Seeing Red (and Blue): Two Sub-Populations of Type Ia Supernovae?
A close examination of thirteen Type Ia supernovae in the earliest days after their initial explosion reveals two distinct sub-populations.
The loudest planets in our sky: gravitational waves from Super-Jupiters
Nearby Super-Jupiters with very tight orbits produce gravitational waves that will be detectable by space-based gravitational wave detectors.
More Informative Mapping of Exoplanetary Peekaboos
Mapping the atmospheres and surfaces of exoplanets is ailed by degeneracies due to the choice of map structure and orbital parameter uncertainties. Today’s paper attempts to solve this by using a principal component analysis approach.
Cool Stars 20
This week about 500 astronomers met in Boston, MA for the 20th Cambridge Workshop on Cool stars, Stellar Systems, and the Sun (Cool Stars) meeting.
What happened to the Milky Way’s sister galaxy?
Cosmic cannibalism, or the merging of small galaxies with larger ones, happens all over the universe. We now know that the Milky Way lost a sister galaxy to Andromeda, and we’re now a step closer to understanding what might ultimately happen when Andromeda comes for us.
The Jupiter Analog Companions to Super-Earths
Today’s authors search for Jupiter analogs in foreign star systems to see how these giant worlds might affect the development of planets closer to the sun.

Astrobites at ASA: Astronomy Down Under!
The annual meeting of the Astronomical Society of Australia happened last week; here’s a short summary of some of the incredible science happening Down Under!
SPIE From the Perspective of a Non-Instrumentalist
Continuing on the thread from Friday’s post, I also attended the recent SPIE meeting. Here are my thoughts, as someone who is on the science side of the field, on the engineering and instrumentation conference.

Meet the AAS Keynote Speakers: Julie Comerford
Some galaxies live peaceful lives, calmly making stars at a sedate pace, with supermassive black holes that don’t vomit jets of material. Other galaxies… not so much. Come to Professor Julie Comerford’s upcoming #AAS232 talk to learn more about the weird and wonderful world of active galactic nuclei!
Meet the AAS Keynote Speakers: Sarbani Basu
Hear about the work of Dr. Sarbani Basu in astroseismology and what to expect from her talk this Wednesday at AAS.
Meet the AAS Keynote Speakers: Keivan Stassun
Astronomy and exoplanet science are entering into an era of unprecedented precision. Check out Dr. Keivan Stassun’s plenary talk at #AAS232 to learn more!
