ExoplaNeT accRetion mOnitoring sPectroscopic surveY (ENTROPY) III. Optical He I line profiles of the accreting super Jupiter Delorme 1 (AB)b
Gayathri Viswanath, Mickaël Bonnefoy, Catherine Dougados +8
High-resolution spectroscopic observations of helium emission lines provide a powerful probe of accretion geometry in classical T Tauri stars, revealing regions not well traced by…
ExoplaNeT accRetion mOnitoring sPectroscopic surveY (ENTROPY) - II. Time series of Balmer line profiles of Delorme 1(AB)b
Dorian Demars, Mickaël Bonnefoy, Catherine Dougados +14
Accretion processes in the planetary-mass regime remain poorly constrained, yet they strongly influence planet formation, evolution, and the composition of circumplanetary disks (C…
Giant planets population around B stars from the first part of the BEAST survey
P. Delorme, A. Chomez, V. Squicciarini +23
Exoplanets form from circumstellar protoplanetary discs whose fundamental properties (notably their extent, composition, mass, temperature and lifetime) depend on the host star pro…
Exoplanet accretion monitoring spectroscopic survey (ENTROPY) I. Evidence for magnetospheric accretion in the young isolated planetary-mass object 2MASS J11151597+1937266
Gayathri Viswanath, Simon C. Ringqvist, Dorian Demars +7
Accretion among planets is a poorly understood phenomenon, due to lack of both observational and theoretical studies. Detection of emission lines from accreting gas giants facilita…
An imaged 15Mjup companion within a hierarchical quadruple system
A. Chomez, V. Squicciarini, A. -M. Lagrange +20
Since 2019, the direct imaging B-star Exoplanet Abundance Study (BEAST) at SPHERE@VLT has been scanning the surroundings of young B-type stars in order to ascertain the ultimate fr…
BEAST detection of a brown dwarf and a low-mass stellar companion around the young bright B star HIP 81208
Gayathri Viswanath, Markus Janson, Raffaele Gratton +15
Recent observations from B-star Exoplanet Abundance Study (BEAST) have illustrated the existence of sub-stellar companions around very massive stars. In this paper, we present the…
Forbidden emission lines in protostellar outflows and jets with MUSE
Lizxandra Flores-Rivera, Mario Flock, Nicolás Kurtovic +14
Forbidden emission lines in protoplanetary disks are a key diagnostic in studies of the evolution of the disk and the host star. We report spatially resolved emission lines, [OI] 6…
Resolved near-UV hydrogen emission lines at 40-Myr super-Jovian protoplanet Delorme 1 (AB)b: Indications of magnetospheric accretion
Simon C. Ringqvist, Gayathri Viswanath, Yuhiko Aoyama +3
We have followed up on our observations of the ~ 40-Myr, and still accreting, PMC Delorme 1 (AB)b. We used high-resolution spectroscopy to characterise the accretion process furthe…
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…
