Very Large Telescope observations of Gomez's Hamburger: Insights into a young protoplanet candidate
(ESO, 2015)
Planets are thought to form in the gas and dust disks around young stars. In particular, it has been proposed that giant planets can form through the gravitational instability of massive extended disks around intermediate-mass ...
Giant planets around two intermediate-mass evolved stars and confirmation of the planetary nature of HIP 67851c
(EDP Sciences, 2015)
Context. Precision radial velocities are required to discover and characterize exoplanets. Optical spectra that exhibit many hundreds of absorption lines can allow the m s(-1) precision levels required for this work. After ...

Four new planets around giant stars and the mass-metallicity correlation of planet-hosting stars
(EDP Sciences, 2016)
Context. Exoplanet searches have revealed interesting correlations between the stellar properties and the occurrence rate of planets. In particular, different independent surveys have demonstrated that giant planets are ...
A gap in the planetesimal disc around HD 107146 and asymmetric warm dust emission revealed by ALMA
(Oxford University Press, 2018)
While detecting low mass exoplanets at tens of au is beyond current instrumentation, debris discs provide a unique opportunity to study the outer regions of planetary
systems. Here we report new ALMA observations of the ...
Shallow transit follow-up from next-generation transit survey: simultaneous observations of HD 106315 with 11 identical telescopes
(Wiley, 2020)
The Next Generation Transit Survey (NGTS) is a photometric survey for transiting exoplanets, consisting of 12 identical 0.2-m telescopes. We report a measurement of the transit of HD 106315 c using a novel observing mode ...
The Magellan/PFS Exoplanet Search: a 55-d period dense Neptune transiting the bright (V = 8.6) star HD 95338
(Oxford University Press, 2020)
We report the detection of a transiting, dense Neptune planet candidate orbiting the bright (V = 8.6) K0.5V star HD 95338. Detection of the 55-d periodic signal comes from the analysis of precision radial velocities from ...
The Ophiuchus DIsc Survey Employing ALMA (ODISEA) – II. The effect of stellar multiplicity on disc properties
(Oxford University Press, 2020)
We present adaptive optics (AO) near-infrared (NIR) observations using VLT/NACO and Keck/NIRC2 of Ophiuchus DIsc Survey Employing ALMA (ODISEA) targets. ODISEA is an ALMA survey of the entire population of circumstellar ...
The next generation transit survey (NGTS)
(Oxford University Press, 2018)
We describe the Next Generation Transit Survey (NGTS), which is a ground-based project searching for transiting exoplanets orbiting bright stars. NGTS builds on the legacy of previous surveys, most notably WASP, and is ...
VIP: Vortex Image Processing package for high-contrast direct imaging
(IOP Publishing Ltd., 2017)
We present the Vortex Image Processing (VIP) library, a python package dedicated to astronomical high-contrast imaging. Our package relies on the extensive python stack of scientific libraries and aims to provide a flexible ...
