Instruments

DIPOL-2

  • broad-band polarimetry simultaneously in three bands: blue, green, and red;
  • achieved polarimetric accuracy 10^-5 for a 10mag star at a 4m telescope;
  • designed and built in cooperation between KIS and FINCA (Turku University, Finland (Piirola et al. 2014);
  • telescopes: 3 copies of DIPOL-2 are deployed at the KVA60 (La Palma), WHT (La Palma, visiting instrument), UH2.2m (Mauna Kea, visiting instrument), H80 (Haleakala);
  • science: to measure geometrical albedo of exoplanets using polarimetry and characterize their atmosphere and cloud composition.

InnoPol+AO

  • imaging polarimeter combined with the Hokupa'a-85 curvature AO system;
  • wavelength range 550-950nm, FOV 3"x3", image resolution 30mas at 600nm;
  • designed and built in cooperation between KIS and IfA/Maui, University of Hawaii, USA (Harrington et al. 2014);
  • telescope: the 3.7m AEOS telescope (Haleakala), currently under final commissioning;
  • science: to search for and characterize planetosimals in protoplanetary disks, to investigate atmospheres of Solar system planetary bodies.

HiViS

  • Visible spectropolarimeter with high resolution (HiViS, 50,000) and low resolution (LoViS, 5000) modes with charge shuffling. (Harrington et al. 2006, 2008, 2010, 2011, 2013);
    Near Infrared R=30,000 JHK spectrograph is to be upgraded to include a polarimetric unit;
  • telescope: the 3.7m AEOS telescope (Haleakala), available to us through collaboration with the IfA/Maui;
  • science: to detect molecules in exoplanetary atmospheres in the optical and NIR regions and chracterize their atmosphere composition.

InnoPol-2+AO

  • an analogue of the InnoPol imaging polarimeter to be combined with a night-time AO system and to be built within the HotMol project;
  • telescope: GREGOR@night, Tenerife;
  • science: to search for and characterize planetosimals in protoplanetary disks, to investigate atmospheres of Solar system planetary bodies.

BioPol

  • a laboratory experiment to measure bidirectional reflection functions in polarized light from biological and non-biological samples;
  • two copies are deployed at IfA/Maui and KIS (Berdyugina et al. 2014);
  • telescopes: the BioPol concept is developed for the next-generation extremely-large telescopes, such as the Colossus Telescope which will be capable of detecting signatures of both organic life and civilizations (Kuhn et al. 2013);
  • science: to model polarized spectra of habitable planets and develop novel approach for remote detection of extraterrestrial life;

Photometry

  • precise photometry of stars with transiting planets is carried out by our collaborators from Searchlight observatory;
  • telescopes: 50cm at Ranchi Hidalgo, NM; 50cm at San Pedro de Atacama, Chile; 60cm at Observatorio Sierra Contraviesa, Granada;
  • science: to support our polarimetric measurements, to monitor intrinsic stellar variability due to magnetic activity, and to characterize reflectance of planetary atmospheres.
