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…

Accreting protoplanets: Spectral signatures and magnitude of gas and dust extinction at H alpha

G. -D. Marleau, Y. Aoyama, R. Kuiper +14

Accreting planets have been seen at Ha (H alpha), but targeted searches have not been fruitful. For planets, accretion tracers should come from the shock itself, exposing them to e…

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…

Comparison of planetary Hα-emission models: A new correlation with accretion luminosity

Yuhiko Aoyama, Gabriel-Dominique Marleau, Masahiro Ikoma +1

Accreting planets have been detected through their hydrogen-line emission, specifically H. To interpret this, stellar-regime empirical correlations between the H luminosity $…

Molecular mapping of the PDS70 system: No molecular absorption signatures from the forming planet PDS70 b

G. Cugno, P. Patapis, T. Stolker +7

Aims. We aim to detect molecules in the atmosphere of the young forming companion PDS70 b by searching for atmospheric absorption features typical of substellar objects. Methods. W…

The First Dynamical Mass Measurement in the HR 8799 System

G. Mirek Brandt, Timothy D. Brandt, Trent J. Dupuy +2

HR 8799 hosts four directly imaged giant planets, but none has a mass measured from first principles. We present the first dynamical mass measurement in this planetary system, find…

Perturbers: SPHERE detection limits to planetary-mass companions in protoplanetary disks

R. Asensio-Torres, Th. Henning, F. Cantalloube +25

The detection of a wide range of substructures such as rings, cavities and spirals has become a common outcome of high spatial resolution imaging of protoplanetary disks, both in t…

A faint companion around CrA-9: protoplanet or obscured binary?

V. Christiaens, M. -G. Ubeira-Gabellini, H. Cánovas +16

Understanding how giant planets form requires observational input from directly imaged protoplanets. We used VLT/NACO and VLT/SPHERE to search for companions in the transition disc…

BEAST begins: Sample characteristics and survey performance of the B-star Exoplanet Abundance Study

Markus Janson, Vito Squicciarini, Philippe Delorme +20

While the occurrence rate of wide giant planets appears to increase with stellar mass at least up through the A-type regime, B-type stars have not been systematically studied in la…
