N-Body Simulations of Planetesimal Evolution:Effect of Varying Impactor Mass Ratio
planetesimals asteroids planetary formation collisional physics
2015/12/25
We present results from direct N-body simulations of collisions between gravitational aggregates of varying size as part of a study to parameterize planetesimal growth in the Solar System. We find tha...
The unusual vertical mass distribution of NGC 4013 seen through the Spitzer Survey of Stellar Structure in Galaxies (S4G)
Spitzer Survey Stellar Structure Galaxies (S4G)
2011/9/27
NGC 4013 is a nearby Sb edge-on galaxy known for its "prodigious" HI warp and its "giant" tidal stream. Previous work on this unusual object shows that it cannot be fitted satisfactorily by a canonica...
Self-bound models of compact stars and recent mass-radius measurements
Self-bound models compact stars recent mass-radius measurements
2011/10/20
The exact composition of a specific class of compact stars, historically referred to as "neutron stars", is still quite unknown. Possibilities ranging from hadronic to quark degrees of freedom, includ...
LoCuSS: The Sunyaev-Zel'dovich Effect and Weak Lensing Mass Scaling Relation
dovich Effect Weak Lensing Mass Scaling Relation
2011/10/21
We present the first weak-lensing-based scaling relation between galaxy cluster mass, M_wl, and integrated Compton parameter Y_sph. Observations of 18 galaxy clusters at z~0.2 were obtained with the S...
Mass Loss, Destruction and Detection of Sun-grazing and -impacting Cometary Nuclei
comet sun impact sun-grazing radiation collisions
2011/9/30
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...
Excursion Set Halo Mass Function and Bias in a Stochastic Barrier Model of Ellipsoidal Collapse
Excursion Set Function Stochastic Barrier Model Ellipsoidal Collapse
2011/9/29
We use the Excursion Set formalism to compute the properties of the halo mass distribution for a stochastic barrier model which encapsulates the main features of the ellipsoidal collapse of dark matte...
I summarize the statistical, physical, and morphological properties of coronal mass ejections (CMEs) of solar cycle 23, as observed by the Solar and Heliospheric Observatory (SOHO) mission. The SOHO d...
EUV and Coronagraphic Observations of Coronal Mass Ejections
Sun corona coronal mass ejections post-eruptive arcades filaments prominence
2010/9/16
The Large Angle Spectrometric Coronagraph (LASCO)and Extreme-ultraviolet Imaging Telescope (EIT) onboard Solar and Heliospheric Observatory (SOHO) provide us with unprecedented multiwavelength observa...
Magnetic Source Regions of Coronal Mass Ejections
Coronal mass ejection flare filament eruption
2010/9/16
The majority of flare activity arises in active regions which contain sunspots, while Coronal Mass Ejection (CME) activity can also originate from decaying active regions and even so-called quiet sola...
Solar Cycle Variation of Interplanetary Coronal Mass Ejection Latitudes
Sun activity coronal mass ejections (CMEs)
2010/9/15
With the use of interplanetary coronal mass ejections (ICMEs) compiled by Richardson and Cane from 1996 to 2007 and the associated coronal mass ejections (CMEs) observed by the Large Angle and Spectro...
