A Likely Close-in Low-mass Stellar Companion to the Transitional Disk Star HD 142527
With the uniquely high contrast within 0.''1 ({Delta}mag(L') = 5-6.5 mag) available using Sparse Aperture Masking with NACO at Very Large Telescope, we detected asymmetry in the flux from the HerbigExpand

A survey of young, nearby, and dusty stars conducted to understand the formation of wide-orbit giant planets - VLT/NaCo adaptive optics thermal and angular differential imaging
Context. Over the past decade, direct imaging has confirmed the existence of substellar companions on wide orbits from their parent stars. To understand the formation and evolution mechanisms ofExpand

Global Climate and Atmospheric Composition of the Ultra-hot Jupiter WASP-103b from HST and Spitzer Phase Curve Observations
We present thermal phase curve measurements for the hot Jupiter WASP-103b observed with Hubble/WFC3 and Spitzer/IRAC. The phase curves have large amplitudes and negligible hotspot offsets, indicativeExpand

An M-dwarf star in the transition disk of Herbig HD 142527: physical parameters and orbital elements.
S.L. acknowledges fruitful discussions with S. Casassus about the existence of HD 142527B and the inner disk of HD 142527A. This research made use of Astropy, a community-developed core PythonExpand

A global cloud map of the nearest known brown dwarf
Brown dwarfs—substellar bodies more massive than planets but not massive enough to initiate the sustained hydrogen fusion that powers self-luminous stars—are born hot and slowly cool as they age. AsExpand

Discovery of a planetary-mass companion within the gap of the transition disk around PDS 70
Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime interest to understand the physical and chemical conditions under which planet formation takes place. OnlyExpand

Discovery of a warm, dusty giant planet around HIP 65426
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 unprecedentedExpand

Direct-imaging discovery of a 12–14 Jupiter-mass object orbiting a young binary system of very low-mass stars
Context. Though only a handful of extrasolar planets have been discovered via direct imaging, each of these discoveries had tremendous impact on our understanding of planetary formation, stellarExpand

The architecture of the LkCa 15 transitional disk revealed by high-contrast imaging⋆
We present four new epochs of Ks-band images of the young pre-transitional disk around LkCa 15 and perform extensive forward modeling to derive the physical parameters of the disk. We findExpand
