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...
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...
Spectrophotometric characterization of interstellar comet 2I/Borisov before perihelion passage
Comets are primitive objects which formed in the outer parts of the proto-planetary disk, beyond the snow line. They can provide key information about the...
Spectrophotometric characterization of minor planets using VISTA-VHS survey - MOVIS catalog
Using the observations performed by VISTA-VHS survey we obtained the near-infrared colors of 35 000 minor planets. This survey uses Y, J, H, and Ks filters to...
Spectrophotometric investigations of the blue compact dwarf galaxy Mrk 35
Preliminary results from a detailed spectrophotometric analysis of the blue compact dwarf galaxy (BCD) Mrk 35 are presented. We have performed deep UBVRI broad...
Spectrophotometric Monitoring of OJ 287 During 1998 Minimum: Evidence for Accretion Disk
Broad band B V R I, CCD photometry and spectrophotometry observations are presented for the blazar OJ 287. A nightly monitoring was carried out at San Pedro...
