Making hot Jupiters in stellar clusters II: efficient formation in binary systems

Daohai Li, Alexander J. Mustill, Melvyn B. Davies +1

Observations suggested that the occurrence rate of hot Jupiters (HJs) in open clusters is largely consistent with the field () but in the binary-rich cluster M67, the rate…

Binary asteroid dissociation and accretion around white dwarfs

Zeping Jin, Daohai Li, Zong-Hong Zhu

About 25-50% of white dwarfs (WDs) show metal lines in their spectra. Among the widely accepted explanations for this effect is that the these WDs are accreting asteroids that are…

Making hot Jupiters in stellar clusters: the importance of binary exchange

Daohai Li, Alexander J. Mustill, Melvyn B. Davies +1

It has been suggested that the occurrence rate of hot Jupiters (HJs) in open clusters might reach several per cent, significantly higher than that of the field ( a per cent).…

Metal pollution of the solar white dwarf by solar system small bodies

Daohai Li, Alexander J. Mustill, Melvyn B. Davies

White dwarfs (WDs) often show metal lines in their spectra, indicating accretion of asteroidal material. Our Sun is to become a WD in several Gyr. Here, we examine how the solar WD…

Accretion of tidally disrupted asteroids onto white dwarfs: direct accretion versus disk processing

Daohai Li, Alexander J. Mustill, Melvyn B. Davies

Atmospheric heavy elements have been observed in more than a quarter of white dwarfs (WDs) at different cooling ages, indicating ongoing accretion of asteroidal material, whilst on…

Encounters involving planetary systems in birth environments: the significant role of binaries

Daohai Li, Alexander J. Mustill, Melvyn B. Davies

Most stars form in a clustered environment. Both single and binary stars will sometimes encounter planetary systems in such crowded environments. Encounter rates for binaries may b…

Capture of satellites during planetary encounters A case study of the Neptunian moons Triton and Nereid

Daohai Li, Anders Johansen, Alexander J. Mustill +2

Single-binary scattering may lead to an exchange where the single object captures a component of the binary, forming a new binary. This has been well studied in encounters between…

The origin of Neptune's unusual satellites from a planetary encounter

Daohai Li, Apostolos A. Christou

The Neptunian satellite system is unusual, comprising Triton, a large ( km) moon on a close-in, circular, yet retrograde orbit, flanked by Nereid, the largest irregular s…

Fly-by encounters between two planetary systems II: Exploring the interactions of diverse planetary system architectures

Daohai Li, Alexander J. Mustill, Melvyn B. Davies

Planetary systems formed in clusters may be subject to stellar encounter flybys. Here we create a diverse range of representative planetary systems with different orbital scales an…

Fly-by encounters between two planetary systems I: solar system analogues

Daohai Li, Alexander J. Mustill, Melvyn B. Davies

Stars formed in clusters can encounter other stars at close distances. In typical open clusters in the Solar neighbourhood containing hundreds or thousands of member stars, ten to…

Secular resonances between bodies on close orbits II: prograde and retrograde orbits for irregular satellites

Daohai Li, Apostolos A. Christou

In extending the analysis of the four secular resonances between close orbits in Li and Christou (Celest Mech Dyn Astron 125:133-160, 2016) (Paper I), we generalise the semianalyti…

Secular resonances between bodies on close orbits: a case study of the Himalia prograde group of jovian irregular satellites

Daohai Li, Apostolos A. Christou

The gravitational interaction between two objects on similar orbits can effect noticeable changes in the orbital evolution even if the ratio of their masses to that of the central…
