Multiplicity of Galactic Cepheids from long-baseline interferometry. IV. New detected companions from MIRC and PIONIER observations
A. Gallenne, P. Kervella, S. Borgniet +10
We aim at detecting and characterizing the main-sequence companions of a sample of known and suspected Galactic binary Cepheids. We used the multi-telescope interferometric combine…
A geometrical 1% distance to the short-period binary Cepheid V1334 Cygni
A. Gallenne, P. Kervella, N. R. Evans +18
Cepheid stars play a considerable role as extragalactic distances indicators, thanks to the simple empirical relation between their pulsation period and their luminosity. They over…
The effect of metallicity on Cepheid Period-Luminosity relations from a Baade-Wesselink analysis of Cepheids in the Milky Way and Magellanic Clouds
W. Gieren, J. Storm, P. Konorski +14
The extragalactic distance scale builds on the Cepheid period-luminosity (PL) relation. In this paper, we want to carry out a strictly differential comparison of the absolute PL re…
Shadows and asymmetries in the T Tauri disk HD 143006: Evidence for a misaligned inner disk
M. Benisty, A. Juhasz, S. Facchini +13
While planet formation is thought to occur early in the history of a protoplanetary disk, the presence of planets embedded in disks, or of other processes driving disk evolution, m…
CRIRES high-resolution infrared spectroscopy of the long-period Cepheid l Car
N. Nardetto, E. Poretti, A. Gallenne +17
The dynamical structure of the atmosphere of Cepheids has been well studied in the optical. Several authors have found very interesting spectral features in the J band, but little…
Optical interferometry and Gaia parallaxes for a robust calibration of the Cepheid distance scale
Pierre Kervella, Antoine Mérand, Alexandre Gallenne +5
We present the modeling tool we developed to incorporate multi-technique observations of Cepheids in a single pulsation model: the Spectro-Photo-Interferometry of Pulsating Stars (…
