Some polarized lines of the second solar spectrum (SrI, CaI, BaII, C2, MgH, NdII) observed at the Meudon Solar Tower spectropolarimeter
Jean-Marie Malherbe
The second solar spectrum is the spectrum of the Stokes parameter Q (linear polarization) close to the solar limb. It is made of a few polarized lines with Q/I of about 1% (such as…
Polarized lines of the second solar spectrum (SrI, SrII, CaI, BaII) observed at the Pic du Midi Turret Dome spectropolarimeter with the slit orthogonal to the limb
Jean-Marie Malherbe
The second solar spectrum is the spectrum of the Stokes parameter Q (linear polarization) close to the solar limb. It differs significantly of the usual intensity spectrum (Stokes…
Datacubes of H, CaII K, CaII H and H line profiles of the full solar disk recorded daily at Meudon observatory since 2017 and some typical profiles of solar features
Jean-Marie Malherbe
Systematic observations of the Sun are performed at Meudon observatory since 1908 under the form of monochromatic images. However, a major technical improvement occurred in 2017; s…
Weak polarized lines of the second solar spectrum (Na, Al, H, He, Ti, Li, Sc, C2 and MgH) observed at the Pic du Midi turret dome
Jean-Marie Malherbe
The second solar spectrum is the solar spectrum of Stokes parameter Q observed in linear polarization close to the solar limb. It differs significantly of the usual intensity spect…
70 years of spectroscopy of the photosphere and the solar chromosphere at the Pic du Midi Observatory (1956-2026)
Jean-Marie Malherbe
Observations of the solar corona at the Pic du Midi began with Bernard Lyot and his spectro coronagraph installed on the multi-purpose equatorial mount of the Baillaud cupola. It w…
150 years of ground-based solar instrumentation at Meudon observatory (1876-2026)
Jean-Marie Malherbe
The Sun has been observed through a telescope for four centuries. However, its study made a prodigious leap at the end of the nineteenth century with the appearance of photography…
