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…
Protoplanetary disk insights from the first ERIS/APP survey at 4 μm
F. Maio, V. Roccatagliata, D. Fedele +17
We present high-contrast imaging observations of seven protoplanetary disks at 4um using the ERIS on the VLT. This study focuses on detecting scattered light from micron-sized dust…
Implications of the discovery of AF Lep b: The mass-luminosity relation for planets in the Pic Moving Group and the L-T transition for young companions and free-floating planets
R. Gratton, M. Bonavita, D. Mesa +7
Dynamical masses of young planets aged between 10 and 200 Myr detected in imaging play a crucial role in shaping models of giant planet formation. Regrettably, only a few such obje…
Stellar companions and Jupiter-like planets in young associations
R. Gratton, M. Bonavita, D. Mesa +9
Recently, combining high-contrast imaging and space astrometry we found that Jupiter-like (JL) planets are frequent in the beta Pic moving group (BPMG) around those stars where the…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): HD 34700 A unveils an inner ring
G. Columba, E. Rigliaco, R. Gratton +18
Context. The study of protoplanetary disks is fundamental to understand their evolution and interaction with the surrounding environment, and to constrain planet formation mechanis…
Jupiter-like planets might be common in a low-density environment
Raffaele Gratton, Dino Mesa, Mariangela Bonavita +6
Radial velocity surveys suggest that the Solar System may be unusual and that Jupiter-like planets have a frequency <20% around solar-type stars. However, they may be much more com…
AF Lep b: the lowest mass planet detected coupling astrometric and direct imaging data
D. Mesa, R. Gratton, P. Kervella +6
Aims. Using the direct imaging technique we searched for low mass companions around the star AF Lep that presents a significant proper motion anomaly (PMa) signal obtained from the…
Signs of late infall and possible planet formation around DR Tau using VLT/SPHERE and LBTI/LMIRCam
D. Mesa, C. Ginski, R. Gratton +31
Context. Protoplanetary disks around young stars often contain substructures like rings, gaps, and spirals that could be caused by interactions between the disk and forming planets…
The SPHERE infrared survey for exoplanets (SHINE)- I Sample definition and target characterization
S. Desidera, G. Chauvin, M. Bonavita +105
Large surveys with new-generation high-contrast imaging instruments are needed to derive the frequency and properties of exoplanet populations with separations from 5 to 300…
Limits on the presence of planets in systems with debris disks: HD 92945 and HD 107146
D. Mesa, S. Marino, M. Bonavita +38
Recent observations of resolved cold debris disks at tens of au have revealed that gaps could be a common feature in these Kuiper belt analogues. Such gaps could be evidence for th…
SPHERE+: Imaging young Jupiters down to the snowline
A. Boccaletti, G. Chauvin, D. Mouillet +130
SPHERE (Beuzit et al,. 2019) has now been in operation at the VLT for more than 5 years, demonstrating a high level of performance. SPHERE has produced outstanding results using a…
The Ring Structure in the MWC 480 Disk Revealed by ALMA
Yao Liu, Giovanni Dipierro, Enrico Ragusa +20
Gap-like structures in protoplanetary disks are likely related to planet formation processes. In this paper, we present and analyze high resolution (0.17*0.11 arcsec) 1.3 mm ALMA c…
High-Contrast study of the candidate planets and protoplanetary disk around HD~100546
E. Sissa, R. Gratton, A. Garufi +62
The nearby Herbig Be star HD100546 is known to be a laboratory for the study of protoplanets and their relation with the circumstellar disk that is carved by at least 2 gaps. We ob…
New disk discovered with VLT/SPHERE around the M star GSC 07396-00759
E. Sissa, J. Olofsson, A. Vigan +30
Debris disks are usually detected through the infrared excess over the photospheric level of their host star. The most favorable stars for disk detection are those with spectral ty…
Evolution of protoplanetary disks from their taxonomy in scattered light: Group I vs. Group II
Antonio Garufi, Gwendolyn Meeus, Myriam Benisty +13
High-resolution imaging reveals a large morphological variety of protoplanetary disks. To date, no constraints on their global evolution have been found from this census. An evolut…
Narrow Na and K Absorption Lines Toward T Tauri Stars - Tracing the Atomic Envelope of Molecular Clouds
I. Pascucci, S. Edwards, M. Heyer +5
We present a detailed analysis of narrow of NaI and KI absorption resonance lines toward nearly 40 T Tauri stars in Taurus with the goal of clarifying their origin. The NaI 5889.95…
