Effects of Magnetic Fields on Gas Dynamics and Star Formation in Nuclear Rings
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Nuclear rings at the centers of barred galaxies are known to be strongly magnetized. To explore the effects of magnetic fields on star formation in these rings and nuclear gas flow…
Effects of the Central Mass Concentration on Bar Formation in Disk Galaxies
Dajeong Jang, Woong-Tae Kim
While bars are common in disk galaxies, their formation conditions are not well understood. We use -body simulations to study bar formation and evolution in isolated galaxies co…
Effects of Radiative Diffusion on the Dynamical Corotation Torque in Three-Dimensional Protoplanetary Disks
Han-Gyeol Yun, Woong-Tae Kim, Jaehan Bae +1
The dynamical corotation torque arising from the deformation of the horseshoe orbits, along with the vortensity gradient in the background disk, is important for determining orbita…
Effects of Varying Mass Inflows on Star Formation in Nuclear Rings of Barred Galaxies
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Observations indicate that the star formation rate (SFR) of nuclear rings varies considerably with time and is sometimes asymmetric rather than being uniform across a ring. To unde…
OGLE-2019-BLG-0468Lb,c: two microlensing giant planets around a G-type star
Cheongho Han, Andrzej Udalski, Chung-Uk Lee +37
With the aim of interpreting anomalous lensing events with no suggested models, we conducted a project of reinvestigating microlensing data in and before the 2019 season. In this w…
Star Formation in Nuclear Rings with the TIGRESS Framework
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Nuclear rings are sites of intense star formation at the centers of barred galaxies. To understand what determines the structure and star formation rate (SFR; ) o…
