Interferometric detections of sdO companions orbiting three classical Be stars
R. Klement, G. H. Schaefer, D. R. Gies +17
Classical Be stars are possible products of close binary evolution, in which the mass donor becomes a hot, stripped O or B-type subdwarf (sdO/sdB), and the mass gainer spins up and…
EXPRES. III. Revealing the Stellar Activity Radial Velocity Signature of Eridani with Photometry and Interferometry
Rachael M. Roettenbacher, Samuel H. C. Cabot, Debra A. Fischer +20
The distortions of absorption line profiles caused by photospheric brightness variations on the surfaces of cool, main-sequence stars can mimic or overwhelm radial velocity (RV) sh…
Establishing Oph as a Prototype Rotator: Precision Orbit with new Keck, CHARA, and RV Observations
Tyler Gardner, John D. Monnier, Francis C. Fekel +11
Alpha Ophiuchi (Rasalhague) is a nearby rapidly rotating A5IV star which has been imaged by infrared interferometry. Oph is also part of a known binary system, with a companion…
Gem: a hierarchical triple system with an outer Be star
Robert Klement, Petr Hadrava, Thomas Rivinius +17
Time series of spectroscopic, speckle-interferometric, and optical long-baseline-interferometric observations confirm that Gem is a hierarchical triple system. It consists of a…
Constraining the Nature of the PDS 70 Protoplanets with VLTI/GRAVITY
J. J. Wang, A. Vigan, S. Lacour +101
We present K-band interferometric observations of the PDS 70 protoplanets along with their host star using VLTI/GRAVITY. We obtained K-band spectra and 100 as precision astromet…
The ExoGRAVITY project: using single mode interferometry to characterize exoplanets
S. Lacour, J. J. Wang, M. Nowak +89
Combining adaptive optics and interferometric observations results in a considerable contrast gain compared to single-telescope, extreme AO systems. Taking advantage of this, the E…
