus Long Island.

Albedos of Super Earths

This paper introduces a new method of searching for occultations in Kepler data to study the albedos of close in super-Earths.

Testing the Titius-Bode law on exoplanets

From examining extrasolar planetary systems, we can test if the Titius-Bode “law” is actually a law.

Exomoons disguised as aliens

Exoplanets with moons could mimic alien life-signs.

Binary Hunting with Phase Variations

How do pulsating stars give away their secret identities as binary dance partners? In this paper, the authors demonstrate a new way to not only detect binaries we may have missed in the Kepler data, but also to measure their velocities without spectra.
