Supernovae Cribs
Today’s paper explores the galactic homes of superluminous supernovae — some of the brightest explosions in our universe.
My cousin is out finding exoplanets, and what do I get? Stellar activity
In 2014, astronomers found evidence for the existence of two super-Earths orbiting the 10 billion years-old Kapteyn’s star. However, today’s paper is casting doubt on the detection of at least one of these planets, and stellar activity is to blame.
Observational Evidence for the First Generation of Stars
Have we found evidence for the first generation of stars? This paper details observations made of CR7, one of the brightest observed high redshift galaxies
The ‘Ultimate’ X-ray Sky Survey: Finding Active Galaxies in Superclusters
The XXL Survey is here as the rightful successor to the XMM-Newton survey that gave us a unique and extravagant look into the high-energy universe. Here, we look at some of the observations that the XXL has to offer!
An Overview of the Extreme Solar Systems III Conference
The third Extreme Solar System conference was held between Nov 29 to Dec 4th, in Kona, Hawaii, on the 20th anniversary of the first exoplanet detection around a main sequence star. This astrobite gives a brief overview of the conference.
Studying the pulse of a galaxy: model and observations
Today we review a study searching for a way to measure the ages of stars in a galaxy. The quantity of long period variable stars gives information about the life cycle of a galaxy, and the authors explain that with their new technique it is possible to take the “pulse” of a galaxy.
