The international pulsar timing array project: using pulsars as a gravitational wave detector
G. Hobbs, A. Archibald, Z. Arzoumanian +55
The International Pulsar Timing Array project combines observations of pulsars from both Northern and Southern hemisphere observatories with the main aim of detecting ultra-low fre…
The interface between the stellar wind and interstellar medium around R Cassiopeiae revealed by far-infrared imaging
T. Ueta, R. E. Stencel, I. Yamamura +11
The circumstellar dust shells of intermediate initial-mass (about 1 to 8 solar masses) evolved stars are generated by copious mass loss during the asymptotic giant branch phase. Th…
Radiation thermo-chemical models of protoplanetary disks II. Line diagnostics
I. Kamp, I. Tilling, P. Woitke +2
Methods. We use the recently developed disk code ProDiMo to calculate the physico-chemical structure of protoplanetary disks and apply the Monte-Carlo line radiative transfer code…
Photochemistry of the PAH pyrene in water ice: the case for ion-mediated solid-state astrochemistry
J. Bouwman, H. M. Cuppen, A. Bakker +2
Context. Icy dust grains play an important role in the formation of complex inter- and circumstellar molecules. Observational studies show that polycyclic aromatic hydrocarbons (PA…
On the velocity dispersion of young star clusters: super-virial or binaries?
M. Gieles, H. Sana, S. F. Portegies Zwart
Many young extra-galactic clusters have a measured velocity dispersion that is too high for the mass derived from their age and total luminosity, which has led to the suggestion th…
The magnetic field of the evolved star W43A
N. Amiri, W. H. T. Vlemmings, H. J. van Langevelde
The majority of the observed planetary nebulae exhibit elliptical or bipolar structures. Theoretical modeling has indicated that magnetically collimated jets may be responsible for…
Dense and warm molecular gas in the envelopes and outflows of southern low-mass protostars
T. A. van Kempen, E. F. van Dishoeck, M. R. Hogerheijde +1
Observations of dense molecular gas lie at the basis of our understanding of the density and temperature structure of protostellar envelopes and molecular outflows. We aim to chara…
Radiation-Hydrodynamic Models of X-Ray & EUV Photoevaporating Protoplanetary Discs
J. E. Owen, B. Ercolano, C. J. Clarke +1
(Abridged) We present the first radiation-hydrodynamic model of a protoplanetary disc irradiated with an X-EUV spectrum. In a model where the total ionizing luminosity is divided e…
PROSAC: A Submillimeter Array survey of low-mass protostars. II. The mass evolution of envelopes, disks, and stars from the Class 0 through I stages
Jes K. Jorgensen, Ewine F. van Dishoeck, Ruud Visser +5
The key question about early protostellar evolution is how matter is accreted from the large-scale molecular cloud, through the circumstellar disk onto the central star. A sample o…
Misaligned spin and orbital axes cause the anomalous precession of DI Herculis
Simon Albrecht, Sabine Reffert, Ignas A. G. Snellen +1
The orbits of binary stars precess as a result of general relativistic effects, forces arising from the asphericity of the stars, and forces from additional stars or planets in the…
C2D Spitzer-IRS spectra of disks around T Tauri stars. IV. Crystalline silicates
J. Olofsson, J. -C. Augereau, E. F. van Dishoeck +13
Dust grains in the planet forming regions around young stars are expected to be heavily processed due to coagulation, fragmentation and crystallization. This paper focuses on the c…
Methanol masers probing the ordered magnetic field of W75N
G. Surcis, W. H. T. Vlemmings, R. Dodson +1
The role of magnetic fields during the protostellar phase of high-mass star-formation is a debated topic. In particular, it is still unclear how magnetic fields influence the forma…
APEX-CHAMP+ high-J CO observations of low-mass young stellar objects: II. Distribution and origin of warm molecular gas
T. A. van Kempen, E. F. van Dishoeck, R. Guesten +6
The origin and heating mechanisms of warm (50<T<200 K) molecular gas in low-mass young stellar objects (YSOs) are strongly debated. Both passive heating of the inner collapsing env…
A kinetic Monte Carlo study of desorption of H2 from graphite (0001)
E. Gavardi, H. M. Cuppen, L. Hornekaer
The formation of H2 in the interstellar medium proceeds on the surfaces of silicate or carbonaceous particles. To get a deeper insight of its formation on the latter substrate, thi…
On the Relationship Between Debris Disks and Planets
Ágnes Kóspál, David R. Ardila, Attila Moór +1
Dust in debris disks is generated by collisions among planetesimals. The existence of these planetesimals is a consequence of the planet formation process, but the relationship bet…
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…
On the metallicity gradient of the Galactic disk
S. Pedicelli, G. Bono, B. Lemasle +15
Aims: The iron abundance gradient in the Galactic stellar disk provides fundamental constraints on the chemical evolution of this important Galaxy component. However the spread aro…
Dust coagulation and fragmentation in molecular clouds. I. How collisions between dust aggregates alter the dust size distribution
C. W. Ormel, D. Paszun, C. Dominik +1
In dense molecular clouds collisions between dust grains alter the ISM-dust size distribution. We study this process by inserting the results from detailed numerical simulations of…
