OGLE-2015-BLG-1649Lb: A Gas Giant Planet around a Low-mass Dwarf (2019)
Journal Article

We report the discovery of an exoplanet from the analysis of the gravitational microlensing event OGLE-2015-BLG-1649 that challenges the core accretion model of planet formation and appears to support the disk instability model. The planet/host-star... Read More about OGLE-2015-BLG-1649Lb: A Gas Giant Planet around a Low-mass Dwarf.

Transit timing variations in the WASP-4 planetary system (2019)
Journal Article

Transits in the planetary system WASP-4 were recently found to occur 80 s earlier than expected in observations from the TESS satellite. We present 22 new times of mid-transit that confirm the existence of transit timing variations, and are well fitt... Read More about Transit timing variations in the WASP-4 planetary system.

OGLE-2017-BLG-1186: first application of asteroseismology and Gaussian processes to microlensing (2019)
Journal Article

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 bright and variable, which makes it possible to perform an asteroseismi...

The EBLM Project VI. The mass and radius of five low-mass stars in F+M binaries discovered by the WASP survey (2019)
Journal Article

Some M-dwarfs around F-/G-type stars have been measured to be hotter and larger than predicted by stellar evolution models. Inconsistencies between observations and models need addressing with more mass, radius and luminosity measurements of low-mass... Read More about The EBLM Project VI. The mass and radius of five low-mass stars in F+M binaries discovered by the WASP survey.

An analysis of binary microlensing event OGLE-2015-BLG-0060 (2019)
Journal Article

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 parts of the light curve was achieved by automated follow-up observations... Read More about An analysis of binary microlensing event OGLE-2015-BLG-0060.

SpUpNIC (Spectrograph Upgrade: Newly Improved Cassegrain): a versatile and efficient low- to medium-resolution, long-slit spectrograph on the South African Astronomical Observatory's 1.9-m telescope (2019)
Journal Article

We report on the extensively upgraded Cassegrain spectrograph on the South African Astronomical Observatory (SAAO) 1.9-m telescope. The introduction of new collimator and camera optics, a new detector and controller, a rear-of-slit viewing camera to...

Qatar Exoplanet Survey: Qatar-8b, 9b, and 10b—A Hot Saturn and Two Hot Jupiters (2019)
Journal Article

In this paper we present three new extrasolar planets from the Qatar Exoplanet Survey. Qatar-8b is a hot Saturn, with M P = 0.37 M J and R P = 1.3 R J, orbiting a solar-like star every P orb = 3.7 days. Qatar-9b is a hot Jupiter with a mass of M P =...

OGLE-2018-BLG-0022: A Nearby M-dwarf Binary (2019)
Journal Article

We report observations of the binary microlensing event OGLE-2018-BLG-0022, provided by the Robotic Observations of Microlensing Events (ROME)/Reactive Event Assessment (REA) Survey, which indicate that the lens is a low-mass binary star consisting o...

Spectroscopic confirmation of the binary nature of the hybrid pulsator KIC 5709664 found with the frequency modulation method (2019)
Journal Article

We started a program to search for companions around hybrid δ Sct/γ Dor stars with the frequency modulation method using Kepler data. Our best candidate was KIC 5709664, where we could identify Fourier peaks with sidelobes, suggesting binary orbital...

Physical properties and transmission spectrum of the WASP-74 planetary system from multiband photometry (2019)
Journal Article

We present broad-band photometry of 11 planetary transits of the hot Jupiter WASP-74 b, using three medium-class telescopes and employing the telescope-defocusing technique. Most of the transits were monitored through I filters and one was simultaneo...

Spitzer Microlensing Parallax for OGLE-2017-BLG-0896 Reveals a Counter-rotating Low-mass Brown Dwarf (2019)
Journal Article

The kinematics of isolated brown dwarfs in the Galaxy, beyond the solar neighborhood, is virtually unknown. Microlensing has the potential to probe this hidden population, as it can measure both the mass and five of the six phase-space coordinates (a...

OGLE-2014-BLG-1186: gravitational microlensing providing evidence for a planet orbiting the foreground star or for a close binary source? (2019)
Journal Article

Discussing the particularly long gravitational microlensing event OGLE-2014-BLG-1186 with a time-scale tE ~ 300 d, we present a methodology for identifying the nature of localised deviations from single-lens point-source light curves, which ensures t...

The PDS 110 observing campaign – photometric and spectroscopic observations reveal eclipses are aperiodic (2019)
Journal Article

PDS 110 is a young disc-hosting star in the Orion OB1A association. Two dimming events of similar depth and duration were seen in 2008 (WASP) and 2011 (KELT), consistent with an object in a closed periodic orbit. In this paper, we present data from a...
