Far-red spectroscopy of peculiar stars and the GAIA mission
نویسنده
چکیده
The coming GAIA Cornerstone mission by ESA will provide micro-arcsec astrometry, ∼10 bands photometry and far-red spectroscopy for a huge number of stars in the Galaxy (109). GAIA spectroscopy will cover the range 8480–8740 Å which includes the CaII triplet and the head of the Paschen series. In this paper we address the diagnostic potential of this wavelength range toward detection of peculiar stars.

Spectroscopy, Photometry and Micro-arcsec Astrometry of Binaries with the Gaia Space Mission and with the Rave Experiment
GAIA astrometric mission of ESA will be very efficient in discovering binary and multiple stars with any orbital period, from minutes to millions of years. Main parameters of the revised mission design are presented. Next we estimate the fraction of binary stars discovered by means of astrometry, photometry and on-board spectroscopy. Finally we summarize observations that confirm the ability to...
متن کاملNew high resolution synthetic stellar libraries for the Gaia Mission
High resolution synthetic stellar libraries are of fundamental importance for the preparation of the Gaia Mission. We present new sets of spectral stellar libraries covering two spectral ranges: 300 –1100 nm at 0.1 nm resolution, and 840 – 890 nm at 0.001 nm resolution. These libraries span a large range in atmospheric parameters, from super-metalrich to very metal-poor (-5.0 <[Fe/H]<+1.0), fro...
متن کاملThe Diffuse Interstellar Band at 8620 Å: a Good Reddening Tracer for Gaia
We report about a suprisingly good correlation between the equivalent width of the diffuse interstellar band (DIB) at 8620 Å and the interstellar reddening. Such a correlation offers bright prospects in using the 8620 Å DIB as a tracer of the extinction through the Galaxy in the context of the GAIA mission by ESA. The GAIA mission planned by ESA is aimed to provide astrometry in the 10 microarc...
متن کاملThe Gaia mission Pulsating stars with Gaia
Gaia is a cornerstone mission of the European Space Agency (ESA) selected in 2000, with a target launch date of 2011. The Gaia mission will perform a survey of about 1 billion sources brighter than V = 20. Its goal is to provide astrometry leading to parallaxes, proper-motions and positions. Astrometric data are complemented by multicolour photometry and a spectroscopic instrument (up to V = 17...
متن کاملGaia: Origin and Evolution of the Milky Way
GAIA is a short-listed candidate for the ESA Cornerstone mission C5, meeting the ESA Survey Committee requirement for an observatory mission, dedicated to astrometry, providing 10 micro-arcsecond accuracy at 15th magnitude. The GAIA mission concept follows the dramatic success of the ESA HIPPARCOS mission, utilising a continuously scanning spacecraft, accurately measuring 1-D coordinates along ...
