Destructuring the disk of AB Aurigae: Dynamics and accretion

Anthony Boccaletti, Emmanuel Di Folco, Anne Dutrey +23

In this paper, we present near-IR polarized images of the AB Aur disk at three epochs spanning 3.85 years with SPHERE/IRDIS, as well as Halpha images obtained with SPHERE/ZIMPOL at…

Chemistry in the GG Tau A Disk: Constraints from H2D+, N2H+, and DCO+ High Angular Resolution ALMA Observations

Parashmoni Kashyap, Liton Majumdar, Anne Dutrey +17

Resolved molecular line observations are essential for gaining insight into the physical and chemical structure of protoplanetary disks, particularly in cold, dense regions where p…

Radial distribution of the carbonaceous nano-grains in the protoplanetary disk around HD 169142

Marie Devinat, Émilie Habart, Éric Pantin +4

HD 169142 is part of the class of (pre-)transitional protoplanetary disks showing multiple carbon nanodust spectroscopic signatures (aromatic, aliphatic) dominating the infrared sp…

Lack of other molecules in CO-rich debris discs: is it primordial or secondary gas?

Grigorii V. Smirnov-Pinchukov, Attila Moór, Dmitry A. Semenov +5

The nature of the gas in CO-rich debris discs remains poorly understood, as it could either be a remnant from the earlier Class II phase or of secondary origin, driven by the destr…

Chemistry in Disks X: The Molecular Content of Proto-planetary Disks in Taurus

S. Guilloteau, L. Reboussin, A. Dutrey +6

(abridged) We used the IRAM 30-m to perform a sensitive wideband survey of 30 protoplanetary disks in the Taurus Auriga region. We simultaneously observed HCO(3-2), HCN(3-2), C…

Faint disks around classical T Tauri stars: small but dense enough to form planets?

V. Piétu, S. Guilloteau, E. di Folco +2

(abridged) Most Class II sources (of nearby star forming regions) are surrounded by disks with weak millimeter continuum emission. These "faint" disks may hold clues to the disk di…

Hot exozodiacal dust resolved around Vega with IOTA/IONIC

D. Defrère, O. Absil, J. -C. Augereau +10

Although debris discs have been detected around a significant number of main-sequence stars, only a few of them are known to harbour hot dust in their inner part where terrestrial…

Evidence against the young hot-Jupiter around BD +20 1790

P. Figueira, M. Marmier, X. Bonfils +11

Context. The young active star BD +20 1790 is believed to host a substellar companion, revealed by radial-velocity measurements that detected the reflex motion induced on the paren…
