Jupiter’s Metastable Companions
The Astrophysical Journal LettersJovian co-orbitals share Jupiter’s orbit and exhibit 1:1 mean-motion resonance with the planet. This includes >10,000 so-called Trojan asteroids surrounding the leading (L4) and trailing (L5) Lagrange points, viewed as stable groups dating back to planet

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Tree-ring Structure of Galactic Bar Resonance in N-body Simulations
The Astrophysical JournalWe study the structure and evolution of the Galactic bar’s resonant phase space in self-consistent N -body simulations of the Milky Way, with and without perturbations from the Sagittarius dwarf galaxy. In an idealized disk evolution model in which stars

An optimum time-stepping scheme for N-body simulations [PDF]
, 2017 We present a new time-stepping criterion for N-body simulations that is based on the true dynamical time of a particle. This allows us to follow the orbits of particles correctly in all environments since it has better adaptivity than previous time ...

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion
Advanced Engineering Materials, EarlyView.Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

N-body simulations of star forming regions [PDF]
, 2019 This thesis contains a body of work using N-body simulations and numerical methods to study star forming regions. It begins by introducing relevant topics, such as the basic picture of star formation, the en- vironment(s) that stars form in, stellar ...

Dynamical and Secular Stability of Mutually Inclined Planetary Systems
The Astrophysical JournalMultiple analytical, semi-analytical, and empirical stability criteria have been derived in the literature for two-planet systems. But, the dependence of the stability limit on the initial mutual inclination between the inner and outer orbits is not well
