Directly Determined Properties of HD 97658 from Interferometric Observations
Tyler G. Ellis, Tabetha Boyajian, Kaspar von Braun +5
We conducted interferometric observations with the CHARA Array of transiting super-Earth host HD 97658 and measured its limb-darkened angular diameter to be $θ_{\text{LD}}=0.314\pm…
Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
Calibrating the surface brightness - color relation for late-type red giants stars in the visible domain using VEGA/CHARA interferometric observations
N. Nardetto, A. Salsi, D. Mourard +14
The surface brightness - color relationship (SBCR) is a poweful tool for determining the angular diameter of stars from photometry. It was for instance used to derive the distance…
Optical interferometry and Gaia measurement uncertainties reveal the physics of asymptotic giant branch stars
A. Chiavassa, K. Kravchenko, F. Millour +20
Context. Asymptotic giant branch stars are cool luminous evolved stars that are well observable across the Galaxy and populating Gaia data. They have complex stellar surface dynami…
Visible and near-infrared spectro-interferometric analysis of the edge-on Be star Aquarii
E. S. G. de Almeida, A. Meilland, A. Domiciano de Souza +11
We present a detailed visible and near-IR spectro-interferometric analysis of the Be-shell star Aquarii from quasi-contemporaneous CHARA/VEGA and VLTI/AMBER observations. We me…
Exploring the RCrA environment with SPHERE: Discovery of a new stellar companion
D. Mesa, M. Bonnefoy, R. Gratton +39
Aims. R Coronae Australis (R CrA) is the brightest star of the Coronet nebula of the Corona Australis (CrA) star forming region. It has very red colors, probably due to dust absorp…
