X-rays in Cepheids: XMM-Newton Observations of Aql

Nancy Remage Evans, Ignazio Pillitteri, Pierre Kervella +13

X-ray bursts have recently been discovered in the Cepheids Cep and Dor modulated by the pulsation cycle. We have obtained an observation of the Cepheid Aql with the XMM…

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…

Evidence of a substellar companion to AB Dor C

J. B. Climent, J. P. Berger, J. C. Guirado +5

Studies of fundamental parameters of very low-mass objects are indispensable to provide tests of stellar evolution models that are used to derive theoretical masses of brown dwarfs…

The Araucaria Project: High-precision orbital parallax and masses of eclipsing binaries from infrared interferometry

A. Gallenne, G. Pietrzyński, D. Graczyk +9

Context. The precise determinations of stellar mass at 1% provide important constraints on stellar evolution models. Accurate parallax measurements can also serve as independ…
