Mid-infrared circumstellar emission of the long-period Cepheid l Carinae resolved with VLTI/MATISSE
V. Hocdé, N. Nardetto, A. Matter +149
The nature of circumstellar envelopes (CSE) around Cepheids is still a matter of debate. The physical origin of their infrared (IR) excess could be either a shell of ionized gas, o…
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…
The Milky Way Cepheid Leavitt law based on Gaia DR2 parallaxes of companion stars and host open cluster populations
Louise Breuval, Pierre Kervella, Richard I. Anderson +12
Classical Cepheids provide the foundation for the empirical extragalactic distance ladder. Milky Way Cepheids are the only stars in this class accessible to trigonometric parallax…
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)…
