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…
CHARA/SPICA: The six-telescope visible combiner and near-infrared fringe tracker for the CHARA Array
D. Mourard, P. Bério, C. Bailet +43
The suite called Stellar Parameters and Images with a Cophased Array (SPICA) has two interferometric instruments installed at the focus of the CHARA Array located at Mount Wilson,…
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…
Monitoring fast solar chromospheric activity: the MeteoSpace project
Jean-Marie Malherbe, Thierry Corbard, Gaële Barbary +4
We present in this reference paper an instrumental project dedicated to the monitoring of solar activity during solar cycle 25. It concerns the survey of fast evolving chromospheri…
CHARA/SPICA: a 6-telescope visible instrument for the CHARA Array
Denis Mourard, Philippe Berio, Cyril Pannetier +25
With a possible angular resolution down to 0.1-0.2 millisecond of arc using the 330 m baselines and the access to the 600-900 nm spectral domain, the CHARA Array is ideally configu…
Progress on the calibration of surface brightness-color relations for early- and late-type stars
Anthony Salsi, Nicolas Nardetto, Denis Mourard +8
Surface brightness-color relations (SBCRs) are used for estimating angular diameters and deriving stellar properties. They are critical to derive extragalactic distances of early-t…
Precise calibration of the dependence of surface brightness-colour relations on colour and class for late-type stars
A. Salsi, N. Nardetto, D. Mourard +9
Surface brightness-colour relations (SBCRs) are used to derive the stellar angular diameters from photometric observations. They have various astrophysical applications, such as th…
Calibrating the surface brightness - color relation for late-type red giants stars in the visible domain using VEGA/CHARA interferometric observations
N. Nardetto, A. Salsi, D. Mourard +14
The surface brightness - color relationship (SBCR) is a poweful tool for determining the angular diameter of stars from photometry. It was for instance used to derive the distance…
Optical interferometry and Gaia measurement uncertainties reveal the physics of asymptotic giant branch stars
A. Chiavassa, K. Kravchenko, F. Millour +20
Context. Asymptotic giant branch stars are cool luminous evolved stars that are well observable across the Galaxy and populating Gaia data. They have complex stellar surface dynami…
From the stellar properties of HD219134 to the internal compositions of its transiting exoplanets
Roxanne Ligi, Caroline Dorn, Aurélien Crida +8
The harvest of exoplanet discoveries has opened the area of exoplanet characterisation. But this cannot be achieved without a careful analysis of the host star parameters. The syst…
MISOLFA solar monitor for the ground PICARD program
T. Corbard, A. Irbah, P. Assus +5
Developed at the Observatoire de la Côte d'Azur (OCA) within the framework of the PICARD space mission (Thuillier et al., 2006) and with support from the french spatial agency (CNE…
On the importance of astronomical refraction for modern Solar astrometric measurements
T. Corbard, R. Ikhlef, F. Morand +2
In this work we study in details the influence of pure astronomical refraction on solar metrologic measurements made from ground-based full disk imagery and provide the tools for c…
PICARD SODISM, a space telescope to study the Sun from the middle ultraviolet to the near infrared
M. Meftah, J. -F. Hochedez, A. Irbah +25
The Solar Diameter Imager and Surface Mapper (SODISM) on board the PICARD space mission provides wide-field images of the photosphere and chromosphere of the Sun in five narrow pas…
