Thermal Infrared and Optical Photometry of Asteroidal Comet C/2002 CE
Tomohiko Sekiguchi, Seidai Miyasaka, Budi Dermawan +4
C/2002 CE is an object in a retrograde elliptical orbit with Tisserand parameter indicating a likely origin in the Oort Cloud. It appears to be a rather inactive co…
The AKARI IRC asteroid flux catalogue: updated diameters and albedos
V. Alí-Lagoa, T. G. Müller, F. Usui +1
The AKARI IRC All-sky survey provided more than twenty thousand thermal infrared observations of over five thousand asteroids. Diameters and albedos were obtained by fitting an emp…
Efficiency of radial transport of ices in protoplanetary disks probed with infrared observations: the case of CO
Arthur D. Bosman, Alexander G. G. M. Tielens, Ewine F. van Dishoeck
The efficiency of radial transport of icy solid material from outer disk to the inner disk is currently unconstrained. Efficient radial transport of icy dust grains could significa…
ALMA continuum observations of the protoplanetary disk AS 209. Evidence of multiple gaps opened by a single planet
D. Fedele, M. Tazzari, R. Booth +8
The paper presents new high angular resolution ALMA 1.3 mm dust continuum observations of the protoplanetary system AS 209 in the Ophiuchus star forming region. The dust continuum…
PRIMASS visits Hilda and Cybele groups
M. N. De Prá, N. Pinilla-Alonso, J. M. Carvano +5
The Cybele and Hilda dynamical groups delimit the outer edge of the asteroid belt. Their compositional distribution is a key element to constrain evolutionary models of the Solar S…
Photometric survey, modelling, and scaling of long-period and low-amplitude asteroids
A. Marciniak, P. Bartczak, T. Müller +40
The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes. As a consequence of these select…
Feedback-limited Accretion: Variable Luminosity from Growing Planets
Matías Gárate, Jorge Cuadra, Matias Montesinos +1
Planets form in discs of gas and dust around stars, and continue to grow by accretion of disc material while available. Massive planets clear a gap in their protoplanetary disc, bu…
Small Bodies Near and Far (SBNAF): a benchmark study on physical and thermal properties of small bodies in the Solar System
T. G. Müller, A. Marciniak, C. Kiss +15
The combination of visible and thermal data from the ground and astrophysics space missions is key to improving the scientific understanding of near-Earth, main-belt, trojans, cent…
The circumstellar disk HD169142: gas, dust and planets acting in concert?
A. Pohl, M. Benisty, P. Pinilla +33
HD169142 is an excellent target to investigate signs of planet-disk interaction due to the previous evidence of gap structures. We performed J-band (~1.2μm) polarized intensity…
Gas mass tracers in protoplanetary disks: CO is still the best
Tamara Molyarova, Vitaly Akimkin, Dmitry Semenov +3
Protoplanetary disk mass is a key parameter controlling the process of planetary system formation. CO molecular emission is often used as a tracer of gas mass in the disk. In this…
Inferring giant planets from ALMA millimeter continuum and line observations in (transition) disks
Stefano Facchini, Paola Pinilla, Ewine F. van Dishoeck +1
Potential signatures of proto-planets embedded in their natal protoplanetary disk are radial gaps or cavities in the continuum emission in the IR-mm wavelength range. ALMA observat…
CO emission tracing a warp or radial flow within 100 au in the HD 100546 protoplanetary disk
Catherine Walsh, Cail Daley, Stefano Facchini +1
We present spatially resolved ALMA images of CO J=3-2 emission from the protoplanetary disk around HD100546. We model the spatially-resolved kinematic structure of the CO emission.…
Molecular abundances and C/O ratios in chemically evolving planet-forming disk midplanes
Christian Eistrup, Catherine Walsh, Ewine F van Dishoeck
(Abridged) Exoplanet atmospheres are thought be built up from accretion of gas as well as pebbles and planetesimals in the midplanes of planet-forming disks. The chemical compositi…
The thermal emission of Centaurs and Trans-Neptunian objects at millimeter wavelengths from ALMA observations
E. Lellouch, R. Moreno, T. Müller +9
The sensitivity of ALMA makes it possible to detect thermal mm/submm emission from small/distant Solar System bodies at the sub-mJy level. Measured fluxes are primarily sensitive t…
CN rings in full protoplanetary disks around young stars as probes of disk structure
P. Cazzoletti, E. F. van Dishoeck, R. Visser +2
Bright ring-like structure emission of the CN molecule has been observed in protoplanetary disks. We investigate whether such structures are due to the morphology of the disk itsel…
Seeds of Life in Space (SOLIS) III. Formamide in protostellar shocks: evidence for gas-phase formation
C. Codella, C. Ceccarelli, P. Caselli +47
Context: Modern versions of the Miller-Urey experiment claim that formamide (NHCHO) could be the starting point for the formation of metabolic and genetic macromolecules. Intri…
VLA observations of the disk around the young brown dwarf 2MASS J044427+2512
L. Ricci, H. Rome, P. Pinilla +3
We present multi-wavelength radio observations obtained with the VLA of the protoplanetary disk surrounding the young brown dwarf 2MASS J04442713+2512164 (2M0444) in the Taurus sta…
Spin states of asteroids in the Eos collisional family
J. Hanuš, M. Delbo', V. Alí-Lagoa +33
Eos family was created during a catastrophic impact about 1.3 Gyr ago. Rotation states of individual family members contain information about the history of the whole population. W…
Physical properties of dusty protoplanetary disks in Lupus: evidence for viscous evolution?
M. Tazzari, L. Testi, A. Natta +9
The formation of planets strongly depends on the total amount as well as on the spatial distribution of solids in protoplanetary disks. Thanks to the improvements in resolution and…
ALMA Observations of the Young Substellar Binary System 2M1207
L. Ricci, P. Cazzoletti, I. Czekala +10
We present ALMA observations of the 2M1207 system, a young binary made of a brown dwarf with a planetary-mass companion at a projected separation of about 40 au. We detect emission…
Asteroid shapes and thermal properties from combined optical and mid-infrared photometry inversion
Josef Durech, Marco Delbo, Benoit Carry +2
Optical lightcurves can be used for the shape and spin reconstruction of asteroids. Due to unknown albedo, these models are scale-free. When thermal infrared data are available, th…
