All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

One of the most mind-boggling topics in philosophical theology is the relationship between divine foreknowledge and human freedom. If God has a complete knowledge of the future due to his epistemic perfection, how can a human being be free with respect to his future action?

Dongchundang Songjoongil (1606-1672) was a scholar who represented Gihoyeahak and Sanlim (山林) influencing the society of Chosŏn dynasty since the middle of 17th century. This report focus on its contemporary purport and reconciliation spirit on the Kyoung (敬) of Dongchundang. The Kyoung is the core idea that elucidates Dongchundang's philosophy and its characteristic. Dongchundang tried to continue to live the life of 'according knowledge and action' (知行一致) and dreamed the world of 'harmonization but not same' (和而不同) which indicates the principle (...) of heaven, meaning the harmony never following suit without reflection and a just and great cause, going through with his original idea through the Kyoung. In addition, Dongchundang expanded the Kyoung from personal existential problems to social ethic practical ones in the viewpoint of more reason than vitality, and aimed to build the ethic kingdom that came the harmony andreconciliation of all the communities together, interacting his subjectivity and the universal. The Kyoung and reconciliation spirit of Dongchundang is the orthodoxy of Dohak(道學), and it made him live moral intention and through real life and summarized the manner and spirit pursuing the just and great cause beyond factions. In this sense, Dongchundang's philosophy is the concentration of the Kyoung and philosophical expression of reconciliation spirit. As the peculiarity of Dongchundang's philosophy is based on the Kyoung, it is the everlasting principle of what one should do and practice in human life. (shrink)
