The origin of hydrogen line emission for five Herbig Ae/Be stars spatially resolved by VLTI/AMBER spectro-interferometry
S. Kraus, K. -H. Hofmann, M. Benisty +14
To trace the accretion and outflow processes around YSOs, diagnostic spectral lines such as the BrG 2.166 micron line are widely used, although due to a lack of spatial resolution,…
VLTI monitoring of the dust formation event of the Nova V1280 Sco
Olivier Chesneau, Dipankar Banerjee, F. Millour +13
We present the first high spatial resolution monitoring of the dust forming nova V1280 Sco performed with the Very Large Telescope Interferometer (VLTI). Spectra and visibilities w…
High resolution spectroscopy for Cepheids distance determination. III. A relation between gamma-velocities and gamma-asymmetries
N. Nardetto, A. Stoekl, D. Bersier +1
Galactic Cepheids in the vicinity of the Sun have a residual line-of-sight velocity, or gamma-velocity, which shows a systematic blueshift of about 2 km/s compared to an axisymmetr…
High resolution spectroscopy for Cepheids distance determination. II. A period- projection factor relation
N. Nardetto, D. Mourard, Ph. Mathias +2
The projection factor is a key quantity for the interferometric Baade-Wesselink (hereafter IBW) and surface-brightness (hereafter SB) methods of determining the distance of Cepheid…
High resolution spectroscopy for Cepheids distance determination. I. Line asymmetry
N. Nardetto, D. Mourard, P. Kervella +3
The ratio of pulsation to radial velocity (the projection factor) is currently limiting the accuracy of the interferometric Baade-Wesselink method. This work aims at establishing a…
A new calibration of Galactic Cepheid Period-Luminosity relations from B to K bands, and a comparison to LMC PL relations
P. Fouque, P. Arriagada, J. Storm +8
The universality of the Cepheid Period-Luminosity relations has been under discussion since metallicity effects have been assumed to play a role in the value of the intercept and,…
