Evidence for Hidden Nearby Companions to Hot Jupiters
Dong-Hong Wu, Malena Rice, Songhu Wang
The first discovered extrasolar worlds -- giant, ``hot Jupiter'' planets on short-period orbits -- came as a surprise to solar-system-centric models of planet formation, prompting…
Searching for candidates of coalescing binary black holes formed through chemically homogeneous evolution in GWTC-3
Ying Qin, Yuan-Zhu Wang, Simone S. Bavera +10
The LIGO, Virgo, and KAGRA (LVK) collaboration has announced 90 coalescing binary black holes (BBHs) with to date, however, the origin of their formation cha…
The Aligned Orbit of WASP-148b, the Only Known Hot Jupiter with a Nearby Warm Jupiter Companion, from NEID and HIRES
Xian-Yu Wang, Malena Rice, Songhu Wang +39
We present spectroscopic measurements of the Rossiter-McLaughlin effect for WASP-148b, the only known hot Jupiter with a nearby warm-Jupiter companion, from the WIYN/NEID and Keck/…
On the Angular Momentum Transport Efficiency within the Star Constrained from Gravitational-wave Observations
Ying Qin, Yuan-Zhu Wang, Dong-Hong Wu +2
The LIGO Scientific Collaboration and Virgo Collaboration (LVC) have recently reported in GWTC-2.1 eight additional candidate events with a probability of astrophysical origin grea…
Detecting circumbinary exoplanets and hierarchical stellar triples with the LISA gravitational radiation mission
Jason H. Steffen, Dong-Hong Wu, Shane L. Larson
We investigate the possibility of detecting planetary or stellar companions orbiting white dwarf binaries using the LISA gravitational radiation detector. Specifically, we consider…
Dynamical instability and its implications for planetary system architecture
Dong-Hong Wu, Rachel C. Zhang, Ji-Lin Zhou +1
We examine the effects that dynamical instability has on shaping the orbital properties of exoplanetary systems. Using N-body simulations of non-EMS (Equal Mutual Separation), mult…
TTV-determined Masses for Warm Jupiters and their Close Planetary Companions
Dong-Hong Wu, Songhu Wang, Ji-Lin Zhou +2
Although the formation and the properties of hot Jupiters (with orbital periods d) have attracted a great deal of attention, the origins of warm Jupiters (d) ar…
Transiting Exoplanet Monitoring Project (TEMP). IV. Refined System Parameters, Transit Timing Variations and Orbital Stability of the Transiting Planetary System HAT-P-25
Xian-Yu Wang, Songhu Wang, Tobias C. Hinse +12
We present eight new light curves of the transiting extra-solar planet HAT-P-25b obtained from 2013 to 2016 with three telescopes at two observatories. We use the new light curves,…
Transiting Exoplanet Monitoring Project (TEMP). III. On the Relocation of the Kepler-9~b Transit
Songhu Wang, Dong-Hong Wu, Brett C. Addison +24
The Kepler-9 system harbors three known transiting planets. The system holds significant interest for several reasons. First, the outer two planets exhibit a period ratio that is c…
Transiting Exoplanet Monitoring Project (TEMP). II. Refined System Parameters and Transit Timing Analysis of HAT-P-33b
Y. -H. Wang, S. Wang, H. -G. Liu +19
We present ten -band photometric observations of eight different transits of the hot Jupiter HAT-P-33b, which has been targeted by our Transiting Exoplanet Monitoring Project (T…
Updated Masses for the TRAPPIST-1 Planets
Songhu Wang, Dong-Hong Wu, Thomas Barclay +1
The newly detected TRAPPIST-1 system, with seven low-mass, roughly Earth-sized planets transiting a nearby ultra-cool dwarf, is one of the most important exoplanet discoveries to d…
A possible giant planet orbiting the cataclysmic variable LX Ser
K. Li, S. -M. Hu, J. -L. Zhou +6
LX Ser is a deeply eclipsing cataclysmic variable with an orbital period of . Sixty two new eclipse times were determined by our observations and the AAVSO Internatio…
Detecting planet pairs in mean motion resonances via astrometry method
Dong-Hong Wu, Hui-Gen Liu, Zhou-Yi Yu +2
GAIA leads us to step into a new era with a high astrometry precision of 10 uas. Under such a precision, astrometry will play important roles in detecting and characterizing exopla…
Eclipsing Binaries From the CSTAR Project at Dome A, Antarctica
Ming Yang, Hui Zhang, Songhu Wang +30
The Chinese Small Telescope ARray (CSTAR) has observed an area around the Celestial South Pole at Dome A since 2008. About light curves in the i band were obtained lasting…
