Transport of the magnetic flux away from a decaying sunspot via convective motions
Chenxi Zheng, Thierry Roudier, Brigitte Schmieder +5
Aims. The aim of this paper is to consider relationship between the decay of sunspots and convection via the motion of the family of granules and how the diffusion mechanism of mag…
Optical capabilities of the Multichannel Subtractive Double Pass (MSDP) for imaging spectroscopy and polarimetry at the Meudon Solar Tower
Jean-Marie Malherbe, Pierre Mein, Frédéric Sayède
The Meudon Solar Tower (MST) is a 0.60 m telescope dedicated to spectroscopic observations of solar regions. It includes a 14-meter focal length spectrograph which offers high spec…
Note concerning a high spectral resolution slicer for imaging spectro-polarimetry with the new generation Multichannel Subtractive Double Pass (MSDP) onboard the future EST telescope
Jean-Marie Malherbe, Pierre Mein, Frédéric Sayède +1
Imaging spectroscopy is intended to be coupled with adaptive optics (AO) on large telescopes, such as EST, in order to produce high spatial and temporal resolution measurements of…

Solex observations for the BASS2000 database, a collaboration PRO-AM
Jean-Marie Malherbe, Florence Cornu, Isabelle Bualé
Systematic observations of the chromosphere and the photosphere started in Meudon Observatory 115 years ago with Deslandres spectroheliograph. An exceptional collection of more tha…
Spectro-polarimetry at the Pic du Midi Turret Dome and new observations of the solar CaII K line
Jean-Marie Malherbe, Thierry Roudier
We summarize in this paper the spectro-polarimetric methods used at the Pic du Midi Turret Dome in spectroscopic or imagery mode. The polarimeters and spectrograph allow the cartog…
