Constraints on the formation history and composition of Kepler planets from their distribution of orbital period ratios
Di-Chang Chen, Christoph Mordasini, Ji-Wei Xie +2
The Kepler high-precision planetary sample has revealed a radius valley, separating compact super-Earths from sub-Neptunes with lower density. Super-Earths are generally assumed to…
Reconstructing Intrinsic Stellar Noise with Stellar Atmospheric Parameters and Chromospheric Activity
Jinghua Zhang, Maosheng Xiang, Jie Yu +9
Accurately characterizing intrinsic stellar photometric noise induced by stellar astrophysics, such as stellar activity, granulation, and oscillations, is of crucial importance for…
Planets Across Space and Time (PAST). V. The evolution of hot Jupiters revealed by the age distribution of their host stars
Di-Chang Chen, Ji-Wei Xie, Ji-Lin Zhou +11
The unexpected discovery of hot Jupiters challenged the classical theory of planet formation inspired by our solar system. Until now, the origin and evolution of hot Jupiters are s…
Planets Across Space and Time (PAST) IV: The Occurrence and Architecture of Kepler Planetary Systems as a Function of Kinematic Age Revealed by the LAMOST-Gaia-Kepler Sample
Jia-Yi Yang, Di-Chang Chen, Ji-Wei Xie +7
One of the fundamental questions in astronomy is how planetary systems form and evolve. Measuring the planetary occurrence and architecture as a function of time directly addresses…
Global Instability of Exo-Moon System Triggered by Photo-Evaporation
Ming Yang, Ji-Wei Xie, Ji-Lin Zhou +2
Many exoplanets have been found in orbits close to their host stars and thus they are subject to the effects of photo-evaporation. Previous studies have shown that a large portion…
Exoplanet Orbital Eccentricities Derived From LAMOST-Kepler Analysis
Ji-Wei Xie, Subo Dong, Zhaohuan Zhu +14
The nearly circular (mean eccentricity <e>~0.06) and coplanar (mean mutual inclination <i>~3 deg) orbits of the Solar System planets motivated Kant and Laplace to put forth the hyp…
