High-resolution simulations of planetesimal formation in turbulent protoplanetary discs
High-resolution simulations turbulent protoplanetary discs
2011/1/10
We present high-resolution computer simulations of dust dynamics and planetesimal formation in turbulence generated by the magnetorotational instability. We show that the turbulent viscosity associate...
High Resolution HDS/SUBARU chemical abundances of the young stellar cluster Palomar 1

2010/11/9
Context. Palomar 1 is a peculiar globular cluster (GC). It is the youngest Galactic GC and it has been tentatively associated to several of the substructures recently discovered in the Milky Way (MW),...
A High-Resolution Survey of HI Absorption toward the Central 200 pc of the Galactic Center
High-Resolution Survey Galactic Center
2010/11/10
We present an HI absorption survey of the central 250 pc of the Galaxy. Very Large Array (VLA) observations were made at 21 cm in the DnC and CnB con gurations and have a resolution of 15"(0.6 pc at ...
Dissecting the Moth: Discovery of an off-centered ring in the HD 61005 debris disk with high-resolution imaging
circumstellar matter — planetary systems protoplanetary disks — Techniques
2010/11/15
The debris disk known as “The Moth” is named after its unusually asymmetric surface brightness distribution. It is located around the ∼90Myr old G8V star HD 61005 at 34.5 pc and has previously b...
Wavelets with Ridges: A High-Resolution Representation of Cataclysmic Variable Time-Series
methods data analysis — techniques photometric
2010/11/12
Quasi-periodic oscillations and dwarf nova oscillations occur in dwarf novae and nova-like variables during outburst and occasionally during quiescence, and have analogues in high-mass X-ray binaries ...
High-resolution mapping of the physical conditions in two nearby active galaxies based on 12CO(1-0), (2-1) and (3-2) lines
Galaxy Astrophysics (astro-ph.GA)
2010/12/29
We present a detailed analysis of high resolution observations of the three lowest CO transitions in two nearby active galaxies, NGC4569 and NGC4826. The CO(1-0) and (2-1) lines were observed with the...
Calcium and light-elements abundance variations from high resolution spectroscopy in globular clusters

2010/3/8
We use abundances of Ca, O, Na, Al from high resolution UVES spectra of 200 red giants in 17 globular clusters (GCs) to investigate the correlation found by Lee et al. (2009) between chemical enrichme...
