ExoEcho: Exoplanet Ephemerides Change Observations. III. A JWST Survey for Transit Timing Variations of 37 Exoplanets
Yunke Wu, Zixin Zhang, Xinyue Ma +6
Transit timing variations (TTVs) provide a powerful probe of planetary dynamics and orbital evolution. We extend the ExoEcho project by incorporating James Webb Space Telescope (JW…
Constraining the presence of exotrojans in hot Jupiter systems using TTV observations from TESS
Zixin Zhang, Wenqin Wang, Xinyue Ma +8
Co-orbital bodies (Trojans) share a 1:1 mean-motion resonance with a planet. Although Trojans are common in the Solar System, none has yet been confirmed in an exoplanetary system.…
Searching for White Dwarf Candidates Formed Through Binary evolution in Star Clusters
Huahui Yan, Li Wang, David R. Miller +11
White dwarfs (WDs), the evolutionary endpoints of most stars, can form through both single-star and binary channels. While single-star evolutionary models enable reliable WD age es…
Evidence for a Nonzero Eccentricity Superpuff Exoplanet WASP-107 b Using JWST Occultation Observation
Yunke Wu, Zixin Zhang, Xinyue Ma +6
WASP-107~b is an extremely low-density super-puff exoplanet whose inflated radius and evidence of strong internal heating make it a key target for understanding planetary structure…
Fates of the sub-stellar objects (FOSSO) I. Fates of the known brown dwarfs in main-sequence--BD binaries
Zhangliang Chen, Hongming Jin, Hongwei Ge +4
Context. Understanding the survival and orbital evolution of brown dwarf (BD) companions during the post-main-sequence (MS) evolution of their host stars is increasingly important,…
Short-Period Small Planets with High Mutual Inclinations are more Common around Metal-Rich Stars
Xinyan Hua, Sharon Xuesong Wang, Dongsheng An +7
We present a correlation between the stellar metallicities and the mutual inclinations of multi-planet systems hosting short-period small planets (a/Rs<12, Rp<4Re). We analyzed 89…
Exoplanet Ephemerides Change Observations (ExoEcho). I. Transit Timing Analysis of Thirty-Seven Exoplanets using HST/WFC3 Data
Xinyue Ma, Wenqin Wang, Zixin Zhang +6
The ExoEcho project is designed to study the photodynamics of exoplanets by leveraging high-precision transit timing data from ground- and space-based telescopes. Some exoplanets a…
