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”.

Transit Probabilities: Not As Simple As They Seem

Our simple formula for predicting the probability that an exoplanet will transit might miss something important.

The Frequency of (Habitable?) Planets Around M dwarfs

The census of planets for smaller stars—M dwarfs—is now basically complete. In this paper, Courtney Dressing and Dave Charbonneau use this M dwarf advantage to determine the occurrence rate of small planets around M dwarfs.

Sgr A*: A flickering black hole

Witzel et. al examine the statistical properties of the photometric variability of our Galaxy’s central black hole.
