The Herculis system solved after nearly three centuries
Marcus L. Marcussen, Mikkel N. Lund, Frank Grundahl +11
Herculis is a bright, nearby quadruple system. Its brightest member, Her Aa, displays solar-like oscillations, establishing the system as a crucial benchmark for asterose…
TOI-1333Ab is on a well-aligned orbit. An aligned hot Jupiter around an F-type star with a mutually inclined stellar companion
E. Knudstrup, M. L. Marcussen, S. H. Albrecht +2
Spin-orbit obliquity measurements of hot-Jupiter systems constrain giant planet migration and tidal evolution. In binary systems, combining stellar obliquities with the orbit-orbit…
Astrometry and Precise Radial Velocities Yield a Complete Orbital Solution for the Nearby Eccentric Brown Dwarf LHS 1610 b
Evan Fitzmaurice, Gudmundur Stefánsson, Robert D. Kavanagh +18
The LHS 1610 system consists of a nearby ( pc) M5 dwarf hosting a candidate brown dwarf companion in a day, eccentric () orbit. We confirm this brown dwa…
Gaia-4b and 5b: Radial Velocity Confirmation of Gaia Astrometric Orbital Solutions Reveal a Massive Planet and a Brown Dwarf Orbiting Low-mass Stars
Gudmundur Stefansson, Suvrath Mahadevan, Joshua Winn +31
Gaia astrometry of nearby stars is precise enough to detect the tiny displacements induced by substellar companions, but radial velocity data are needed for definitive confirmation…
