The 3D Architecture of a pair of 6:1 Resonant Brown Dwarfs around the Naked-eye star Ophiuchi

Tianshenhong Sang, Guang-Yao Xiao, Ying-Yi Cao +8

We present a revisiting study of the brown dwarf pair orbiting the naked-eye () K-giant ~Ophiuchi, located only 44\,pc from our Solar system. By jointly analysing archiva…

Misaligned circumbinary discs around unequal-mass eccentric binaries: alignment, morphology, and binary accretion variability

Ruiqi Yang, Jeremy L. Smallwood, Hongping Deng +4

Binary systems are ubiquitous in the Universe and often host circumbinary discs that are misaligned with the binary orbital plane. Such misalignments can affect disc evolution and…

Nii-body: Bayesian Inference of Multiplanet Dynamics via N-body Simulations

Hong-Fei Jia, Sheng Jin, Dong-Hong Wu +1

Many exoplanetary systems are multiplanet configurations whose long-term dynamics are governed by N-body gravitational interactions. Consequently, their detection signatures cannot…

Breaking the Mass Inclination Degeneracy of Radial Velocity Measurements via Monitoring von Zeipel-Lidov-Kozai Cycles: Implications in the HD 41004 System

Zhizhen Qin, Shang-Fei Liu, Bo Ma +1

We investigate the dynamical stability of the S-type planet in the compact binary HD 41004. Using -body simulations, we find that the planet could be dynamically stable at a mut…

Fate of the remnant in tidal stripping event: repeating and non-repeating

Jin-Hong Chen, Lixin Dai, Shang-Fei Liu +1

Tidal disruption events (TDE) occur when a star ventures too close to a massive black hole. In a partial TDE (pTDE), the star only grazes the tidal radius, causing the outer envelo…

Observational characteristics of circum-planetary-mass-object disks in the era of James Webb Space Telescope

Xilei Sun, Pinghui Huang, Ruobing Dong +1

Recent observations have confirmed circumplanetary disks (CPDs) embedded in parental protoplanetary disks (PPDs). On the other hand, planetary-mass companions (PMCs) and planetary-…

White dwarf magnetospheres: Shielding volatile content of icy objects and implications for volatile pollution scarcity

Wen-Han Zhou, Shang-Fei Liu, Douglas N. C. Lin

Context. About 25% -- 50% of white dwarfs are found to be contaminated by heavy elements, which are believed to originate from external sources such as planetary materials. Element…

Observability of substructures in planet-forming disk in (sub)cm wavelength with SKA and ngVLA

Yinhao Wu, Shang-Fei Liu, Haochang Jiang +1

Current imaging observations of protoplanetary disks using ALMA primarily focus on the sub-millimeter wavelength, leaving a gap in effective observational approaches for centimeter…

Planetesimal Growth in Evolving Protoplanetary Disks: Constraints from the Pebble Supply

Tong Fang, Hui Zhang, Shangfei Liu +2

In the core accretion model, planetesimals grow by mutual collisions and engulfing millimeter-to-centimeter particles, i.e., pebbles. Pebble accretion can significantly increase th…

Tidal Stripping of a White Dwarf by an Intermediate-Mass Black Hole

Jin-Hong Chen, Rong-Feng Shen, Shang-Fei Liu

During the inspiralling of a white dwarf (WD) into an intermediate-mass black hole (~ 10^{2-5} M_sun), both gravitational waves (GWs) and electromagnetic (EM) radiation are emitted…

Observable tests for the light-sail scenario of interstellar objects

Wen-Han Zhou, Shang-Fei Liu, Yun Zhang +1

We scrutinize the light sail scenario of the first interstellar object (ISO) 1I/2017 U1 (`Oumuamua) by making comparisons between physical models and observational constraints. The…

The Measurement of Dynamic Tidal Contribution to Apsidal Motion in Heartbeat Star KIC 4544587

Jian-wen Ou, Cong Yu, Ming Yang +5

Apsidal motion is a gradual shift in the position of periastron. The impact of dynamic tides on apsidal motion has long been debated, because the contribution could not be quantifi…

Orbital migration and circularization of tidal debris by Alfvén-wave drag: circumstellar debris and pollution around white dwarfs

Yun Zhang, Shang-Fei Liu, Douglas N. C. Lin

A significant fraction of white dwarfs (WDs) exhibit signs of ongoing accretion of refractory elements at rates -- kg s, among which, 37 WDs were detected to…

The Formation of Jupiter's Diluted Core by a Giant Impact

Shang-Fei Liu, Yasunori Hori, Simon Müller +4

The Juno mission has provided an accurate determination of Jupiter's gravitational field, which has been used to obtain information about the planet's composition and internal stru…

Science with a ngVLA: Imaging planetary systems in the act of forming with the ngVLA

Luca Ricci, Andrea Isella, Shang-Fei Liu +1

The discovery of thousands of exoplanets has shown that the birth of planets is a very efficient process in nature. Several physical mechanisms have been proposed to describe the a…
