Welcome to the homepage of the
Monte Rosa GAIA 2002
International Conference on
"GAIA spectroscopy, science and technology"
to be held in Gressoney St. Jean
(Valle d'Aosta, Italy, close to the border with both France and Switzerland,
see map) on coming Sept 9-12, 2002 at the Residenza del Sole Congress
Center, from where the view on Gressoney and Monte Rosa on the background
(the second highest mountain in the Alps, peaking at 4633 m) is similar to
the winter image on left.
GAIA has been selected as a coming
ESA Cornerstone mission and it is designed to obtain
extremely precise astrometry (in the micro-arcsec regime), multi-band
photometry and medium/high resolution spectroscopy for a large sample of
stars. The goals as depicted in the mission Concept
and Technology Study call for astrometry and broad band photometry
to be collected for all stars down to V~20 mag over the entire sky
(a billion stars), with brighter magnitude limits for spectroscopy and
intermediate band photometry. Each target star should be measured around a
hundred times during the five year mission life-time, in a fashion similar
to the highly successful Hipparcos operational mode.
An useful introduction to GAIA is the paper by Perryman et al. 2001 A&A 369, 339.
GAIA spectroscopy will be obtained over the
8480-8750 Ang wavelength range, centered on
the near-IR CaII triplet and the head of the Paschen series, where also
abundant FeI, SiI, MgI, NI and TiI lines cluster. The spectral resolution,
not set yet, should be around 10,000-20,000.
The conference is aimed to bring together
the large GAIA community and interested outside scientists to review science
and technical issues of its spectroscopy, with an eye on the rest of the
The Conference SOC is composed by F.Castelli, C.Chiosi, M.Cropper,
M.Gai, G.Gilmore, D.Katz, M.G.Lattanzi, L.Lindegren, F.Mignard, O.Pace,
M.A.C.Perryman, C.Turon, T.Zwitter and U.Munari (Chair). A preliminary list
of confirmed speakers includes also A.Henden, E.Milone, V.Vansevicius,
Y.Pavlenko, G.Bono, R.Wilson, M.W.Feast, P.Hauschildt and B.Plez.
The Conference's goals include:
* a review of GAIA spectroscopy and its science goals,
and among the topics considered there will be:
* an outline of spectrograph design and involved technology,
* telemetry and compression algorithms,
* evaluation of synergy with GAIA photometry and astrometry,
* legacy to ground-based spectroscopy,
* a review of tools for spectral data analysis and treatment,
* radial and rotational velocities,
* model atmospheric analysis and chemical abundances,
* spectral peculiarities of various kind, signature of mass loss and interstellar medium,
* stellar pulsation,
* binarity and eclipsing stars,
* galactic kinematics, structure and evolution from GAIA spectroscopy,
* stellar structure and evolution from GAIA spectroscopy.

Rooms have been reserved until June 15 in other
charming, full-optional, mountain-style hotels at short walking
distance (anyway, a bus shuttle service will be offered through the period
of the Conference). Click here to know how

and deadlines are:
* May 15 for early registration

A preliminary scientific program will be prepared by SOC after
registrations will be completed.
A booklet with the abstract of scheduled talks and
posters will be sent to press by July 15 and distributed at the Conference.
Its content will be uploaded to
ADS abstract service .
The breath-taking beauty of the Alps and the
old-fashioned and charming atmosphere of the Gressoney valley will
suggest many partecipants to enjoy some outdoor activities during the period
of the Conference. Prolonged launch breaks will allow relaxing and sunny
walks both in the grassy meadows and woods surrounding the Congress Center, or toward
the nearby Castle, the Village and its lake, or one of the many falls of both
sides of the valley.
For those arriving on Saturday, a hike will
be organized to Cima Regina Margherita (2356 m) on Sunday (weather
permitting) to enjoy a superb 360o view of the facing Monte Rosa
and surrounding Alps. A chair-lift will take the partecipants to ~2000 m
altitude, thus limiting to 350 m the height to hike (on an easy path in the
open). Bring with you gym or trekking shoes, a summer hat and a small
rucksack if you want to take part. The hike will be an easy one (lasting a
few hours), however be aware that the Conference organization will not
assume any responsability connected with this or other excursions or any
other outdoor activity in which you will take part during the period of the
The afternoon of Wednesday will be dedicated to
a guided tour of Aosta, main town of the region, and its surroundings
with their renowned medieval castles. Aosta still preserves many testimonies
of is past history, like the large roman theatre, the arch and the massive defensive walls. A social
dinner in a typical restaurant will conclude the tour before returning by bus to the Congress
