Fragment properties at the catastrophic disruption threshold:The effect of the parent body’s internal structure
Asteroids Collisional physics Asteroids, Composition
2015/12/25
Numerical simulations of asteroid breakups, including both the fragmentation of the parent body and the gravitational interactions between the fragments, have allowed us to reproduce successfully the ...
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...
Physical Structure of the Planetary Nebula NGC 3242 from the Hot Bubble to the Nebular Envelope
Physical Structure Planetary Nebul Hot Bubble Nebular Envelope
2011/10/12
One key feature of the interacting stellar winds model of the formation of planetary nebulae (PNe) is the presence of shock-heated stellar wind confined in the central cavities of PNe. This so-called ...
Height structure of X-ray, EUV and white-light emission in a solar flare
Sun: fl ares – Sun: X-rays, gamma-rays – Sun: radio radiation – Sun: UV radiation – Acceleration of particles
2011/10/11
The bulk of solar flare emission originates from very compact sources located in the lower solar atmosphere and seen in various wavelength ranges: near optical, UV, EUV, soft and hard X-rays, and gamm...
Dynamical Opacity-Sampling Models of Mira Variables. II: Time-Dependent Atmospheric Structure and Observable Properties of 4 M-Type Model Series
stars: AGB and post-AGB, stars: atmospheres, stars: variables: other, stars: mass loss
2011/10/11
We present 4 model series of the CODEX dynamical opacity-sampling models of Mira variables with solar abundances, designed to have parameters similar to $o$ Cet, R Leo and R Cas. We demonstrate that t...
