Nardetto, N.; Salsi, A.; Mourard, D.; Hocdé, V.; Perraut, K.; Gallenne, A.; Mérand, A.; Graczyk, D.; Pietrzynski, G.; Gieren, W.; Kervella, P.; Ligi, R.; Meilland, A.; Morand, F.; Stee, P.; Tallon-Bosc, I.; Brummelaar, T. ten (EDP Science, 2020)Context. 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 of eclipsing binaries in the Large ...

Breitfelder, J.; Mérand, A.; Kervella, Pierre; Gallenne, A.; Szabados, L.; Anderson, R. I.; Le Bouquin, J.-B. (ESO, 2016-03)Context. The distance to pulsating stars is classically estimated using the parallax-of-pulsation (PoP) method, which combines spectroscopic radial velocity (RV) measurements and angular diameter (AD) estimates to derive ...

Kervella, P.; Mérand, A.; Ledoux, C.; Demory, B.-O.; Le Bouquin, J.-B. (EDP Sciences, 2016)The nearby red dwarf binary GJ65 AB (UV + BL Ceti, M5.5Ve + M6Ve) is a cornerstone system to probe the physics of very low-mass stars. The radii of the two stars are currently known only from indirect photometric estimates, ...

Nardetto, N.; Mérand, A.; Mourard, D.; Storm, J.; Gieren, W.; Fouqué, P.; Graczyk, D.; Kervella, P.; Neilson, H.; Pietrzynski, G.; Pilecki, B.; Breitfelder, J.; Berio, P.; Challouf, M.; Clausse, J.-M.; Ligi, R.; Mathias, P.; Meilland, A.; Perraut, K.; Poretti, E.; Rainer, M.; Spang, A.; Stee, P.; Tallon-Bosc, I.; Brummelaar, T. ten (EDP Sciences, 2016)Context. 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 relations or interferometry, with its ...
