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…

Segmented-Polynomial-fitting Least Squares (SPLS): An optimized algorithm to find Earth twins

Shuyue Zheng, Fabo Feng, Yicheng Rui

Detecting Earth twins remains challenging because their shallow, long-period transits are difficult to distinguish from background noise. Motivated by the challenge, we developed S…

A Population Synthesis Study on the Formation of Cold Jupiters from Truncated Planetesimal Disks

Kangrou Guo, Masahiro Ogihara, Shigeru Ida +3

The occurrence rate of giant planets increases with orbital period and turns over at a location that roughly corresponds to the snow line of solar-type stars. Further, the density…
