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…
Interferometric Survey of Stellar Parameters: Mass of the metallic A-type binary Aur
J. Jonák, D. Mourard, J. D. Monnier +23
With the capabilities of the new visible CHARA/SPICA instrument and the multiple spectral band operation of CHARA, our goal is to resolve orbits of short-period binaries and develo…
Interferometric Survey of Stellar Parameters: Towards homogeneous FGK stars parameters and surface-brightness color relation in the context of PLATO space mission
Romina V. Ibañez Bustos, Denis Mourard, Nicolas Nardetto +20
The estimation of stellar angular diameters can be performed from the surface brightness - color relation (SBCR) and photometry. The SBCR have been considered by the PLATO space mi…
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…
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…
The orbital parameters of the del Cep inner binary system determined using 2019 HARPS-N spectroscopic data
N. Nardetto, V. Hocdé, P. Kervella +11
An inner companion has recently been discovered orbiting the prototype of classical Cepheids, delta Cep, whose orbital parameters are still not fully constrained. We collected new…
