Grain alignment and rotational disruption by radiative torques in exoplanet atmospheres
Thiem Hoang, A. Lazarian
Dust clouds are ubiquitous in the atmospheres of hot Jupiters and affect their observable properties. The alignment of dust grains in the clouds and resulting dust polarization is…
Detectability of Thermal Emission from Sub-Relativistic Objects
Thiem Hoang, Abraham Loeb
We calculate the surface temperature and the resulting brightness of sub-relativistic objects moving through the Solar system due to collisional heating by gas and radiative heatin…
Can Planet Nine Be Detected Gravitationally by a Sub-Relativistic Spacecraft?
Thiem Hoang, Abraham Loeb
Planet 9 was proposed as an explanation for the clustering of orbits for some trans-Neuptunian objects. Recently, the use of a sub-relativistic spacecraft was proposed to indirectl…
Evolution of Dust and Water Ice in Cometary Comae by Radiative Torques
Thiem Hoang, Ngo-Duy Tung
Comets provide unique information about the physical and chemical properties of the environment in which the Solar system was formed. Understanding how cometary dust and ice evolve…
Rotational Disruption of Dust and Ice by Radiative Torques in Protoplanetary Disks and Implications for Observations
Ngo-Duy Tung, Thiem Hoang
Dust and ice mantles on dust grains play an important role in various processes in protoplanetary disks (PPDs) around a young star, including planetesimal formation, surface chemis…
