V659 Cen: System Parameters Updated
Nancy Remage Evans, Charles Proffitt, Pierre Kervella +8
V659 Cen is a classical Cepheid which is part of a multiple system. Previous observations have shown that a hot companion dominates an ultraviolet spectrum and a cooler main sequen…
Mass of Cepheid V350 Sgr Incorporating Interferometry and the Companion Mass
Nancy Remage Evans, Alexandre Gallenne, Pierre Kervella +8
The system V350 Sgr has a classical Cepheid for the primary. Interferometry is presented for the system and the full orbit is determined. The mass of the companion has been determi…
The Components of Cepheid Systems: The FN Vel System
Nancy Remage Evans, Pierre Kervella, Joanna Kuraszkiewicz +8
Cepheid masses continue to be important tests of evolutionary tracks for intermediate mass stars as well as important predictors of their future fate. For systems where the seconda…
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…
The Orbit and Mass of the Cepheid AW Per
Nancy Remage Evans, Alexandre Gallenne, Pierre Kervella +17
The Cepheid AW Per is a component in a multiple system with a long period orbit. The radial velocities of Griffin (2016) cover the 38 year orbit well. An extensive program of inter…
Hubble Space Telescope Snapshot Survey for Resolved Companions of Galactic Cepheids: Final Results
Nancy Remage Evans, H. Moritz Guenther, Howard E. Bond +13
Cepheids in multiple systems provide information on the outcome of the formation of massive stars. They can also lead to exotic end-stage objects. This study concludes our survey o…
A geometrical 1% distance to the short-period binary Cepheid V1334 Cygni
A. Gallenne, P. Kervella, N. R. Evans +18
Cepheid stars play a considerable role as extragalactic distances indicators, thanks to the simple empirical relation between their pulsation period and their luminosity. They over…
Multiplicity of Galactic Cepheids from long-baseline interferometry~III. Sub-percent limits on the relative brightness of a close companion of ~Cephei
A. Gallenne, A. Merand, P. Kervella +11
We report new CHARA/MIRC interferometric observations of the Cepheid archetype Cep, which aimed at detecting the newly discovered spectroscopic companion. We reached a maximum…
