Interstellar extinction of classical Cepheids from neighboring stars I. Methodology and application to 16 Galactic Cepheids
Wilma Kiviaho, Pierre Kervella, Mika Juvela +21
Galactic Cepheid variable stars are fundamental calibrators of the cosmic distance scale through their Period-Luminosity (PL) relation. The high-precision parallaxes expected from…
GIARPS simultaneous optical and infrared high-spectral-resolution observations of Cepheids I. Limb darkening from cross-correlated radial velocities
N. Nardetto, R. S. Rathour, M. C. Bailleul +17
The Baade-Wesselink method, while theoretically applicable for calibrating the distance scale via Cepheids, is not currently employed in the cosmic distance ladder. There are vario…
Multi-chromatic observations of classical Cepheids using the CHARA Array interferometer: Surface brightness-colour relation, projection factor, and limb-darkening
M. C. Bailleul, N. Nardetto, D. Mourard +28
The Baade-Wesselink (BW) method compares the linear and angular variations of Cepheids to derive their distance. This method is limited, however, by the projection factor, which re…
Tracing grain growth in the forming prestellar core L1506C with 3D modeling of Herschel, IRAM, and CFHT observations
E. Zhu, I. Ristorcelli, K. Demyk +5
In the early phases of star formation, properties of prestellar cores are commonly inferred from observations of thermal dust emission and thus depend on dust properties, which mus…
Reddening maps of the Magellanic Clouds using spectral energy distribution fitting of red giants
H. Netzel, G. Pietrzyński, M. Górski +9
Robust reddening maps of the Large and Small Magellanic Clouds (LMC/SMC) are crucial for a wide range of astrophysical studies, including the calibration of the cosmic distance lad…
Finding the elusive RR Lyrae companions via speckle imaging
R. Salinas, V. Kalari, G. Hajdu +25
Despite their key role in astrophysics, the binary properties of RR Lyrae stars (RRL) remain almost completely unknown since only a single RRL is confirmed as belonging to a binary…
High-contrast imaging of Galactic Cepheids with VLT/SPHERE
A. Gallenne, P. Kervella, N. R. Evans +10
Cepheids are key distance indicators and benchmarks for stellar evolution, yet most of them are members of binary or multiple systems. While spectroscopic surveys and Gaia proper-m…
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…
Surface brightness-colour relations of Milky Way and Magellanic Clouds classical Cepheids based on Gaia magnitudes
M. C. Bailleul, N. Nardetto, V. Hocdé +12
Aims: We derive SBCRs for classical Cepheids in the Milky Way and in the Magellanic Clouds using the photometric data available in the Gaia database, and we quantify the metallicit…
Surface brightness-colour relations of Cepheids calibrated by optical interferometry
M. C. Bailleul, N. Nardetto, V. Hocdé +12
Surface brightness-colour relations (SBCRs) are widely used to determine the angular diameters of stars. They are in particular used in the Baade-Wesselink (BW) method of distance…
