Fates of the sub-stellar objects (FOSSO) II. Evidence for Suppression of Metal Pollution in White Dwarfs by Close Substellar Companions
Zhangliang Chen, Xin-Yue Zhang, Di-Chang Chen +4
Approximately 25--50\% of white dwarfs (WDs) exhibit metal absorption lines in their photospheres, interpreted as evidence of ongoing/recent accretion of planetary debris from remn…
Chemical Abundances Shape History (CASH). I. A Link between Giant Planets Orbital Periods and Host Stellar C/O Ratios
Ruisheng Zhang, Ji-Wei Xie, Mengrui Pan +5
The chemical abundance of host stars plays a pivotal role in shaping the formation history of planetary systems, yet the influence of elements beyond iron remains poorly understood…
How a Close-in Planet Protects its White Dwarf Host from Pollution
Xin-Yue Zhang, Ji-Wei Xie, Di-Chang Chen +1
Approximately 25-50% of white dwarfs (WDs) exhibit metal absorption lines in their photospheres, which are attributed to accretion from their remnant planetary systems. Although wh…
Planets Across Space and Time (PAST). VIII : Kinematic Characterization and Identification of Radial Velocity Variables for the LAMOST-Gaia-TESS Stars
Di Wu, Di-Chang Chen, Ji-Wei Xie +6
The Transiting Exoplanet Survey Satellite (TESS) has discovered over 6700 nearby exoplanets candidates using the transit method through its all-sky survey. Characterizing the kinem…
Planet Across Space and Time (PAST). VII. The origin and tidal evolution of hot Jupiters constrained by a broken age-frequency relation
Di-Chang Chen, Ji-Wei Xie, Ji-Lin Zhou +4
The discovery of hot Jupiters has challenged the classical planet formation theory. Although various formation mechanisms have been proposed, the dominant channel and relative cont…
The New Generation Planetary Population Synthesis (NGPPS) VIII. Impact of host star metallicity on planet occurrence rates, orbital periods, eccentricities, and radius valley morphology
Di-Chang Chen, Christoph Mordasini, Alexandre Emsenhuber +3
The dust-to-gas ratio in the protoplanetary disk, which is likely imprinted into the host star metallicity, is a property that plays a crucial role during planet formation. We aim…
Planets Across Space and Time (PAST). VI. Age Dependence of the Occurrence and Architecture of Ultra-Short-Period Planet Systems
Pei-Wei Tu, Ji-Wei Xie, Di-Chang Chen +1
Ultra-short-period (USP) planets, with orbital periods shorter than one day, represent a unique class of exoplanets whose origin remains puzzling. Determining their age distributio…
The Influence of General Relativity on the Spins of Celestial Bodies in Inclined Orbits
Huan-rong Yuan, Ying Wang, Xin Wu +4
Through the Rossiter-McLaughlin effect, several hot Jupiters have been found to exhibit spin-orbit misalignment, and even retrograde orbits. The high obliquity observed in these pl…
Planetary Edge Trends (PET). I. The Inner Edge-Stellar Mass Correlation
Meng-Fei Sun, Ji-Wei Xie, Ji-Lin Zhou +3
The position of the innermost planet (i.e., the inner edge) in a planetary system provides important information about the relationship of the entire system to its host star proper…
FOSSIL: I. The Spin Rate Limit of Jupiter Trojans
Chan-Kao Chang, Ying-Tung Chen, Wesley C. Fraser +25
Rotation periods of 53 small (diameters km) Jupiter Trojans (JTs) were derived using the high-cadence light curves obtained by the FOSSIL phase I survey, a Subaru/Hype…
