Spectro-polarimetric observation in UV with CLASP to probe the chromosphere and transition region
The Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) is a NASA sounding-rocket experiment that was performed in White Sands in the US on September 3, 2015...
Spectro-Polarimetric Observations of Filaments in Hα and He I D3
Recordings of the full Stokes vector of filaments in the Hα and He I D3 lines were obtained at the Gregory-Coudé telescope in Locarno with the polarimeter...
Spectro-polarimetry in the era of large solar telescopes
This paper discusses some of the challenges of spectro-polarimetric observations with a large aperture solar telescope such as the ATST or the EST. The observer...
A large set of high-precision, full-Stokes spectro-polarimetric observations of prominences in He I D3, Hα, and Hβ lines has been recorded with the ZIMPOL...
Spectrograph capabilities of the European Solar Telescope
EST is a project for a 4-meter class telescope to be located in the Canary Islands. EST will be optimized for studies of the magnetic coupling between the...
Spectrograph design for the Asgard/BIFROST spectro-interferometric instrument for the VLTI
The BIFROST instrument will be the first VLTI instrument optimised for high spectral resolution up to R=25,000 and operate between 1.05 and 1.7 μm. A key...
Spectrographs for the Asgard/BIFROST beam combiner for the VLTI: optical and optomechanical design and first lab results
BIFROST, an upcoming instrument for the VLTI, is part of the Asgard Suite, a VLTI visitor instrument. It comprises two spectrograph arms that are optimised for...
Spectrophotometric Calibration of the 10-m GTC Telescope at La Palma Observatory
We propose a calibration plan for the GTC based on techniques similar to the ones used for space calibration. After studying the telescope and instrument...
