The Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) is a VUV spectropolarimeter optimized for measuring the linear polarization of the Lyman-alpha line...
One of the biggest challenges in heliophysics is to decipher the magnetic structure of the solar chromosphere. The importance of measuring the chromospheric...
This article shows how some recent developments in the observation and theoretical modeling of weak polarization signals in chromospheric spectral lines are...
Chromospheric modelling in late-type dwarfs. I - Quiescent objects
Attention is given to problems which arise when an attempt is made to use observational material to clarify the mechanisms responsible for the heating of the...
Chromospheric modelling in late-type dwarfs. II - CES observations of active and quiescent stars
The characteristics of the chromospheres of late-type dwarf stars were studied using the CoudeEchelle Spectrograph (CES) at ESO and the IUE. The study focused...
