Pulsating chromosphere of classical Cepheids. Calcium infrared triplet and H profile variations
V. Hocdé, N. Nardetto, S. Borgniet +10
It has been shown recently that the infrared emission of Cepheids, which is constant over the pulsation cycle, might be due to a pulsating shell of ionized gas of about 15\% of the…
Optical interferometry and Gaia measurement uncertainties reveal the physics of asymptotic giant branch stars
A. Chiavassa, K. Kravchenko, F. Millour +20
Context. Asymptotic giant branch stars are cool luminous evolved stars that are well observable across the Galaxy and populating Gaia data. They have complex stellar surface dynami…
The Leavitt law of Milky Way Cepheids from Gaia DR2 static companion parallaxes
Louise Breuval, Pierre Kervella, Frédéric Arenou +13
Classical Cepheids (CCs) are at the heart of the empirical extragalactic distance ladder. Milky Way CCs are the only stars of this class accessible to trigonometric parallax measur…
A thin shell of ionized gas explaining the IR excess of classical Cepheids
V. Hocdé, N. Nardetto, E. Lagadec +12
Despite observational evidences, InfraRed (IR) excess of classical Cepheids are seldom studied and poorly understood, but probably induces systematics on the Period-Luminosity (PL)…
Consistent radial velocities of classical Cepheids from the cross-correlation technique
Simon Borgniet, Pierre Kervella, Nicolas Nardetto +11
Accurate radial velocities () of Cepheids are mandatory within the context of distance measurements via the Baade-Wesselink technique. The most common de…
Towards final characterisation and performance of the GCT prototype telescope structure for the Cherenkov Telescope Array
Oriane Le Blanc, Gilles Fasola, Jean-Laurent Dournaux +12
The Gamma-ray Cherenkov Telescope (GCT) is an innovative dual-mirror solution proposed for the Small Size Telescopes of the future Cherenkov Telescope Array (CTA), capable of imagi…
