Orbits of Twelve Multiple Stars
Andrei Tokovinin
Inner and outer orbits in twelve hierarchical stellar systems are determined using high-resolution speckle imaging, radial velocities, or both. Masses and fluxes of the components…
Spectroscopic Orbits of Subsystems in Multiple Stars. XI
Andrei Tokovinin
Adding to the large radial velocity survey of nearby solar-type stars (summary in Tokovinin, 2023a), spectroscopic orbits are determined for four hierarchical systems: HIP 49442 (i…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems III: Aperture Masking Interferometric Observations of the star HIP 65426 at 3.8 um
Shrishmoy Ray, Steph Sallum, Sasha Hinkley +121
We present aperture masking interferometry (AMI) observations of the star HIP 65426 at as a part of the JWST Direct Imaging Early Release Science (ERS) program obta…
Orbits of Six Triple Systems
Andrei Tokovinin
Joint analysis of position measurements and radial velocities of six triple stellar systems is conducted to determine their inner and/or outer orbits. Accumulation of such data is…
Searching for compact hierarchical triple systems candidates in astrometric binaries and accelerated solutions
Dolev Bashi, Andrei Tokovinin
Compact hierarchical triple (CHT) systems, where a tertiary component orbits an inner binary, provide critical insights into stellar formation and evolution. Despite their importan…
