Equipe de recherche:
Astrophysique de Grands Relevés
Research Interests: astrophysics and galactic structure
Late stages of stellar evolution: Stars on the Asymptotic Giant
Branch
- AGB stars as tracer of the stellar populations in the Central Galaxy
- Participation in the ISOGAL
and the DENIS survey
- Long-period Variables using
MACHO,OGLE and EROS data (Glass & Schultheis 2003)
- Mass-loss of AGB stars
in different galactic environments
- Relation between pulsation
and mass-loss Comparison between model atmospheres (MARCS) and K/M giants (spectra,
colours)
- Influence of metallicity
on the molecular and atomic features of K/M giants ( Schultheis et al. 2002,
2003)
(in collaboration with A. Omont (IAP), G. Simon (Obs.de Meudon),
I.S. Glass (SAAO), T. Lebzelter, B. Aringer (IfA, Vienne), M.R. Cioni (ESO), J.
Blommaert, M.A.T. Groenewegen (Leuven), S. Charlot (MPA), G. Bruzual (Venezuela))
Stellar populations :
- Stellar populations
in the Inner Galactic Bulge (Schultheis et al. 2003)
- Near-IR spectra of stellar
populations the Inner Galactic Bulge (Schultheis et al. 2003)
- Determination of abundances in the Bulge (Schultheis et al. 2003) Interstellar
extinction (Schultheis et al. 1999) - NEW : Extended
interstellar extinction map between -30 < l < 30 (map)
- Metallicity map of the galactic Bulge
- Formation of the Galaxy
- Kinematics
in the galactic Bulge (radial velocities, proper motions)
(in collaboration
with A. Robin, C. Reyle (Obs. de Besançon), A. Lançon (Obs. de Strasbourg), A.
Gomez, M. Haywood, V. Hill (Obs. de Meudon /GEPI), A. Omont, C. Alard (IAP), S.
Ganesh, D. Ojha (India))
Involved projects :
- The CFHTLS survey :A
data base of stellar objects including proper motions (in collaboration
with A.Robin, A. Omont, C. Alard and the
TERAPIX center (Y. Mellier))
-
Stellar population in the Bulge with CFHTLS : 16 hours
of observing time with MEGACAM for semester 2004a
(
CFHT )
-
SIRGAL: A study of the Inner Galaxy using
SIRTF : Co-I of the SIRGAL project
- GIRAFFE:
Abundances and kinematics of the galactic Bulge (in collaboration with A.Gomez,
V.Hill , M.Haywood (GEPI/ Meudon ), M. Zoccali (ESO), F. Royer ( Geneve)
- GIRAFFE: 2 nights of observing time: M giants in
the galactic Bulge: abundances and kinematics
