TRUST I: A 3D externally illuminated slab benchmark for dust radiative transfer

K. D. Gordon, M. Baes, S. Bianchi +8

The radiative transport of photons through arbitrary three-dimensional (3D) structures of dust is a challenging problem due to the anisotropic scattering of dust grains and strong…

Mass estimates for very cold (< 8 K) gas in molecular cloud cores

Juergen Steinacker, Hendrik Linz, Henrik Beuther +2

The mass of prestellar cores is an essential ingredient to understand the onset of star formation in the core. The low level of emission from cold dust may keep parts of it hidden…

Prestellar core modeling in the presence of a filament - The dense heart of L1689B

Juergen Steinacker, Aurore Bacmann, Thomas Henning +1

Short version: We apply a new synergetic radiative transfer method: the derived 1D density profiles are both consistent with a cut through the Herschel PACS/SPIRE and JCMT SCUBA-2…

Benchmarking the Calculation of Stochastic Heating and Emissivity of Dust Grains in the Context of Radiative Transfer Simulations

Peter Camps, Karl Misselt, Simone Bianchi +9

We define an appropriate problem for benchmarking dust emissivity calculations in the context of radiative transfer (RT) simulations, specifically including the emission from stoch…

Coreshine in L1506C - Evidence for a primitive big-grain component or indication for a turbulent core history?

J. Steinacker, C. W. Ormel, M. Andersen +1

The recently discovered coreshine effect can aid in exploring the core properties and in probing the large grain population of the ISM. We discuss the implications of the coreshine…

Detecting scattered light from low-mass molecular cores at 3.6 m - Impact of global effects on the observation of coreshine

J. Steinacker, M. Andersen, W. -F. Thi +1

Recently discovered scattered light at 3-5 m from low-mass cores (so-called "coreshine") reveals the presence of grains around 1 m, which is larger than the grains found in t…

Scattering from dust in molecular clouds: Constraining the dust grain size distribution through near-infrared cloudshine and infrared coreshine

M. Andersen, J. Steinacker, W-F. Thi +3

Context. The largest grains (0.5-1 micron) in the interstellar size distribution are efficient in scattering near- and mid-infrared radiation. These wavelengths are therefore parti…

The Earliest Phases of Star Formation (EPoS): A Herschel Key Program - The precursors to high-mass stars and clusters

Sarah Ragan, Thomas Henning, Oliver Krause +14

(Abridged) We present an overview of the sample of high-mass star and cluster forming regions observed as part of the Earliest Phases of Star Formation (EPoS) Herschel Guaranteed T…

A large, massive, rotating disk around an isolated young stellar object

Sascha P. Quanz, Henrik Beuther, Juergen Steinacker +5

We present multi-wavelengths observations and a radiative transfer model of a newly discovered massive circumstellar disk of gas and dust which is one of the largest disks known to…

The Protostar in the massive Infrared Dark Cloud IRDC18223-3

H. Beuther, J. Steinacker

At the onset of high-mass star formation, accreting protostars are deeply embedded in massive cores made of gas and dust. Their spectral energy distribution is still dominated by t…

3D Continuum radiative transfer in complex dust configurations around young stellar objects and active nuclei II. 3D Structure of the dense molecular cloud core Rho Oph D

J. Steinacker, A. Bacmann, Th. Henning +2

Constraints on the density and thermal 3D structure of the dense molecular cloud core Rho Oph D are derived from a detailed 3D radiative transfer modeling. Two ISOCAM images at 7 a…

The Degree of CO Depletion in Pre-stellar Cores

Aurore Bacmann, Bertrand Lefloch, Cecilia Ceccarelli +3

We present new results on CO depletion in a sample of nearby pre-stellar cores, based on observations of the millimeter C17O and C18O lines and the 1.3 mm dust emission with the IR…
