The Araucaria Project. An improved distance to the Sculptor spiral galaxy NGC 300 from its Cepheid variables

W. Gieren, G. Pietrzynski, A. Walker +8

In a previous paper, we reported on the discovery of more than a hundred new Cepheid variables in the Sculptor Group spiral NGC 300 from wide-field images taken in the B and V phot…

Potential Direct Single-Star Mass Measurement

H. Ghosh

We analyze the lightcurve of the microlensing event OGLE-2003-BLG-175/MOA-2003-BLG-45 and show that it has two properties that, when combined with future high resolution astrometry…

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…

OGLE-2003-BLG-238: Microlensing Mass Estimate of an Isolated Star

Guangfei Jiang, D. L. DePoy, A. Gal-Yam +38

Microlensing is the only known direct method to measure the masses of stars that lack visible companions. In terms of microlensing observables, the mass is given by M=(c^2/4G)\tild…

The angular size of the Cepheid L Car: a comparison of the interferometric and surface brightness techniques

P. Kervella, P. Fouque, J. Storm +5

Recent interferometric observations of the brightest and angularly largest classical Cepheid, L Carinae, with ESO's VLT Interferometer (VLTI) have resolved with high precision the…

The effect of metallicity on the Cepheid Period-Luminosity relation from a Baade-Wesselink analysis of Cepheids in the Galaxy and in the Small Magellanic Cloud

Jesper Storm, Bruce W. Carney, Wolfgang P. Gieren +3

(ABRIDGED) We have applied the near-IR Barnes-Evans realization of the Baade-Wesselink method as calibrated by Fouque & Gieren (1997) to five metal-poor Cepheids with periods betwe…
