An absolute calibration of the near-infrared Period-Luminosity Relations of Type II Cepheids in the Milky Way and in the Large Magellanic Cloud
Piotr Wielgórski, Grzegorz Pietrzyński, Bogumił Pilecki +29
We present time-series photometry of 21 nearby Type II Cepheids in the near-infrared J, H and Ks passbands. We use this photometry, together with the Third Gaia Early Data Release…
The occurrence of Binary Evolution Pulsators in the classical instability strip of RR Lyrae and Cepheid variables
P. Karczmarek, G. Wiktorowicz, K. Iłkiewicz +5
Single star evolution does not allow extremely low-mass stars to cross the classical instability strip (IS) during the Hubble time. However, within binary evolution framework low-m…
OGLE Collection of Star Clusters. New Objects in the Outskirts of the Large Magellanic Cloud
M. Sitek, M. K. Szymański, D. M. Skowron +13
The Magellanic System (MS), consisting of the Large Magellanic Cloud (LMC), the Small Magellanic Cloud (SMC) and the Magellanic Bridge (MBR), contains diverse sample of star cluste…
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…
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…
