OGLE-2016-BLG-1227L: A Wide-separation Planet from a Very Short-timescale Microlensing Event
Cheongho Han, Andrzej Udalski, Andrew Gould +30
We present the analysis of the microlensing event OGLE-2016-BLG-1227. The light curve of this short-duration event appears to be a single-lens event affected by severe finite-sourc…
Origin of Non-axisymmetric Features of Virgo Cluster Early-type Dwarf Galaxies. II. Tidal Effects on Disk Features and Stability
SungWon Kwak, Woong-Tae Kim, Soo-Chang Rey +1
A fraction of dwarf galaxies in the Virgo cluster contain disk features like bars and spiral arms. Using -body simulations, we investigate the effects of tidal forces on the for…
The Nuclear Filaments inside the Circumnuclear Disk in the Central 0.5 pc of the Galactic center
Pei-Ying Hsieh, Patrick M. Koch, Woong-Tae Kim +4
We present CS(7-6) line maps toward the central parsec of the Galactic Center (GC), conducted with the Atacama Large Millimeter/submillimeter Array (ALMA). The primary goal is to f…
Properties of Density and Velocity Gaps Induced by a Planet in a Protoplanetary Disk
Han Gyeol Yun, Woong-Tae Kim, Jaehan Bae +1
Gravitational interactions between a protoplanetary disk and its embedded planet is one of the formation mechanisms of gaps and rings found in recent ALMA observations. To quantify…
Modeling UV Radiation Feedback from Massive Stars: III. Escape of Radiation from Star-forming Giant Molecular Clouds
Jeong-Gyu Kim, Woong-Tae Kim, Eve C. Ostriker
Using a suite of radiation hydrodynamic simulations of star cluster formation in turbulent clouds, we study the escape fraction of ionizing (Lyman continuum) and non-ionizing (FUV)…
Spectroscopic Mass and Host-star Metallicity Measurements for Newly Discovered Microlensing Planet OGLE-2018-BLG-0740Lb
Cheongho Han, Jennifer C. Yee, Andrzej Udalski +63
We report the discovery of the microlensing planet OGLE-2018-BLG-0740Lb. The planet is detected with a very strong signal of , but the interpretation of the signal s…
