| Time：115/10/14 (Wed.) 14:20~16:20 Speaker：Prof.吳亞霖(Ya-Lin Wu) 國立臺灣師範大學物理學系/Department of Physics, National Taiwan Normal University Title：Planetary-Mass Companions: Case Studies Abstract： Direct imaging surveys have uncovered an intriguing population of planetary-mass companions. These objects are massive gas giants residing on extremely wide orbits, with separations of hundreds and even thousands of astronomical units. Their wide separations provide a unique opportunity for detailed characterization of their physical properties and surrounding environments. In this talk, I will briefly introduce the techniques used to discover these objects, discuss the physical processes underlying their multiwavelength spectral energy distributions, and review their potential formation scenarios. I will also present recent work from our group on the accretion disks surrounding these objects. Place：S101, Gongguan Campus, NTNU |
