" Project Solaris and The Little Spectrograph that Could "

Stanislaw Kozlowski

(Nicolaus Copernicus Astronomical Center)

Solaris is a Polish scientific undertaking aimed at the detection and characterization of circumbinary exoplanets. To accomplish this task, a network of four fully autonomous observatories has beed deployed in the Southern Hemisphere: Solaris-1 and Solaris-2 in the South African Astronomical Observatory in South Africa, Solaris-3 in Siding Spring Observatory in Australia and Solaris-4 in Complejo Astronomico El Leoncito in Argentina. The four stations are nearly identical and are equipped with 0.5-m Ritchey-Cretien (f/15) or Cassegrain (f/10, Solaris-3) optics and high-grade 2K x 2K CCD cameras with Johnson and Sloan filter sets. The design and implementation of low-level security, data logging and notification systems, weather monitoring components, all-sky vision system, surveillance system and distributed temperature and humidity sensors will be presented. The Solaris-1 telescope is additionally fitted with a medium resolution low cost wine-bottle-size Echelle spectrograph that is operated semi-automatically. Custom hardware components have been designed to allow both spectroscopic and photometric observations. The setup is controlled via dedicated software. Apart from the hardware description, first photometric and spectroscopic results will be presented.

Seminars are also held at JAC, CFHT, and IfA.
