Toward a renewed Galactic Cepheid distance scale from Gaia and optical interferometry
Pierre Kervella, Antoine Mérand, Alexandre Gallenne +9
Through an innovative combination of multiple observing techniques and mod- eling, we are assembling a comprehensive understanding of the pulsation and close environment of Cepheid…
Observational calibration of the projection factor of Cepheids - III. The long-period Galactic Cepheid RS Puppis
Pierre Kervella, Boris Trahin, Howard E. Bond +10
The projection factor (p-factor) is an essential component of the classical Baade-Wesselink (BW) technique, that is commonly used to determine the distances to pulsating stars. It…
VEGA/CHARA interferometric observations of Cepheids. I. A resolved structure around the prototype classical Cepheid delta Cep in the visible spectral range
N. Nardetto, A. Mérand, D. Mourard +23
The B-W method is used to determine the distance of Cepheids and consists in combining the angular size variations of the star, as derived from infrared surface-brightness relation…
Observational calibration of the projection factor of Cepheids. II. Application to nine Cepheids with HST/FGS parallax measurements
Joanne Breitfelder, Antoine Mérand, Pierre Kervella +4
The distance to pulsating stars is classically estimated using the parallax-of-pulsation (PoP) method, which combines spectroscopic radial velocity measurements and angular diamete…
Cepheid distances from the SpectroPhoto-Interferometry of Pulsating Stars (SPIPS) - Application to the prototypes delta Cep and eta Aql
Antoine Merand, Pierre Kervella, Joanne Breitfelder +8
The parallax of pulsation, and its implementations such as the Baade-Wesselink method and the infrared surface bright- ness technique, is an elegant method to determine distances o…
Robust high-contrast companion detection from interferometric observations. The CANDID algorithm and an application to six binary Cepheids
A. Gallenne, A. Mérand, P. Kervella +15
Long-baseline interferometry is an important technique to spatially resolve binary or multiple systems in close orbits. By combining several telescopes together and spectrally disp…
