Summary of the Third International Planetary Dunes Workshop: Remote Sensing and Image Analysis of Planetary Dunes, Flagstaff, Arizona, USA, June 12-15, 2012 [PDF]

open access: yes, 2013
The Third International Planetary Dunes Workshop took place in Flagstaff, AZ, USA during June 12-15, 2012. This meeting brought together a diverse group of researchers to discuss recent advances in terrestrial and planetary research on aeolian bedforms.

Exploiting the performance gains of modern disk drives by enhancing data locality. [PDF]

open access: yes, 2009
Due to the widening performance gap between RAM and disk drives, a large number of I/O optimization methods have been proposed and designed to alleviate the impact of this gap.

Disk evolution, element abundances and cloud properties of young gas giant planets [PDF]

open access: yes, 2014
ChHc and PBR highlights financial support of the European Community under the FP7 program by an ERC starting grant. PW, IK, and WFT acknowledge funding from the European Union Seventh Framework Programme FP7-2011 under grant agreement No.

Microlensing search for extra solar planets [PDF]

open access: yes, 2015
Gravitational microlensing may be used to probe distant stars for planetary companions. The presence of a planet in the vicinity of a star acting as the lens may cause a short lived anomaly in the observed lightcurve of the lensing event.

On the interaction between embedded planets and the corotation region of protoplanetary discs [PDF]

open access: yes, 2015
PhDDisc material in the corotation region librates with respect to low-mass planets on horseshoe trajectories. The exchange of angular momentum associated with this libration gives rise to the non-linear corotation torque (the horseshoe drag).

Long extra-tropical planetary wave propagation in the presence of slowly varying mean flow and bottom topography. II: ray propagation and comparison with observations [PDF]

open access: yes, 2003
Ray theory is used to predict phase and group velocities for long planetary waves under realistic, albeit slowly varying, oceanic conditions. The results are compared with local theory using fields smoothed to the same amount (9° latitude/longitude) as ...

Characterizing circumstellar disk around young stars [PDF]

open access: yes, 2010
The circumstellar disks play a fundamental role in star and planet formation process. Studies on circumstellar disks are generally carried on following two viable approaches: "statistical" studies, where a large samples of sources are measured to ...

On the multiple generations of planetary embryos [PDF]

open access: yes, 2022
Global models of planet formation tend to begin with an initial set of planetary embryos for the sake simplicity. While this approach gives valuable insights on the evolution of the initial embryos, the initial distribution itself is a bold assumption ...

Dynamical interactions and planetary growth in a protoplanetary disk

open access: yes, 2012
International audienceEarth- to Neptune-mass planets launch spiral density waves in gaseous protoplanetary disks and undergo type 1 migration. In isothermal disks, type 1 migration is inward and the migration timescale is inversely proportional to the ...

Discovery of a planetary-mass companion within the gap of the transition disk around PDS 70 [PDF]

open access: yes, 2018
International audienceContext.Young circumstellar disks are the birthplaces of planets. Their study is of prime interest to understand the physical and chem-ical conditions under which planet formation takes place.
