OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf
Shota Miyazaki, Takahiro Sumi, David P. Bennett +92
We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…
OGLE-2015-BLG-1649Lb: A gas giant planet around a low-mass dwarf
Masayuki Nagakane, Chien-Hsiu Lee, Naoki Koshimoto +66
We report the discovery of an exoplanet in microlensing event OGLE-2015-BLG-1649. The planet/host-star mass ratio is and the projected separation normalized…
Transit timing variations in the WASP-4 planetary system
John Southworth, M. Dominik, U. G. Jorgensen +25
Transits in the planetary system WASP-4 were recently found to occur 80s earlier than expected in observations from the TESS satellite. We present 22 new times of mid-transit that…
An analysis of binary microlensing event OGLE-2015-BLG-0060
Y. Tsapras, A. Cassan, C. Ranc +83
We present the analysis of stellar binary microlensing event OGLE-2015-BLG-0060 based on observations obtained from 13 different telescopes. Intensive coverage of the anomalous par…
Towards high-resolution astronomical imaging
Craig Mackay, David Buscher, Nahid Chowdhury +8
This paper is a report from a recent meeting on "the Future of high-resolution imaging in the visible and infrared", reviewing the astronomical drivers for development and the tech…
Spitzer Microlensing parallax reveals two isolated stars in the Galactic bulge
Weicheng Zang, Yossi Shvartzvald, Tianshu Wang +90
We report the mass and distance measurements of two single-lens events from the 2017 Spitzer microlensing campaign. The ground-based observations yield the detection of finite-sour…
OGLE-2017-BLG-1186: first application of asteroseismology and Gaussian processes to microlensing
Shun-Sheng Li, Weicheng Zang, Andrzej Udalski +102
We present the analysis of the event OGLE-2017-BLG-1186 from the 2017 Spitzer microlensing campaign. This is a remarkable microlensing event because its source is photometrically b…
OGLE-2018-BLG-0022: A Nearby M-dwarf Binary
R. A. Street, E. Bachelet, Y. Tsapras +28
We report observations of the binary microlensing event OGLE-2018-BLG-0022, provided by the ROME/REA Survey, which indicate that the lens is a low-mass binary star consisting of M3…
Physical properties and transmission spectrum of the WASP-74 planetary system from multi-band photometry
L. Mancini, J. Southworth, P. Molliere +32
We present broad-band photometry of eleven planetary transits of the hot Jupiter WASP-74b, using three medium-class telescopes and employing the telescope-defocussing technique. Mo…
Hardware and software for a robotic network of telescopes - SONG
M. F. Andersen, F. Grundahl, J. Christensen-Dalsgaard +7
SONG aims at setting up a network of small 1m telescopes around the globe to observe stars uninterrupted throughout days, weeks and even months. This paper describes the fundamenta…
