A solar twin in the eclipsing binary LL Aqr
D. Graczyk, R. Smolec, K. Pavlovski +11
In the course of a project to study eclipsing binary stars in vinicity of the Sun, we found that the cooler component of LL Aqr is a solar twin candidate. This is the first known s…
Orbital and physical parameters of eclipsing binaries from the ASAS catalogue - VIII. The totally-eclipsing double-giant system HD 187669
K. G. Hełminiak, D. Graczyk, M. Konacki +14
We present the first full orbital and physical analysis of HD 187669, recognized by the All-Sky Automated Survey (ASAS) as the eclipsing binary ASAS J195222-3233.7. We combined mul…
The Araucaria Project. Binary Classical Cepheids in the LMC
D. Graczyk, B. Pilecki, G. Pietrzyński +5
The status of our work on binary classical cepheid systems in the Large Magellanic Cloud is presented. We report on results from our follow up of two eclipsing binary cepheids OGLE…
RR-Lyrae-type pulsations from a 0.26-solar-mass star in a binary system
G. Pietrzynski, I. B. Thompson, W. Gieren +14
RR Lyrae pulsating stars have been extensively used as tracers of old stellar populations for the purpose of determining the ages of galaxies, and as tools to measure distances to…
