Multiplicity of Galactic Cepheids from long-baseline interferometry. II. The Companion of AX Circini revealed with VLTI/PIONIER
A. Gallenne, A. Mérand, P. Kervella +6
Aims: We aim at detecting and characterizing the main-sequence companion of the Cepheid AX Cir ( 18 yrs). The long-term objective is to estimate the mass of b…
Anchors for the Cosmic Distance Scale: the Cepheids U Sgr, CF Cas and CEab Cas
D. Majaess, G. Carraro, C. Moni Bidin +11
New and existing X-ray, UBVJHKsW(1-4), and spectroscopic observations were analyzed to constrain fundamental parameters for M25, NGC 7790, and dust along their sight-lines. The sta…
On the Form of the Spitzer Leavitt Law and its Dependence on Metallicity
D. Majaess, D. G. Turner, W. Gieren
The form and metallicity-dependence of Spitzer mid-infrared Cepheid relations are a source of debate. Consequently, Spitzer 3.6 and 4.5 um period-magnitude and period-color diagram…
Understanding the dynamical structure of pulsating stars: The center-of-mass velocity and the Baade-Wesselink projection factor of the beta-Cephei star alpha-Lupi
N. Nardetto, P. Mathias, A. Fokin +5
High-resolution spectroscopy of pulsating stars is a powerful tool to study the dynamical structure of their atmosphere. Lines asymmetry is used to derive the center-of-mass veloci…
Anchors for the Cosmic Distance Scale: the Cepheid QZ Normae in the Open Cluster NGC 6067
D. Majaess, L. Sturch, C. Moni Bidin +13
Cepheids are key to establishing the cosmic distance scale. Therefore it's important to assess the viability of QZ Nor, V340 Nor, and GU Nor as calibrators for Leavitt's law via th…
The Eclipsing Binary Cepheid OGLE-LMC-CEP-0227 in the Large Magellanic Cloud: pulsation modelling of light and radial velocity curves
M. Marconi, R. Molinaro, G. Bono +10
We performed a new and accurate fit of light and radial velocity curves of the Large Magellanic Cloud (LMC) Cepheid --OGLE-LMC-CEP-0227-- belonging to a detached double-lined eclip…
