Unveiling the nature of G6096: a likely hierarchical triple system
Yinghao Xu, Xinlin Zhao, Song Wang +10
The authors re‑examine the object G6096, previously thought to be a wide binary with a compact companion, and using spectroscopy, radial‑velocity and astrometric analysis together…
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…
