Paving the Road to the Habitable Worlds Observatory with High-Resolution Imaging I: New and Archival Speckle Observations of Potential HWO Target Stars
Zachary D. Hartman, Catherine A. Clark, Michael B. Lund +15
One of the key goals of the Habitable Worlds Observatory (HWO) is to directly image about 25 potentially habitable exoplanets and determine their properties. This challenge will re…
A search for Be stars in multiple systems within the solar neighborhood
V. M. Kalari, R. Salinas, C. Saez-Carvajal +9
Be stars are widely considered to be the product of binary interaction. However, whether all Be stars are formed via binary interaction is unclear, and detailed estimates of the mu…
High-Resolution Imaging of a TESS Control Sample: Verifying a Deficit of Close-In Stellar Companions to Exoplanet Host Stars
Colin Littlefield, Steve B. Howell, David R. Ciardi +6
The large number of exoplanets discovered with the Transiting Exoplanet Survey Satellite (TESS) means that any observational biases from TESS could influence the derived stellar mu…
Visual Orbits & Alignments of Planet Hosting Binary Systems
Kathryn Lester, Steve Howell, Rachel Matson +7
Roughly half of Solar-type planet hosts have stellar companions, so understanding how these binary companions affect the formation and evolution of planets is an important componen…
Speckle Observations of TESS Exoplanet Host Stars. II. Stellar Companions at 1-1000 AU and Implications for Small Planet Detection
Kathryn V. Lester, Rachel A. Matson, Steve B. Howell +7
We present high angular resolution imaging observations of 517 host stars of TESS exoplanet candidates using the `Alopeke and Zorro speckle cameras at Gemini North and South. The s…
Visual Orbits of Spectroscopic Binaries with the CHARA Array. III. HD 8374 and HD 24546
Kathryn V. Lester, Francis C. Fekel, Matthew Muterspaugh +9
We present the visual orbits of two long period spectroscopic binary stars, HD 8374 and HD 24546, using interferometric observations acquired with the CHARA Array and the Palomar T…
