Astronomers’ industrial espionage

https://www.mpg.de/17471408/astronomers-industrial-espionage

Using radio data from the ALMA observatory and physical modelling, astronomers led by Kamber Schwarz (Max Planck Institute for Astronomy and University of Arizona) have managed to determine the mass of a potential “planet factory,” the protoplanetary disk around the star GM Aurigae. From their reconstruction, which includes a determination of the disk’s temperature profile, the astronomers deduce that the factory may just have started production: in an unstable region, conditions should be right to form a giant gas planet. The results showcase the increasing ability of astronomers to probe physical properties of planet formation as it happens.

Electrons surf the laser wave

Particle accelerators for charged particles could in future work with laser light. Researchers at the Max Planck Institute of Quantum Optics have accelerated electrons via an optical grating with evanescent waves of a perpendicularly directed laser, and thus presented a principle for innovative linear accelerators.
In their demonstration experiment, John Breuer and Peter Hommelhoff obtained an accelerating
