An Intermediate-orbit Brown Dwarf Confirmed with Astrometry+Radial Velocity Joint Analysis, and the Eccentricity Distribution of Brown Dwarfs Across Different Locations
Lei Ren, Tianjun Gan, Yifan Xuan +5
Intermediate-orbit ( AU) brown dwarfs with absolute mass measurements are essential for understanding the evolution of substellar objects. Although such systems remain rare…
Transiting Planetary Systems with Distant Giant Companions Remain Moderately Coplanar
Guang-Yao Xiao, Huan-Yu Teng, Xiumin Huang +4
The mutual inclination between inner planets and distant giant companions provides an important probe of planetary system formation and dynamical evolution, yet direct measurements…
Unveiling the nature of G6096: a likely hierarchical triple system
Yinghao Xu, Xinlin Zhao, Song Wang +10
G6096 (Gaia DR3 609651611028044544) was recently reported as a wide ( days) and eccentric () binary possibly hosting a massive white dwarf or neutron star. In…
The 3D Architecture of a pair of 6:1 Resonant Brown Dwarfs around the Naked-eye star Ophiuchi
Tianshenhong Sang, Guang-Yao Xiao, Ying-Yi Cao +8
We present a revisiting study of the brown dwarf pair orbiting the naked-eye () K-giant ~Ophiuchi, located only 44\,pc from our Solar system. By jointly analysing archiva…
Cold giant discoveries from a joint radial-velocity and astrometry framework
Pablo A. Peña, James S. Jenkins, Fabo Feng +11
The population of long-period giant planets shapes planetary system architectures and formation pathways, but these cold Jupiters remain relatively unexplored. Radial velocity (RV)…
A universal brown dwarf desert formed between planets and stars
Kaiming Cui, Guang-Yao Xiao, Fabo Feng +10
Giant planets and brown dwarfs play a crucial role in star and planet formation, as they are situated at the boundary between planets and stars with uncertain formation mechanisms.…
HD 164604 c: a second giant planet on a 15-yr orbit and the constraint of the planet-planet mutual inclination
Guang-Yao Xiao, Fabo Feng, R. Paul Butler +4
We report the discovery of a new massive giant planet, HD 164604 c ( au, and or $7.6_{-1.0}…
RVTESS I: Modeling Asteroseismic Signals with Simultaneous Photometry and RVs
Jiaxin Tang, Sharon X. Wang, Yaguang Li +22
Detecting small planets via the radial velocity method remains challenged by signals induced by stellar variability, versus the effects of the planet(s). Here, we explore using Gau…
Detection of four cold Jupiters through combined analyses of radial velocity and astrometry data
Yiyun Wu, Guang-Yao Xiao, R. Paul Butler +19
Cold Jupiters play a crucial role in planet formation and dynamical evolution. Since their initial discovery around 47 UMa, they have attracted significant interest, yet their form…
Detection of dark companions via the combination of eclipse timing variation, Hipparcos and/or Gaia astrometry: the cases of V Puppis and CY Ari
Guang-Yao Xiao, Fabo Feng, Song Wang +3
The third body is expected to shape the formation and evolution of close binary systems. In this work, we develop a method to detect and characterize the tertiary companion around…
Updated Mutual Inclination Measurement for 14 Her b and c
Guang-Yao Xiao, Fabo Feng
The mutual inclination between orbits within multi-planetary systems is difficult to measure directly. Through a joint analysis of RVs, Hipparcos-Gaia absolute astrometry and r…
A Cartesian catalog of 30 million Gaia sources based on second-order and Monte Carlo error propagation
Luyao Zhang, Fabo Feng, Yicheng Rui +2
Accurate measurements of stellar positions and velocities are crucial for studying galactic and stellar dynamics. We aim to create a Cartesian catalog from Gaia DR3 to serve as a h…
Lessons learned from the detection of wide companions by radial velocity and astrometry
Fabo Feng, Guang-Yao Xiao, Hugh R. A. Jones +3
The detection and constraint of the orbits of long-period giant planets is essential for enabling their further study through direct imaging. Recently, it has been highlighted that…
HD 222237 b: a long period super-Jupiter around a nearby star revealed by radial-velocity and Hipparcos-Gaia astrometry
Guang-Yao Xiao, Fabo Feng, Stephen A. Shectman +16
Giant planets on long period orbits around the nearest stars are among the easiest to directly image. Unfortunately these planets are difficult to fully constrain by indirect metho…
Tianyu: search for the second solar system and explore the dynamic universe
Fabo Feng, Yicheng Rui, Zhimao Du +32
Giant planets like Jupiter and Saturn, play important roles in the formation and habitability of Earth-like planets. The detection of solar system analogs that have multiple cold g…
