Formation of the Methyl Cation by Photochemistry in a Protoplanetary Disk
Olivier Berné, Marie-Aline Martin-Drumel, Ilane Schroetter +53
Forty years ago it was proposed that gas phase organic chemistry in the interstellar medium was initiated by the methyl cation CH3+, but hitherto it has not been observed outside t…
PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar
Ryan Chown, Ameek Sidhu, Els Peeters +136
(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…
A spectacular jet from the bright 244-440 Orion proplyd: the MUSE NFM view
A. Kirwan, C. F. Manara, E. T. Whelan +8
In this work we present the highest spatial and spectral resolution integral field observations to date of the bipolar jet from the Orion proplyd 244-440 using MUSE NFM) observatio…
PDRs4All: A JWST Early Release Science Program on radiative feedback from massive stars
Olivier Berné, Émilie Habart, Els Peeters +134
Massive stars disrupt their natal molecular cloud material through radiative and mechanical feedback processes. These processes have profound effects on the evolution of interstell…
Herschel survey and modelling of externally-illuminated photoevaporating protoplanetary disks
Jason Champion, Olivier Berné, Silvia Vicente +5
Protoplanetary disks undergo substantial mass-loss by photoevaporation, a mechanism which is crucial to their dynamical evolution. However, the processes regulating the gas energet…
Herschel -PACS observations of [OI] and H2O in Cha II
P. Riviere-Marichalar, A. Bayo, I. Kamp +11
Gas plays a major role in the dynamical evolution of protoplanetary discs. Its coupling with the dust is the key to our understanding planetary formation. Studying the gas content…
[OI] disk emission in the Taurus star forming region
G. Aresu, I. Kamp, R. Meijerink +8
The structure of protoplanetary disks is thought to be linked to the temperature and chemistry of their dust and gas. Whether the disk is flat or flaring depends on the amount of r…
Herschel/PACS Survey of protoplanetary disks in Taurus/Auriga -- Observations of [OI] and [CII], and far infrared continuum
Christian D. Howard, Göran Sandell, William D. Vacca +17
The Herschel Space Observatory was used to observe ~ 120 pre-main-sequence stars in Taurus as part of the GASPS Open Time Key project. PACS was used to measure the continuum as wel…
DIGIT survey of far-infrared lines from protoplanetary discs: II. CO
Gwendolyn Meeus, Colette Salyk, Simon Bruderer +12
CO is an important component of a protoplanetary disc as it is one of the most abundant gas phase species. Furthermore, observations of the CO transitions can be used as a diagnost…
GASPS - a Herschel survey of gas and dust in Protoplanetary Disks: Summary and Initial Statistics
W. R. F. Dent, W. F. Thi, I. Kamp +47
GASPS is a far-infrared line and continuum survey of protoplanetary and young debris disks using PACS on the Herschel Space Observatory. The survey includes [OI] at 63 microns, as…
Ruling out unresolved binaries in five transitional disks VLT/NACO: deep 2.12 and 1.75 μm narrow-band imaging
Silvia Vicente, Bruno Merın, Markus Hartung +8
Aims. We aim at detecting the presence of companions inside the inner hole/gap region of a sample of five well known transitional disks using spatially-resolved imaging in the near…
Size distribution of circumstellar disks in the Trapezium cluster
S. Vicente, J. Alves
In this paper we present results on the size distribution of circumstellar disks in the Trapezium cluster as measured from HST/WFPC2 data. Direct diameter measurements of a sample…
