BRIEF DESCRIPTION OF THE PROJECT
WP1: Ground-based observation in Gaia pre and post-launch time (Pavel Koubský)
The 2m telescope will perform pre-launch spectroscopic supplementary observations for Specific Object Studies (GWP-M-720-0000) in cooperation wit G. Clementini (GWP-M-732-0000). With planned improvement of the 2m telescope and its spectrograph there is a good chance to participate in the follow-up observations in Gaia programme.
WP2:Reduction of reference star spectra ( Pavel Koubský)
Perform detailed analysis of stellar spectra with up-to-date methods and line lists in order to determine accurate and homogeneous astrophysical parameters of the calibrators.
WP3:Gaia CU7 sub-workpackage on Eruptive stars with emphasis on Be stars (Pavel Koubský)
Create a catalogue of known and suspected Be stars so that the Gaia observations can effectively improve our knowledge of this sample. This catalogue will be constructed in the form of a computer database and will contain information that will help to sort out common properties. These commo properties will be then subject of theoretical analysis base on grid of synthetic spectra and integral fluxes. Tools developped in this WP are to be applied to other type of eruptive stars.
WP 4: Gaia Software development ( Pavel Koubský)
Direct participation in the Gaia CU7 Data Processing Centre activity. After the launch of Gaia this WP can be broadened to scientific activities connected with data analysis, data archiving, data interpretation and publications. In this phase, which will continue beyond the scope of this proposal, the participation of more people should be considered.
WP5:Gaia CU7 sub-workpackage on Cataclysmic Variables ( René Hudec)
The investigation and analyses of Cataclysmic Variables and related objects (including supernovae, various classes of novae, polars and symbiotic stars) based on Gaia photometry and spectrophotometry as well as complex analyses with addional data.
WP6:Gaia CU7 sub-workpackage on Optical Counterparts of High-Energy Sources (René Hudec)
The investigation and analyses of optical counterparts of high energy sources ( X-ray binaries, optical transients, optical afterglows related to x-ray flashes an gamma-ray bursts and microquasars).based on Gaia data as well as complex analyses with addional data.
WP7: Special Variability Detection and Variability Characterization (René Hudec)
Participation in Special Variability Detection and Variability Characterization. Feasibility study of variability detection methods in spectrophotometry using simulated low dispersion Gaia data and simulated real data provided by digitised spectral Schmidt plates with objective prisma including design and development and tests of relevant algorithms and software. Designing and developing of novel algorithmes for processing of low dispersion spectra (participation of undergraduate and/or PhD students)
WP8: Simultaneous observations by robotic telescopes (René Hudec)
The Gaia analyses will be also supported by optical observations provided by the robotic telescopes and monitors (BOOTES, BART, CCD telescopes, etc.), in agreement with the requirements of the relevant workpackage for supporting ground-based observations within the CU7.
