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.
Ten years after launch, financial problems may mean the demise of the Spitzer space telescope. Today, we review its history and discuss its possible future.
Let’s face it: some astronomical systems don’t make any sense. Join us for a look at the history of some of these terms, as we try to understand why stellar spectral classification and the magnitude system work like they do.
Last week, NASA held the 2014 astrophysics senior review in Washington, the results of which will determine the fate of 11 missions.
A recent result on the commonality of exoplanets has made headlines, but has it for the right reasons?
Most binary stars probably formed at the same time, meaning all stars in the same system should have the same age. The authors of this paper analyze a stellar binary system where one star appears to be lying about its age, as one star appears 3 billion years older than its companion.
Astronomers are used to “looking back in time” when they view distant stars and galaxies. The authors of this paper take a different look back in time and search the internet for evidence of time travelers.
The next American Astronomical Society meeting is right around the corner; we’re getting ready to keep you up to date on all the happenings!
Today we take a look back to 1916, when distances were measured in light years and uncertainties weren’t to be included in publications. The nearly 100-year old discovery of a small star has large implications for our understanding of stellar astrophysics, even today.
