The astro-ph Reader’s Digest
Today we take a closer look at rare system that might just be host to an even rarer Cepheid.
The dark matter halos of galaxies and clusters of galaxies—objects of literally astrophysical dimensions—have lots to say about the mysterious, likely subatomic, dark matter particle.
Finding extraterrestrial intelligence would be one of the most enlightening and profound discoveries in history. Today’s post looks at two potential means of finding extraterrestrials by seeing their advanced technology elsewhere in the Milky Way and the Universe.
Astronomers have known for a while that GRBs are sign-posts to galaxies which are forming lots of stars. But today’s paper used radio observations of the gas to connect that star formation to a recent merger.
Extreme transient events are pushing the limits of our standard explosion models, but magnetars may save the day.
Last year, an image was released that took our breath away. Exquisite rings carved in a disk of material around a nearby star. Now, astronomers want to know if forming planets are responsible, and why the image might look different from the cartoon in your textbook.

Planets seem to occur all over the place in the universe. However, it is still unknown how they form. The growth of objects larger than meter size is difficult because objects of this size quickly fall into the central star. This Astrobite gives a small overview of the meter-size barrier as found by Stuart J. Weidenschilling in 1977.
Much of what we know today about exoplanets is due to the success of the radial velocity method. Where does it stand now? What is its future?
