Astronomy & Astrophysics, 592, Article A120. https://doi.org/10.1051/0004-6361/201628864

Context. We show the benefits of using electron-multiplying CCDs and the shift-and-add technique as a tool to minimise the effects of atmospheric turbulence, such as blending between stars in crowded fields, and to avoid saturated stars in the fields...

Contamination from a nearby star cannot explain the anomalous transmission spectrum of the ultra-short period giant planet WASP-103b (2016)
Journal Article

The planet in the WASP-103 system is an excellent candidate for transmission spectroscopy because of its large radius and high temperature. Application of this technique found a variation of radius with wavelength which was far too strong to be expla...

Another one grinds the dust: variability of the planetary debris disc at the white dwarf SDSS J104341.53+085558.2 (2016)
Journal Article

Monthly Notices of the Royal Astronomical Society, 462(2), 1461 - 1469. https://doi.org/10.1093/mnras/stw1760

We report 9 yr of optical spectroscopy of the metal-polluted white dwarf SDSS J104341.53+085558.2, which presents morphological variations of the line profiles of the 8600 Å Ca?II triplet emission from the gaseous component of its debris disc. Simila... Read More about Another one grinds the dust: variability of the planetary debris disc at the white dwarf SDSS J104341.53+085558.2.

Mass Measurements Of Isolated Objects From Space-Based Microlensing (2016)

We report on the mass and distance measurements of two single-lens events from the 2015 Spitzer microlensing campaign. With both finite-source effect and microlens parallax measurements, we find that the lens of OGLE-2015-BLG-1268 is very likely a br...

The WASP-98 planetary system represents a rare case of a hot Jupiter hosted by a metal-poor main-sequence star. We present a follow-up study of this system based on multiband photometry and high-resolution spectroscopy. Two new transit events of WASP...

We confirm the planetary nature of Kepler-539?b (aka Kepler object of interest K00372.01), a giant transiting exoplanet orbiting a solar-analogue G2?V star. The mass of Kepler-539?b was accurately derived thanks to a series of precise radial velocity...
