Exoplanet Observations with the E-ELT

Exoplanet Observations with the E-ELT

Exoplanet research is one of the major science drivers for the future 39-m European Extremely Large Telescope (E-ELT). A comprehensive suite of instruments will provide the community with the ability to conduct a wide range of outstanding exoplanet science programmes. In addition, some combinations of instruments will indeed be more powerful than the sum of the…

Science with the Atacama Pathfinder Experiment

Science with the Atacama Pathfinder Experiment

After the success of the 2012 Ringberg meeting on APEX science where about 70 participants discussed exciting APEX science ranging from our Solar System to distant galaxies in the Early Universe, time is ripe to review what has been accomplished since then and to look into science opportunities for the next years. Since its inauguration in…

A dark matter ring around Earth?

Al recente meeting della American Geophysical Union (AGU), un esperto di telecomunicazioni e satelliti GPS dell'Università del Texas, Ben Harris, ha annunciato che una serie di misure effettuate per determinare la massa della Terra, utilizzando i dati GPS, danno sorprendentemente un valore superiore rispetto a quello attualmente accettato dalla International Astronomical Union (IAU). Secondo lo scienziato, questa…

Testing the string theory with astronomy

Il "Sacro Graal" della fisica potrebbe venire alla luce. E' oggi quello che un gruppo di fisici del Department of Physics, Astronomy and Geosciences presso la Towson University (TU) sperano di aver trovato dopo quasi mezzo secolo di ricerche: verificare sperimentalmente una delle teorie più elusive e più complicate da capire, la teoria delle stringhe, osservando il…

Ionising processes in atmospheric environments of planets, Brown Dwarfs, and M-dwarfs

Ionising processes in atmospheric environments of planets, Brown Dwarfs, and M-dwarfs

The atmospheres of planets and very low-mass (VLM) stars are cold enough that clouds form and affect the local chemistry and the spectral appearance. Prominent planetary examples are the giant gas planet HD189733b and the super-Earth GJ1214b in which hazes block the view onto the gaseous atmosphere in the optical and mid-IR spectral ranges. Similar effects…

Astrotomography II – Imaging at the micro-arcsecond scale

Astrotomography II – Imaging at the micro-arcsecond scale

Astrotomography is a generic term for indirect mapping techniques that can be applied to a huge variety of astrophysical systems, ranging from planets via single stars and binaries to active galactic nuclei. With this workshop we aim at consolidating the success of a previous workshop dedicated to this topic, and plan to bring together people…
