C3PO III: On the Lithium Signatures Following Planet Engulfment by Stars
Qinghui Sun, Yuan-Sen Ting, Fan Liu +8
Planet engulfment has been identified as one of the mechanisms for enhancing lithium abundance in stars. However, comprehensive investigations into lithium signatures following suc…
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…
Understanding the Planetary Formation and Evolution in Star Clusters(UPiC)-I: Evidence of Hot Giant Exoplanets Formation Timescales
Yuan-Zhe Dai, Hui-Gen Liu, Jia-Yi Yang +1
Planets in young star clusters could shed light on planet formation and evolution since star clusters can provide accurate age estimation. However, the number of transiting planets…
Planets Across Space and Time (PAST). III. Morphology of the Planetary Radius Valley as a Function of Stellar Age and Metallicity in the Galactic Context Revealed by the LAMOST-Gaia-Kepler Sample
Di-Chang Chen, Ji Wei Xie, Ji-Lin. Zhou +7
The radius valley, a dip in the radius distribution of exoplanets at ~1.9 Earth radii separates compact rocky Super-Earths and Sub-Neptunes with lower density. Various hypotheses h…
Planets Across Space and Time (PAST). II: Catalog and Analyses of the LAMOST-Gaia-Kepler Stellar Kinematic Properties
Di-Chang Chen, Jia-Yi Yang, Ji-Wei Xie +10
The Kepler telescope has discovered over 4,000 planets (candidates) by searching ? 200,000 stars over a wide range of distance (order of kpc) in our Galaxy. Characterizing the kine…
Occurrence and Architecture of Kepler Planetary Systems as Functions of Stellar Mass and Effective Temperature
Jia-Yi Yang, Ji-Wei Xie, Ji-Lin Zhou
The Kepler mission has discovered thousands of exoplanets around various stars with different spectral types (M, K, G, and F) and thus different masses and effective temperatures.…
A power law decay evolution scenario for polluted single white dwarfs
Di-Chang Chen, Ji-Lin Zhou, Ji-Wei Xie +6
Planetary systems can survive the stellar evolution, as evidenced by the atmospheric metal pollution and dusty disks of single white dwarfs. Recent observations show that 1 to 4 pe…
Planetary Transit Candidates in the CSTAR Field: Analysis of the 2008 Data
Songhu Wang, Hui Zhang, Ji-Lin Zhou +26
The Chinese Small Telescope ARray (CSTAR) is a group of four identical, fully automated, static 14.5 cm telescopes. CSTAR is located at Dome A, Antarctica and covers 20 square degr…
Eight Planets in Four Multi-planet Systems via Transit Timing Variations in 1350 Days
Ming Yang, Hui-Gen Liu, Hui Zhang +1
Analysis of the transit timing variations (TTVs) of candidate pairs near mean-motion resonances (MMRs) is an effective method to confirm planets. Hitherto, 68 planets in 34 multi-p…
