Making emphasis on observations that have included some type of polarization analysis, I concentrate on two subjects. First, the vector magnetic field...
Polarizing properties of grazing-incidence X-ray mirrors - Comment
We show that grazing-incidence telescopes, like those used for X-ray imaging, present negligible instrumental polarization. This property does not depend on the...
This contribution is a report on a test campaign carried out by the IAC, in collaboration with Construcciones Aeronauticas, S.A. (CASA) as a main contrac tor...
Spectropolarimetry of solar faculae - High spatial resolution results
A new method to measure the magnetic field strength of small-scale solar magnetic concentrations is presented. It is based on the center of gravity method...
Study of the planetary system HD 46375 with CoRoT and ground-based support
At the end of 2008, on ideas of teams from the Observatoire de la Côte d’Azur (OCA) and IAC, the CoRoT satellite observed the star HD 46375, known to host a non...
Surface Heterogeneity, Physical, and Shape Model of Near-Earth Asteroid (52768) 1998 OR2
On 2020 April 29, the near-Earth object (52768) 1998 OR2 experienced a close approach to Earth at a distance of 16.4 lunar distances (LD). 1998 OR2 is a...
The CLASP2 space experiment achieves an unprecedented map of the Sun’s magnetic field from the photosphere up to the base of the corona
Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the...
The international team of the “Chromospheric LAyer Spectro-Polarimeter” (CLASP) space missions, which includes three scientists of the Instituto de Astrofísica...
The COSMO Chromosphere and Prominence Magnetometer
The Chromosphere and Prominence Magnetometer (ChroMag) is a synoptic instrument with the goal of quantifying the intertwined dynamics and magnetism of the solar...
