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…
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…
