Microlensing Optical Depth Revisited with Recent Star Counts
Yoon-Hyun Ryu, Heon-Young Chang, Myeong-Gu Park +1
More reliable constraints on the microlensing optical depth comes from a better understanding of the Galactic model. Based on well-constrained Galactic bulge and disk models constr…
Precise Radial Velocities of Polaris: Detection of Amplitude Growth
Byeong-Cheol Lee, David. E. Mkrtichian, Inwoo Han +2
We present a first results from a long-term program of a radial velocity study of Cepheid Polaris (F7 Ib) aimed to find amplitude and period of pulsations and nature of secondary p…
Seoul National University Bright Quasar Survey in Optical (SNUQSO) I: First Phase Observations and Results
Induk Lee, Myungshin Im, Minjin Kim +7
We present results from the first phase of the Seoul National University Bright Quasar Survey in Optical (SNUQSO) as well as its basic observational setup. Previous and current lar…
Microlensing under Shear
Yoon-Hyun Ryu, Myeong-Gu Park
We investigate the distortions due to this shear in the microlensing light curves and in the astrometric microlensing centroid shift trajectories. As expected, the light curve devi…
Equations of General Relativistic Radiation Hydrodynamics from Tensor Formalism
Myeong-Gu Park
Radiation interacts with matter via exchange of energy and momentum. When matter is moving with a relativistic velocity or when the background spacetime is strongly curved, rigorou…
Korean Nova Records in A.D. 1073 and A.D. 1074: R Aquarii
Hong-Jin Yang, Myeong-Gu Park, Se-Hyung Cho +1
R Aqr is known to be a symbiotic binary system with an associated extended emission nebula, possibly produced by a historic outburst. To find the associated historic records, we se…
