Preliminary results on galactic dark matter from the complete EROS2 microlensing survey
Patrick Tisserand, Alain Milsztajn
The EROS-2 collaboration has conducted a survey of the Magellanic Clouds between July 1996 and February 2003 (6.7 years), in order to search for microlensing phenomena due to putat…
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…
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…
Spectroscopic Studies of the Two Eros Candidate Microlensed Stars
J. P. Beaulieu, R. Ferlet, Ph. Grison +26
Low resolution spectroscopy, and UBVRI photometry, have been obtained for the two EROS microlensing candidates. Radial velocities indicate that both stars are members of the Large…
