Shadows and spirals in the protoplanetary disk HD 100453
M. Benisty, T. Stolker, A. Pohl +46
Understanding the diversity of planets requires to study the morphology and the physical conditions in the protoplanetary disks in which they form. We observed and spatially resolv…
The Winds from HL Tau
Pamela D. Klaassen, Joseph C. Mottram, Luke T. Maud +1
Outflowing motions, whether a wind launched from the disk, a jet launched from the protostar, or the entrained molecular outflow, appear to be an ubiquitous feature of star formati…
Optical spectroscopy of EX Lupi during quiescence and outburst: Infall, wind, and dynamics in the accretion flow
Aurora Sicilia-Aguilar, Ágnes Kóspál, Johny Setiawan +6
We explore the accretion mechanisms in EX Lupi, prototype of EXor variables, during its quiescence and outburst phases. We analyse high-resolution optical spectra taken before, dur…
Adaptable Radiative Transfer Innovations for Submillimetre Telescopes (ARTIST) - Dust polarisation module (DustPol)
M. Padovani, C. Brinch, J. M. Girart +9
We present a new publicly available tool (DustPol) aimed to model the polarised thermal dust emission. The module DustPol, which is publicly available, is part of the ARTIST (Adapt…
Dust evolution in protoplanetary disks around Herbig Ae/Be stars - The Spitzer view
A. Juhasz, J. Bouwman, Th. Henning +7
In this paper we present mid-infrared spectra of a comprehensive set of Herbig Ae/Be stars observed with the Spitzer Space Telescope. The signal-to-noise ratio of these spectra is…
Spitzer's view on aromatic and aliphatic hydrocarbon emission in Herbig Ae stars
B. Acke, J. Bouwman, A. Juhash +5
The chemistry of astronomical hydrocarbons, responsible for the well-known infrared emission features detected in a wide variety of targets, remains enigmatic. Here we focus on the…
On the interplay between flaring and shadowing in disks around Herbig Ae/Be stars
B. Acke, M. Min, M. van den Ancker +4
Based on the SED, Herbig stars have been categorized into two observational groups, reflecting their overall disk structure: group I members have disks with a higher degree of flar…
EX Lupi in quiescence
N. Sipos, P. Ábrahám, J. Acosta-Pulido +5
EX Lup is the prototype of EXors, a subclass of low-mass pre-main sequence stars whose episodic eruptions are attributed to temporarily increased accretion. In quiescence the optic…
Episodic formation of cometary material in the outburst of a solar-like young star
P. Ábrahám, A. Juhász, C. P. Dullemond +8
Our Solar System originated in interstellar gas and dust; the latter is in the form of amorphous silicate particles and carbonaceous dust. The composition of cometary material show…
MBM 12: young protoplanetary discs at high galactic latitude
G. Meeus, A. Juhasz, Th. Henning +6
(abridged) We present Spitzer infrared observations to constrain disc and dust evolution in young T Tauri stars in MBM 12, a star-forming cloud at high latitude with an age of 2 My…
Evolution of dust and ice features around FU Orionis objects
S. P. Quanz, Th. Henning, J. Bouwman +5
(abridged) We present spectroscopy data for a sample of 14 FUors and 2 TTauri stars observed with the Spitzer Space Telescope or with the Infrared Space Observatory (ISO). Based on…
