How many astrophysicists does it take to catch a RATT?
Astronomers will literally see a very young star running away from its peers and call it a RATT.
Wreaking Havoc with a Stellar Fly-By
You can’t model RW Aurigae as a single star with a disk of material around it, because there is a second star. And you can’t model it as a regular old binary system either, because there are interactions between the stars and the asymmetric disk. The authors of today’s paper create a comprehensive hydrodynamic model that considers many different observations of RW Aurigae.
Searching for Giant Planets Around Baby Stars
How long does planetary migration take? Crockett et al. look for the answer by searching for hot Jupiters around extremely young stars.
First GASPs of Star Formation in Taurus
The well-known constellation Taurus is home to many young stars, and the details of star formation are explained by observing far-infrared radiation from several of these objects with the Herschel space observatory.
