Biography

I am currently a fellow of the Nevada Center for Astrophysics (NCfA) at UNLV. I primarily collaborate with Bing Zhang and Zhaohuan Zhu. Prior to my role at UNLV, I pursued my PhD at Stony Brook University under Rosalba Perna. I am a dynamicist interested in a diverse range of topics, including exoplanets, black hole mergers, and tidal disruption events. In addition to my research pursuits, I have a keen interest in astrophysics software development.

SpaceHub

SpaceHub utilizes unique algorithms for fast, precise, and accurate computations for few-body problems, ranging from interacting black holes to planetary dynamics. This few-body gravity integration toolkit can treat black hole dynamics with extreme mass ratios, extreme eccentricities, and very close encounters. SpaceHub offers a variety of integrators with round-off error controls and can handle extremely eccentric orbits and close approaches in long-term integrations.

About me

Drawing

Aside from my scientific endeavors, I have a deep appreciation for the art and architecture of my hometown, Chongqing, known for its ancient Chinese-style buildings nestled in the mountainous terrain of southwest China. This passion, particularly evident in my sketches of iconic locales like ‘HongYa Dong’, stems from a childhood surrounded by the city’s rich cultural background.

Skiing

During my second year of Ph.D. studies, I tried skiing for the first time. Despite a bumpy start that led to a quick meeting with the first-aid patrol, I found myself hooked. It was a surprising but welcomed discovery, offering a hobby that was just challenging and rewarding.

As time went on, skiing became more than just a pastime. It turned into a regular activity where I could see and feel myself getting better, one ski trip at a time. The sense of progress and the fun of speeding down the slopes kept pulling me back.

Even though I started skiing in the US, I became quite interested in the approach of the Canadian Ski Instructors’ Alliance (CSIA) in Canada. Their focus on constant growth and skill development really clicked with me, mirroring my own experiences and enjoyment in the sport.

Now, I’m working slowly towards meeting the Level III certification standard from CSIA, a goal that highlights the commitment and enjoyment I’ve found in skiing over the years.

In the following video, I’ve captured one of my ski seasons with my mates before the pandemic struck. It was a time of camaraderie, laughter, and the simple joy of cruising down the slopes with friends. You can spot me easily – I’m the guy sporting the unmistakably yellow pants.

Jupiter Mass Binary Object (JuMBO) formation from stellar flybys

This work has been motivated by the very recent report of observations by the James Webb Space Telescope (JWST) of candidate Jupiter-Mass Binary Objects (a.k.a JuMBO), whose existence does not readily fits in any current planetary formation theory. More specifically, via dedicated N-body simulations, we set to investigate the possibility that a close flyby can result in the ejection of two planets in outer orbits, which remain bound to one another. The mass ratio between the star and planet in the scattering experiments is set to be 1e-3.
