The Araucaria Project. The distance to the Small Magellanic Cloud from late-type eclipsing binaries
Dariusz Graczyk, Grzegorz Pietrzynski, Ian B. Thompson +12
We present a distance determination to the Small Magellanic Cloud (SMC) based on an analysis of four detached, long period, late type eclipsing binaries discovered by the OGLE Surv…
Physical parameters and the projection factor of the classical Cepheid in the binary system OGLE-LMC-CEP-0227
B. Pilecki, D. Graczyk, G. Pietrzyński +14
A novel method of analysis of double-lined eclipsing binaries containing a radially pulsating star is presented. The combined pulsating-eclipsing light curve is built up from a pur…
The Araucaria Project. A Distance Determination to the Local Group Spiral M33 from Near-Infrared Photometry of Cepheid Variables
W. Gieren, M. Gorski, G. Pietrzynski +10
Motivated by an amazing range of reported distances to the nearby Local Group spiral galaxy M33, we have obtained deep near-infrared photometry for 26 long-period Cepheids in this…
The Eclipsing Binary Cepheid OGLE-LMC-CEP-0227 in the Large Magellanic Cloud: pulsation modelling of light and radial velocity curves
M. Marconi, R. Molinaro, G. Bono +10
We performed a new and accurate fit of light and radial velocity curves of the Large Magellanic Cloud (LMC) Cepheid --OGLE-LMC-CEP-0227-- belonging to a detached double-lined eclip…
An eclipsing binary distance to the Large Magellanic Cloud accurate to 2 per cent
G. Pietrzyński, D. Graczyk, W. Gieren +25
In the era of precision cosmology it is essential to determine the Hubble Constant with an accuracy of 3% or better. Currently, its uncertainty is dominated by the uncertainty in t…
