A kinematic excess in the annular gap and gas depleted cavity in the disc around HD 169142
Himanshi Garg, Christophe Pinte, Iain Hammond +6
We present ALMA band 6 images of the 12CO, 13CO and C18O J=2-1 line emissions for the circumstellar disc around HD 169142, at ~8 au spatial resolution. We resolve a central gas dep…
The bright side of the light curve: a general photometric model of non-transiting exorings
Jorge I. Zuluaga, Mario Sucerquia, Jaime A. Alvarado-Montes
Rings around exoplanets (exorings) are one of the most expected discoveries in exoplanetary research. There is an increasing number of theoretical and observational efforts for det…
Orbital and dynamical analysis of the system around HR 8799. New astrometric epochs from VLT/SPHERE and LBT/LUCI
A. Zurlo, K. Gozdziewski, C. Lazzoni D. Mesa +44
HR\,8799 is a young planetary system composed of 4 planets and a double debris belt. Being the first multi-planetary system discovered with the direct imaging technique, it has bee…
Vertically extended and asymmetric CN emission in the Elias 2-27 protoplanetary disk
T. Paneque-Carreño, A. Miotello, E. F. van Dishoeck +5
Elias 2-27 is a young star that hosts an extended, bright and inclined disk of dust and gas. The inclination and extreme flaring of the disk make Elias 2-27 an ideal target to stud…
Molecules with ALMA at Planet-forming Scales (MAPS). A Circumplanetary Disk Candidate in Molecular Line Emission in the AS 209 Disk
Jaehan Bae, Richard Teague, Sean M. Andrews +29
We report the discovery of a circumplanetary disk (CPD) candidate embedded in the circumstellar disk of the T Tauri star AS 209 at a radial distance of about 200 au (on-sky separat…
Constraints on TESS albedos for five hot Jupiters
Martin Blažek, Petr Kabáth, Anjali A. A. Piette +10
Photometric observations of occultations of transiting exoplanets can place important constraints on the thermal emission and albedos of their atmospheres. We analyse photometric m…
