ETH welcomes the ERIS Consortium to the Hönggerberg!
On 19-20 July, approximately 30 scientists and engineers representing five partner institutions met on the ETH Honggerberg campus to review progress on the Enhanced Resolution Imager and Spectrograph (ERIS) under development for the European Southern Observatory (ESO) Very Large Telescope (VLT). The ERIS consortium, comprised of the Max-Planck-Institute for Extraterrestrial Physics (PI: R. Davies), the […]

Workshop on Circumplanetary Disks
Twenty-eight NCCR PlanetS researchers representing six out of the seven research projects met on 7 June at the ETH in Zurich to discuss the properties of circumplanetary disks thought to exist around forming gas giant planets. Many models for the formation of the largest satellites of the gas/ice giants in the Solar System assume such […]

On the variety of asteroid interiors
Asteroid interiors in the early solar system – from fluffy snowballs to internal magma oceans In the nascent solar system, the building blocks of terrestrial planets – asteroids of dozens of kilometers in size – were internally heated by the decay of radioactive elements. The amount of radionuclides present in a single asteroid determined its […]

Water in the atmosphere of Kappa And b
New estimate of the water abundance in a planetary mass object spatially resolved from its host star. Dr. Kamen Todorov of ETH led a team that modelled the spectrum of Kappa And b. We hope to coordinate our efforts in this area through the NCCR PlanetS and apply similar techniques to other directly imaged planets. […]

First Circumbinary Planet System with Disc
Planet-hunting SPHERE Images First Circumbinary Planet System with Disc HD 106906AB is a double star located in the constellation of Crux (The Southern Cross). Astronomers had long suspected that this 13 million-year-old stellar duo was encircled by a debris disc, due to the system’s youth and characteristic radiation. However, this disc had remained unseen — […]

Baby-planets around a nearby star
This graphic is an artist’s conception of the young massive star HD100546 and its surrounding disk. Image Credit: P. of Marenfeld & NOAO/AURA/NSF An international team including ETH scientists has discovered for new evidence that planets are forming around a star about 335 light years from Earth. The team found emission from carbon monoxide molecules […]
