Diameters and Temperatures VII: High-angular resolution measurements of Solar-type stars with the CHARA Array
Tabetha S. Boyajian, Ashley A. Elliott, Emelly D. Tiburcio +8
We present interferometric measurements of angular diameters for 27 nearby solar-type stars obtained with the Precision Astronomical Visible Observations (PAVO) beam combiner at th…
The Periastron Passage of T Tauri South B as Viewed by ALMA: Millimeter Flux Variations and Dust Heating Triggered by Orbital Motion
Tracy L. Beck, Stephane Guilloteau, Gail Schaefer +3
We present 225 and 350 GHz imaging of the iconic T Tauri system using the Atacama Large Millimeter submillimeter Array (ALMA). T Tauri is a hierarchical triple system, and the clos…
Benchmarking Substellar Evolutionary Models Using New Age Estimates for HD 4747 B and HD 19467 B
Charlotte M. Wood, Tabetha Boyajian, Kaspar von Braun +5
Constraining substellar evolutionary models (SSEMs) is particularly difficult due to a degeneracy between the mass, age, and luminosity of a brown dwarf. In cases where a brown dwa…
Angular Sizes and Effective Temperatures of O-type Stars from Optical Interferometry with the CHARA Array
Kathryn D. Gordon, Douglas R. Gies, Gail H. Schaefer +3
We present interferometric observations of six O-type stars that were made with the Precision Astronomical Visible Observations (PAVO) beam combiner at the Center for High Angular…
The Sirius System and its Astrophysical Puzzles: Hubble Space Telescope and Ground-Based Astrometry
Howard E. Bond, Gail H. Schaefer, Ronald L. Gilliland +11
Sirius, the seventh-nearest stellar system, is a visual binary containing the metallic-line A1 V star Sirius A, brightest star in the sky, orbited in a 50.13-year period by Sirius…
Refined masses and distance of the young binary Haro 1-14 C
Jean-Baptiste Le Bouquin, J. -L. Monin, Jean-Philippe Berger +3
We aim to refine the dynamical masses of the individual component of the low-mass pre-main sequence binary Haro 1-14 C. We combine the data of the preliminary orbit presented previ…
Orbital and Evolutionary Constraints on the Planet Hosting Binary GJ 86 from the Hubble Space Telescope
J. Farihi, Howard E. Bond, P. Dufour +5
This paper presents new observations of the planet-hosting, visual binary GJ 86 (HR 637) using the Hubble Space Telescope. Ultraviolet and optical imaging with WFC3 confirms the st…
Spectral Energy Distributions of Be and Other Massive Stars
Y. Touhami, N. D. Richardson, D. R. Gies +7
We present spectrophotometric data from 0.4 to 4.2 microns for bright, northern sky, Be stars and several other types of massive stars. Our goal is to use these data with ongoing,…
