A wide-orbit giant planet in the high-mass b Centauri binary system

Markus Janson, Raffaele Gratton, Laetitia Rodet +24

Planet formation occurs around a wide range of stellar masses and stellar system architectures. An improved understanding of the formation process can be achieved by studying it ac…

Binary Formation in the Orion Nebula Cluster: Exploring the Sub-stellar Limit

Matthew De Furio, Michael R. Meyer, Megan Reiter +3

We present results constraining the multiplicity of the very low mass stars and sub-stellar objects in the Orion Nebula Cluster (ONC). Our sample covers primary masses 0.012-0.1M$_…

Characterizing the protolunar disk of the accreting companion GQ Lupi B

Tomas Stolker, Sebastiaan Y. Haffert, Aurora Y. Kesseli +11

GQ Lup B is a young and accreting, substellar companion that appears to drive a spiral arm in the circumstellar disk of its host star. We report high-contrast imaging observations…

On The Orbital Separation Distribution and Binary Fraction of M Dwarfs

Nicholas Susemiehl, Michael R. Meyer

We present a new estimate for the binary fraction (the fraction of stars with a single companion) for M dwarfs using a log-normal fit to the orbital separation distribution. We use…

High contrast imaging at 10 microns, a search for exoplanets around: Eps Indi A, Eps Eri, Tau Ceti, Sirius A and Sirius B

P. Pathak, D. J. M. Petit dit de la Roche, M. Kasper +15

The direct imaging of rocky exoplanets is one of the major science goals for upcoming large telescopes. The contrast requirement for imaging such planets is challenging. However, t…

High-precision astrometric studies in direct imaging with SPHERE

A. -L. Maire, G. Chauvin, A. Vigan +15

Orbital monitoring of exoplanetary and stellar systems is fundamental for analysing their architecture, dynamical stability and evolution, and mechanisms of formation. Current high…
