CHARA Array Observations of the Evolved Components in Symbiotic Star Systems

Thomas Martin Gaudin, Ryan Norris, Magdalena Otulakowska-Hypka +30

The nature of the mechanisms that drive mass transfer in symbiotic stars remains an area of active research in stellar astronomy. Constraining the role that both stellar winds and…

Empirical H- and K-band Limb Darkening for 31 CHARA Stars: A Near-Infrared Benchmark for Stellar-Atmosphere Models

Narsireddy Anugu, John D. Monnier, Antoine Mérand +9

Limb darkening, the decrease in stellar intensity from the disk center to the limb, encodes the temperature structure and opacity of stellar atmospheres. Direct spatially resolved…

Pre-nova Observations of T CrB: A view from the CHARA Array

Ryan Norris, Narsireddy Anugu, Thomas Gaudin +38

T CrB is a symbiotic recurrent nova consisting of a red giant and white dwarf with recent eruptions in 1866 and 1946 and an anticipated eruption in the mid 2020s. We report CHARA A…

Multiplicity of Galactic Cepheids from long-baseline interferometry V. High-accuracy orbital parallax and mass of SU Cygni

A. Gallenne, N. R. Evans, P. Kervella +23

Cepheid masses are particularly necessary to help solving the mass discrepancy, while independent distance determinations provide crucial test of the period-luminosity relation and…

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…

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…
