Probing the innermost region of the AU microscopii debris disc
(EDP Sciences, 2022)
Context. AU Mic is a young and nearby M-dwarf star harbouring a circumstellar debris disc and one recently discovered planet on an eight-day orbit. Large-scale structures within the disc were also discovered and are moving ...
K2-140b – an eccentric 6.57 d transiting hot Jupiter in Virgo
(Oxford University Press, 2018)
We present the discovery of K2-140b, a P = 6.57 d Jupiter-mass (M-P = 1.019 +/- 0.070 M-Jup) planet transiting a V = 12.5 (G5-spectral type) star in an eccentric orbit (e = 0.120(-0.046)(+0.056)) detected using a combination ...
Discovery of a warm, dusty giant planet around HIP 65426
(EDP Sciences, 2017)
Aims. The SHINE program is a high-contrast near-infrared survey of 600 young, nearby stars aimed at searching for and characterizing new planetary systems using VLT/SPHERE's unprecedented high-contrast and high-angular-resolution ...
Searching for Hα emitting sources around MWC 758 SPHERE/ZIMPOL high-contrast imaging
(EDP. sciences S.A, 2018-05-23)
Context. MWC 758 is a young star surrounded by a transitional disk. The disk shows an inner cavity and spiral arms that could be caused by the presence of protoplanets. Recently, a protoplanet candidate has been detected ...
The Pan-Pacific Planet Search. IV. Two super-Jupiters in a 3:5 resonance orbiting the giant star HD 33844
(IOP PUBLISHING, 2016)
We report the discovery of two giant planets orbiting the K giant HD 33844 based on radial velocity data from three independent campaigns. The planets move on nearly circular orbits with semimajor axes a(b) = 1.60 +/- 0.02 ...
New constraints on the disk characteristics and companion candidates around T Chamaeleontis with VLT/SPHERE
(EDP Sciences, 2017)
Context. The transition disk around the T Tauri star T Cha possesses a large gap, making it a prime target for high-resolution imaging in the context of planet formation. Aims. We aim to find signs of disk evolutionary ...
The ALMA early science view of FUor/EXor objects - V. Continuum disc masses and sizes
(Oxford University Press, 2018)
Low-mass stars build a significant fraction of their total mass during short outbursts of enhanced accretion known as FUor and EXor outbursts. FUor objects are characterized by a sudden brightening of similar to 5 mag at ...
Upper limits for mass and radius of objects around proxima cen from SPHERE/VLT
(Oxford University Press, 2017)
The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Centauri using Spectro-Polarimetric High-contrast ...
A HARPS RV search for planets around young nearby stars
(EDP Sciences, 2020)
Context. Young nearby stars are good candidates in the search for planets with both radial velocity (RV) and direct imaging techniques. This, in turn, allows for the computation of the giant planet occurrence rates at all ...
Unveiling the beta pictoris system, coupling high contrast imaging, interferometric, and radial velocity data
(EDP Science, 2020)
Context. The nearby and young beta Pictoris system hosts a well resolved disk, a directly imaged massive giant planet orbiting at similar or equal to 9 au, as well as an inner planet orbiting at similar or equal to 2.7 au, ...
