Astro Data Hack Week

This wasn’t a week of watching; it was a week of doing.

Hide and Seek Planets

Is CoRoT-7d real, or is it stellar activity masquerading as a planet? Haywood et al. build a noise model to analyze CoRoT-7′s activity to find out.

Beyond Chi-Squared: An Introduction to Correlated Noise

A common measure of the quality of a fit is the chi-squared statistic. While common, implementation of this statistic assumes uncorrelated noise, which is much less common. Today, we discuss how to deal with noise that is correlated and why it’s important.

A Planet for Every M Dwarf Star?

A recent result on the commonality of exoplanets has made headlines, but has it for the right reasons?

A Fast Radio Burst From Close to Home?

Astronomers are hearing a new type of radio transient, but no one knows where they come from and how they are created. This paper suggests one of the six documented Fast Radio Bursts detected so far originated close to home, within our own galaxy.

Pinpointing Stellar Properties with Bayesian Statistics

The link between a pile of data and a physical explanation is the fun part. Astronomers spend countless hours gathering data, and countless more thinking up physical models for different pieces of the Universe. But reconciling these two things—finding a model that not only agrees with observations, but is the sole likely explanation—isn’t easy.

Adventures in Astrostatistics: Astrobites at SAMSI (Part 2/2)

Part two of our recap of the “Modern Statistical and Computational Methods for Analysis of Kepler Data” workshop in North Carolina, featuring both astronomers and statisticians!

Gaia: The New Kepler?

There’s a new space telescope on the block, which just might find as many new planet candidates as the Kepler mission.

Recap of the IAU Planet Formation Symposium

Highlights from the International Astronomical Union Symposium on “Exploring the Formation and Evolution of Planetary Systems”.
