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
EROS collaboration, C. Renault, C. Afonso +40
We present final results from the first phase of the EROS search for gravitational microlensing of stars in the Magellanic Clouds by unseen deflectors (machos: MAssive Compact Halo…
EROS VARIABLE STARS : FUNDAMENTAL-MODE AND FIRST OVERTONE CEPHEIDS IN THE BAR OF THE LARGE MAGELLANIC CLOUD
J. P. Beaulieu, P. Grison, W. Tobin +27
We present CCD phase-binned light curves at 490 nm for 97 Cepheid variable stars in the bar of the LMC. The photometry was obtained as part of the French EROS project and has excel…
