Precision Orbit of Delphini and Prospects for Astrometric Detection of Exoplanets
Tyler Gardner, John D. Monnier, Francis C. Fekel +17
Combining visual and spectroscopic orbits of binary stars leads to a determination of the full 3D orbit, individual masses, and distance to the system. We present a full analysis o…
No Sun-like dynamo on the active star Andromedae from starspot asymmetry
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +12
Sunspots are cool areas caused by strong surface magnetic fields inhibiting convection. Moreover, strong magnetic fields can alter the average atmospheric structure, degrading our…
Resolving Vega and the inclination controversy with CHARA/MIRC
J. D. Monnier, Xiao Che, Ming Zhao +15
Optical and infrared interferometers definitively established that the photometric standard Vega (alpha Lyrae) is a rapidly rotating star viewed nearly pole-on. Recent independent…
First visual orbit for the prototypical colliding-wind binary WR 140
J. D. Monnier, Ming Zhao, E. Pedretti +14
Wolf-Rayet stars represent one of the final stages of massive stellar evolution. Relatively little is known about this short-lived phase and we currently lack reliable mass, distan…
Colder and Hotter: Interferometric imaging of β Cassiopeiae and α Leonis
X. Che, J. D. Monnier, M. Zhao +9
Near-infrared interferometers have recently imaged a number of rapidly rotating A-type stars, finding levels of gravity darkening inconsistent with theoretical expectations. Here,…
Imaging and Modeling Rapidly Rotating Stars: Alpha Cephei and Alpha Ophiuchi
M. Zhao, J. D. Monnier, E. Pedretti +10
We present sub-milliarcseond resolution imaging and modeling of two nearby rapid rotators Alpha Cephei and Alpha Ophiuchi, obtained with the CHARA array - the largest optical/IR in…
