A Search for Exoplanets around Northern Circumpolar Stars X. The origin of radial velocity variations in the evolved star HD 216595
Sang-Hee Kim, Byeong-Cheol Lee, Shenghong Gu +9
Detecting planetary companions around evolved stars, particularly asymptotic giant branch (AGB) stars, is challenging due to intrinsic stellar variability such as surface convectio…
Long-period radial velocity variations of nine M red giants: The detection of sub-stellar companions around HD 6860 and HD 112300
Byeong-Cheol Lee, Hee-Jin Do, Myeong-Gu Park +7
Context. Certain periodic variations of radial velocities (RV) of wobbling giants originate from exoplanets. Indeed, a number of exoplanets have been discovered around giant stars.…
Gamma-Ray Bursts with Extended Emission: Classifications, Energy Correlations and Radiation Properties
X. L. Zhang, C. T. Zhang, X. J. Li +4
Thanks to more and more gamma-ray bursts with measured redshift and extended emission detected by the recent space telescopes, it is urgent and possible to check whether those prev…
Classifying Gamma-Ray Bursts with Gaussian Mixture Model
En-Bo Yang, Zhi-Bin Zhang, Chul-Sung Choi +1
Using Gaussian Mixture Model (GMM) and Expectation Maximization Algorithm, we perform an analysis of time duration () for \textit{CGRO}/BATSE, \textit{Swift}/BAT and \texti…
Radio Afterglows and Host Galaxies of Gamma-Ray Bursts
Long-Biao Li, Zhi-Bin Zhang, Yong-Feng Huang +5
Considering the contribution of the emission from the host galaxies of gamma-ray bursts (GRBs) to the radio afterglows, we investigate the effect of host galaxies on observations s…
Microlensing by a wide-separation planet: detectability and boundness
Yoon-Hyun Ryu, Myeong-Gu Park, Heon-Young Chang +1
We explore the detection condition of a wide-separation planet through the perturbation induced by the planetary caustic for various microlensing parameters, especially for the siz…
