Circumstellar emission of Cepheids across the instability strip: Mid-infrared observations with VLTI/MATISSE

V. Hocdé, A. Matter, N. Nardetto +14

The circumstellar envelopes (CSE) of Cepheids are still not well characterized despite their potential impact on distance determination via both the period-luminosity relation and…

The Infrared Surface Brightness technique applied to RR Lyrae stars from the solar neighborhood

Bartłomiej Zgirski, Wolfgang Gieren, Grzegorz Pietrzyński +9

The Baade-Wesselink method allows us to estimate distances to individual pulsating stars. Accurate geometric parallaxes obtained by the Gaia mission serve us in the calibration of…

The Orbit and Dynamical Mass of Polaris: Observations with the CHARA Array

Nancy Remage Evans, Gail Schaefer, Alexandre Gallenne +19

The 30 year orbit of the Cepheid Polaris has been followed with observations by the CHARA Array (Center for High Angular Resolution Astronomy) from 2016 through 2021. An additional…

Projection factor and radii of Type II Cepheids

Piotr Wielgórski, Grzegorz Pietrzyński, Wolfgang Gieren +14

Type II Cepheids are old pulsating stars that can be used to trace the distribution of an old stellar population and to measure distances to globular clusters and galaxies within s…

The orbital parameters of the del Cep inner binary system determined using 2019 HARPS-N spectroscopic data

N. Nardetto, V. Hocdé, P. Kervella +11

An inner companion has recently been discovered orbiting the prototype of classical Cepheids, delta Cep, whose orbital parameters are still not fully constrained. We collected new…

The Baade-Wesselink projection factor of RR Lyrae stars -- Calibration from OHP/SOPHIE spectroscopy and Gaia DR3 parallaxes

Garance Bras, Pierre Kervella, Boris Trahin +10

The application of the parallax of pulsation (PoP) technique to determine distances of pulsating stars implies the use of a scaling parameter, the projection factor (p-factor), req…
