Discovery of a peculiar Cepheid-like star towards the northern edge of the Small Magellanic Cloud
J. B. Marquette, P. Tisserand, P. Francois +37
For seven years, the EROS-2 project obtained a mass of photometric data on variable stars. We present a peculiar Cepheid-like star, in the direction of the Small Magellanic Cloud,…
R Coronae Borealis stars in the Galactic Bulge discovered by EROS-2
P. Tisserand, J. B. Marquette, P. R. Wood +33
Rare types of variable star may give unique insight into short-lived stages of stellar evolution. The systematic monitoring of millions of stars and advanced light curve analysis t…
Limits on the Macho Content of the Galactic Halo from the EROS-2 Survey of the Magellanic Clouds
P. Tisserand, L. Le Guillou, C. Afonso +35
The EROS-2 project was designed to test the hypothesis that massive compact halo objects (the so-called ``machos'') could be a major component of the dark matter halo of the Milky…
Removing the Microlensing Blending-Parallax Degeneracy Using Source Variability
R. J. Assef, A. Gould, the EROS-2 +2
Microlensing event MACHO 97-SMC-1 is one of the rare microlensing events for which the source is a variable star, simply because most variable stars are systematically eliminated f…
The OGLE-II event sc5_2859 : a Classical Nova outburst?
C. Afonso, J. F. Glicenstein, A. Gould +3
The OGLE-II event sc5_2859 was previously identified as the third longest microlensing event ever observed. Additional photometric observations from the EROS (Experience de Recherc…
Galactic Bulge Microlensing Optical Depth from EROS-2
C. Hamadache, L. Le Guillou, P. Tisserand +34
We present a new EROS-2 measurement of the microlensing optical depth toward the Galactic Bulge. Light curves of clump-giant stars distributed over of t…
Type Ia supernova rate at a redshift of ~ 0.1
G. Blanc, C. Afonso, C. Alard +58
We present the type Ia rate measurement based on two EROS supernova search campaigns (in 1999 and 2000). Sixteen supernovae identified as type Ia were discovered. The measurement o…
A Quest for PMS candidate stars at low metallicity: Variable HAe/Be and Be stars in the Small Magellanic Cloud
W. J. de Wit, J-P. Beaulieu, H. J. G. L. M. Lamers +3
We report the discovery of 5 new Herbig Ae/Be candidate stars in the Small Magellanic Cloud in addition to the 2 reported in Beaulieu et al. (2001). We discuss these 7 HAeBe candid…
Bulge Microlensing Optical Depth from EROS 2 observations
C. Afonso, J. -N. Albert, C. Alard +7
We present a measurement of the microlensing optical depth toward the Galactic bulge based on the analysis of 15 contiguous1 square degrees fields centered on (l=2.5 deg, b=-4.0 de…
Observation of periodic variable stars towards the galactic spiral arms by EROS II
F. Derue, J. B. Marquette, S. Lupone +11
We present the results of a massive variability search based on a photometric survey of a six square degree region along the Galactic plane at (, ) a…
Variability and spectral classification of LMC giants: results from DENIS and EROS
M-R. L. Cioni, J-B. Marquette, C. Loup +4
We present the first cross-identifications of sources in the near-infrared DENIS survey and in the micro-lensing EROS survey in a field of about 0.5 square degrees around the optic…
EROS and MACHO Combined Limits on Planetary Mass Dark Matter in the Galactic Halo
EROS Collaboration, MACHO Collaboration
The EROS and MACHO collaborations have each published upper limits on the amount of planetary mass dark matter in the Galactic Halo obtained from gravitational microlensing searche…
EROS Variable Stars : Discovery of Beat Cepheids in the Small Magellanic Cloud and the effect of metallicity on pulsation
J. P. Beaulieu, M. Krockenberger, D. D. Sasselov +27
We report the discovery of eleven beat Cepheids in the Small Magellanic Cloud, using data obtained by the EROS microlensing survey. Four stars are beating in the fundamental and fi…
Metallicity Effects on the Cepheid Extragalactic Distance Scale from EROS photometry in LMC and SMC
D. D. Sasselov, J. P. Beaulieu, C. Renault +30
This is an investigation of the period-luminosity relation of classical Cepheids in samples of different metallicity. It is based on 481 Cepheids in the Large and Small Magellanic…
The effect of metallicity on the Cepheid distance scale and its implications for the Hubble constant () determination
J. P. Beaulieu, D. D. Sasselov, C. Renault +30
Recent HST determinations of the expansion's rate of the Universe (the Hubble constant, H_0) assumed that the Cepheid Period-Luminosity relation at V and I are independent of metal…
Observational Limits on Machos in the Galactic Halo
