New Light-Travel Time Models and Orbital Stability Study of the Proposed Planetary System HU Aquarii
Tobias C. Hinse,Jae Woo Lee,Krzysztof Gozdziewski,Nader Haghighipour,Chung-Uk Lee,Eamon Scullion +5 more
TL;DR: In this paper, the authors proposed a new orbital architecture for the two proposed circumbinary planets around the polar eclipsing binary HU Aquarii, based on the result of a Monte Carlo simulation driving a least-squares Levenberg-Marquardt minimisation algorithm on the observed eclipse egress times.
Proceedings ArticleDOI

TL;DR: The first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH) using any technique was reported by as discussed by the authors , who used the Hubble Space Telescope (HST) to carry out precise astrometry of the source star of the long-duration (t E ≃ 270 days) high-magnification microlensing event MOA-2011-BLG-191/OGLE-11-0462 in the direction of the Galactic bulge.
Journal ArticleDOI
The Eclipsing System V404 Lyr: Light-Travel Times and Gamma Doradus Pulsations
TL;DR: In this article, the physical properties of V404 Lyr exhibiting eclipse timing variations and multi-periodic pulsations from all historical data including the Kepler observations were analyzed and a satisfactory model for the Kepler light curves was obtained through applying a cool spot to the secondary component.
Journal ArticleDOI
1SWASP J093010.78+533859.5: A possible hierarchical quintuple system
Jae-Rim Koo,Jae-Rim Koo,Jae Woo Lee,Byeong-Cheol Lee,Seung-Lee Kim,Chung-Uk Lee,Kyeongsoo Hong,Dong-Joo Lee,Soo-Chang Rey +8 more
TL;DR: In this paper, Li et al. presented the observational results of this kind of rare object, 1SWASP J093010.78+533859.5, for which the doubly eclipsing feature had been detected previously from the SuperWASP photometric archive.
