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…
