We study the structure and evolution of the magnetic field of the quiet Sun by investigating weak spectro-polarimetric signals. To this end, we observed a quiet...

We describe an unusual undergraduate course that has been running successfully for over ten years and is built around a two-week field trip to Tenerife. The...

STEPHI is a photometry network that aims to obtain data to reach a better understanding of the physics of stellar interiors by seismology of δ Scuti stars. For...

A new mid-infrared array camera has been recently put in operation with the 2.1 m telescope of the OAN at San Pedro Martir, Mexico. Calibrated 8.7, 9.8 and 12.5...

Beamswitch experiments located at Teide Observatory, Tenerife operate at 10, 15, 33 GHz. An area of ˜1 steradian has been covered at angular scales from 5 to 20...

Since May 2005 the Tenerife Infrared Polarimeter II (TIP-II) has been operational at the Vacuum Tower Telescope on Tenerife. The core of the polarimeter is a...

During the early stages of planetary formation, planets suffer severe changes in their physical and orbital properties due to internal and external forces...
