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…
A Formation-Stage Bottleneck for Exomoons around Close-in Rocky Planets
Rongxi Bi, Hongping Deng, Christian Reinhardt +2
Massive moons around rocky exoplanets are expected outcomes of giant impacts, yet no exomoon has been securely confirmed. We address this problem using meshless finite-mass simulat…
Where Do Hot Jupiters Come From? Revisiting Tidal Disruption and Ejection in High-Eccentricity Migration
Qianli Fan, Shang-Fei Liu
The origin of hot Jupiters remains a key open question. In the high-eccentricity migration scenario, traditional coreless models predict a strict tidal exclusion zone within $\sim…
Sub-Neptunes Show a Stronger Correlation with Cold Jupiters than Super-Earths Especially in Metal-rich Systems
Di-Chang Chen, Fei Dai, Bo Ma +2
Correlations between the inner small planets and cold giants encodes the formation and evolution of planetary systems. It remains unclear if the correlation differs on the two side…
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.…
Capture and Stability of Resonant Planet Pairs in Turbulent Disk
Linghong Lin, Beibei Liu, Fei Dai +6
We present a theoretical framework for the resonance capture and stability of two-planet systems in turbulent disks. By incorporating stochastic forcing (parameterized by ) alon…
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…
Exoplanet Ephemerides Change Observations (ExoEcho). II. Transit timing variation analysis of Brown Dwarfs around Solar-type Stars
Wenqin Wang, Xinyue Ma, Zhangliang Chen +3
Transit timing variation (TTV) is a useful tool for studying the orbital properties of transiting objects. However, few TTV studies have been done on transiting brown dwarfs (BDs)…
exoALMA XI: ALMA Observations and Hydrodynamic Models of LkCa 15: Implications for Planetary Mass Companions in the Dust Continuum Cavity
Charles H. Gardner, Andrea Isella, Hui Li +43
In the past decade, the Atacama Large Millimeter/submillimeter Array (ALMA) has revealed a plethora of substructures in the disks surrounding young stars. These substructures have…
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…
Constraining the Presence of Companion Planets in Hot Jupiter Planetary System Using TTV Observation from TESS
Zixin Zhang, Wenqin Wang, Xinyue Ma +7
The presence of another planetary companion in a transiting exoplanet system can impact its transit light curve, leading to sinusoidal transit timing variations (TTV). By utilizing…
Surviving in the Hot Neptune Desert: The Discovery of the Ultra-Hot Neptune TOI-3261b
Emma Nabbie, Chelsea X. Huang, Jennifer A. Burt +45
The recent discoveries of Neptune-sized ultra-short period planets (USPs) challenge existing planet formation theories. It is unclear whether these residents of the Hot Neptune Des…
The Impact-driven Atmospheric Loss of Super-Earths around Different Spectral Type Host Stars
Wei Zhong, Cong Yu, Shi Jia +1
The planet's mass loss is important for the planet's formation and evolution. The radius valley (RV) is believed to be triggered by evaporation-induced mass loss. As an alternative…
Evolution of the Planetary Obliquity: The Eccentric Kozai-Lidov Mechanism Coupled with Tide
Xiumin Huang, Jianghui Ji, Shangfei Liu +2
The planetary obliquity plays a significant role in determining physical properties of planetary surfaces and climate. As direct detection is constrained due to the present observa…
