High-Angular-Resolution Survey of Stars within 18 pc of the Sun: Part I
F. Carolina Rojas-Galindo, Valeri G. Orlov, Rene A. Mendez +1
We present the rationale, design, methodology, and observational facilities of a high-angular-resolution imaging survey of stars within 18~pc of the Sun. Our comprehensive sample c…
Speckle Interferometry at SOAR in 2024 and 2025
Andrei Tokovinin, Brian D. Mason, Rene A. Mendez +1
Results of speckle interferometry observations at the 4.1 m SOuthern Astrophysical Research (SOAR) telescope obtained during 2024-2025 are presented. We present 5316 measurements o…
Spitzer + HST parallaxes of 13 late T and Y dwarfs
Federico Marocco, J. Davy Kirkpatrick, Richard L. Smart +13
We present astrometric measurements for 13 cold brown dwarfs in the solar neighborhood (d < 20pc). By combining archival Spitzer data with our own Hubble Space Telescope (HST) obse…
Southern binaries with the Zorro Speckle Camera @ Gemini-South
Rene A. Mendez, Andrei Tokovinin, Edgardor Costa +1
We present measurements in the context of a survey of southern hemisphere binary and multiple stellar systems observed with the Zorro Speckle dual diffraction-limited optical imagi…
Speckle Interferometry at SOAR in 2023
Andrei Tokovinin, Brian D. Mason, Rene A. Mendez +1
Results of the speckle-interferometry observations at the 4.1 m Southern Astrophysical Research Telescope (SOAR) obtained during 2023 are presented: 1913 measurements of 1533 resol…
Mass ratio of single-line spectroscopic binaries with visual orbits using Bayesian inference and suitable priors
Jennifer Anguita-Aguero, Rene A. Mendez, Miguel Videla +4
We present orbital elements for twenty-two single-line binaries, nine of them studied for the first time, determined from a joint spectroscopic and astrometric solution. The astrom…
