Reconstruction of Cepheid Radial Velocity Curves from the shape of the V-band Light Curves
V. Hocdé, P. Moskalik, N. Nardetto +17
This paper aims to develop the first method to reconstruct the shape of the RV curves of short-period fundamental-mode Cepheids, based exclusively on their pulsation period and the…
Period-Luminosity Relations for Galactic Type II Cepheids in the Sloan bands
W. Narloch, G. Hajdu, G. Pietrzynski +7
Type II Cepheids (T2Ceps), alongside RR Lyrae stars, serve as important distance indicators for old population II stars due to their period-luminosity (PL) relations. However, stud…
Non-evolutionary effects on period change in Magellanic Cepheids
R. S. Rathour, R. Smolec, G. Hajdu +5
Classical Cepheids are a cornerstone class of pulsators, fundamental to testing stellar evolution and pulsation theories. Their secular period changes, characterized through …
Toward early-type eclipsing binaries as extragalactic milestones: IV. Physical properties of three detached O/B-type systems in the LMC
Mónica Taormina, G. Pietrzyński, R. -P. Kudritzki +10
We present a complete set of physical parameters for three early-type eclipsing binary systems in the Large Magellanic Cloud (LMC): OGLE LMC-ECL-17660, OGLE LMC-ECL-18794, and HV 2…
Circumstellar emission of Cepheids across the instability strip: Mid-infrared observations with VLTI/MATISSE
V. Hocdé, A. Matter, N. Nardetto +14
The circumstellar envelopes (CSE) of Cepheids are still not well characterized despite their potential impact on distance determination via both the period-luminosity relation and…
Precise physical parameters of three late-type eclipsing binary giant stars in the Large Magellanic Cloud
G. Rojas García, D. Graczyk, G. Pietrzyński +17
Detached eclipsing binaries (DEBs) allow for the possibility of precise characterization of its stellar components. They offer a unique opportunity to derive their physical paramet…
Period-luminosity and period-luminosity-metallicity relations for Galactic RR Lyrae stars in the Sloan bands
W. Narloch, G. Hajdu, G. Pietrzynski +6
RR Lyrae stars are excellent tracers of the old population II due to their period-luminosity (PL) and period-luminosity-metallicity (PLZ) relations. While these relations have been…
Towards early-type eclipsing binaries as extragalactic milestones: III. Physical properties of the O-type eclipsing binary OGLE LMC-ECL-21568 in a quadruple system
Mónica Taormina, R. -P. Kudritzki, B. Pilecki +8
We present the results from a complex study of an eclipsing O-type binary (Aa+Ab) with the orbital period days, that forms part of a higher-order multiple system…
