The scarcity of white dwarf-brown dwarf binaries in the solar neighbourhood: A population synthesis study
Alejandro Santos-García, Santiago Torres, Alberto Rebassa-Mansergas +3
White dwarf--brown dwarf (WD--BD) binaries are intrinsically rare systems that provide a unique opportunity to study binary evolution and the formation of substellar companions. De…
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…
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.…
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,…
A magnetic white dwarf formed through a binary merger within 35 million years
Huahui Yan, Jiamao Lin, Rizhong Zheng +15
White dwarfs (WDs) represent the final evolutionary stage of most stars, typically originating from progenitor stars with masses below approximately 8 to 10 …
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)…
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…
Probing the shape of the brown dwarf desert around main-sequence A-F-G-type stars using post-common-envelope WDBD binaries
Zhangliang Chen, Yizhi Chen, Chen Chen +2
Brown dwarfs (BDs) possessing masses within the range are rare around solar-type main-sequence (MS) stars, which gives rise to the brown dwarf desert (BDD). One…
Long-term Orbital Period Variation of Hot Jupiters from Transiting Time Analysis using TESS Survey Data
Wenqin Wang, Zixin Zhang, Zhangliang Chen +3
Many hot Jupiters may experience orbital decays, which are manifested as long-term transit timing variations. We have analyzed 7068 transits from the Transiting Exoplanet Survey Sa…
