TOI-1994b: A Low Mass Eccentric Brown Dwarf Transiting A Subgiant Star
Emma Page, Joshua Pepper, Duncan Wright +22
We present the discovery of TOI-1994b, a low-mass brown dwarf transiting a hot subgiant star on a moderately eccentric orbit. TOI-1994 has an effective temperature of $7700^{+720}_…
Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit
Nolan Grieves, François Bouchy, Monika Lendl +52
We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exopla…
OGLE-2017-BLG-0039: Microlensing Event with Light from the Lens Identified from Mass Measurement
C. Han, Y. K. Jung, A. Udalski +58
We present the analysis of the caustic-crossing binary microlensing event OGLE-2017-BLG-0039. Thanks to the very long duration of the event, with an event time scale $t_{\rm E}\sim…
A study of light travel time effect in short-period MOA eclipsing binaries via eclipse timing
M. C. A. Li, N. J. Rattenbury, I. A. Bond +23
A sample of 542 eclipsing binaries (EBs) with periods shorter than 2 d were selected from the Microlensing Observations in Astrophysics (MOA) EB catalogue (Li et al. 2017) for ecli…
Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020
Tianshu Wang, Wei Zhu, Shude Mao +83
We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…
The First Eclipsing Binary Catalogue from the MOA-II database
M. C. A. Li, N. J. Rattenbury, A. Bond +25
We present the first catalogue of eclipsing binaries in two MOA fields towards the Galactic bulge, in which over 8,000 candidates, mostly contact and semi-detached binaries of peri…
