The Early Light Curve of a Type Ia Supernova 2021hpr in NGC 3147: Progenitor Constraints with the Companion Interaction Model
Gu Lim, Myungshin Im, Gregory S. H. Paek +19
The progenitor system of Type Ia supernovae (SNe Ia) is expected to be a close binary system of a carbon/oxygen white dwarf (WD) and a non-degenerate star or another WD. Here, we p…
Discovery of a young low-mass brown dwarf transiting a fast-rotating F-type star by the Galactic Plane eXoplanet (GPX) survey
P. Benni, A. Y. Burdanov, V. V. Krushinsky +64
We announce the discovery of GPX-1 b, a transiting brown dwarf with a mass of and a radius of , the first sub-stell…
High-resolution spectroscopic monitoring observations of FU Orionis-type object, V960 Mon
Sunkyung Park, Jeong-Eun Lee, Tae-Soo Pyo +9
We present the results of high-resolution (R 30,000) optical and near-infrared spectroscopic monitoring observations of a FU Orionis-type object, V960 Mon, which underwent an…
IGRINS Spectral Library
Sunkyung Park, Jeong-Eun Lee, Wonseok Kang +12
We present a library of high-resolution (R / 45,000) and high signal-to-noise ratio (S/N 200) near-infrared spectra for stars of a wide range of spe…
High Resolution Optical and NIR Spectra of HBC 722
Jeong-Eun Lee, Sunkyung Park, Joel D. Green +4
We present the results of high resolution (R30,000) optical and near-IR spectroscopic monitoring observations of HBC 722, a recent FU Orionis object that underwent an accretio…
Wilson-Bappu Effect: Extended to Surface Gravity
Sunkyung Park, Wonseok Kang, Jeong-Eun Lee +1
Wilson and Bappu found a tight correlation between the stellar absolute visual magnitude (Mv) and the width of the Ca II K emission line for late-type stars in 1957. Here, we revis…
Tool for Automatic Measurement of Equivalent width (TAME)
Wonseok Kang, Sang-Gak Lee
We present a tool for measuring the equivalent width (EW) in high-resolution spectra. The Tool for Automatic Measurement of Equivalent width (TAME)provides the EWs of spectral line…
Medium Resolution Spectral Library of Late-Type Stellar Templates in Near-Infrared Band
Huynh Anh N. Le, Wonseok Kang, Soojong Pak +5
We present medium resolution (R = 5000-6000) spectra in the near-infrared band, 1.4-1.8 microns, for template stars in G, K, and M types observed by the echelle spectrometer, IRCS,…
Abundances of Refractory Elements for G-type Stars with Extrasolar Planets
Wonseok Kang, Sang-Gak Lee, Kang-Min Kim
We confirm the difference of chemical abundance between stars with and without exoplanet, as well as present the relation between chemical abundances and the physical properties of…
High Resolution Optical Spectra of HBC 722 after Outburst
Jeong-Eun Lee, Wonseok Kang, Sang-Gak Lee +5
We report the results of our high resolution optical spectroscopic monitoring campaign ( = 3800 -- 8800 A, R = 30000 -- 45000) of the new FU Orionis-type object HBC 722. We obse…
