ROTATION-DEPENDENT CATASTROPHIC DISRUPTION OF GRAVITATIONAL AGGREGATES
minor planets asteroids:general planets and satellites:formation planets and satellites:physical evolution
2015/12/25
We carry out a systematic exploration of the effect of pre-impact rotation on the outcomes of low-speed collisions between planetesimals modeled as gravitational aggregates. We use pkdgrav, a cosmolog...
Asteroid rotation and shapes from numerical simulations of gravitational re-accumulation
Asteroids Asteroid formation Asteroid evolution Collisions
2015/12/25
We present simulations of the gravitational collapse of a mono-disperse set of spherical particles for studying shape and spin properties of re-accumulated members of asteroid families. Previous numer...
Fitting dwarf galaxy rotation curves with conformal gravity
Fitting dwarf galaxy rotation curves conformal gravity
2011/10/20
We continue our study of the application of the conformal gravity theory to galactic rotation curves. Previously we had studied a varied 111 spiral galaxy sample consisting of high surface brightness ...
Nonextensive distributions of rotation periods and diameters of asteroids
asteroids – rotation periods – diameters – nonextensivity
2011/10/21
Context. To investigate the distribution of periods of rotation of asteroids of different regions of the Solar System and distribution of diameters of near-Earth asteroids (NEAs). Aims. Verify if none...
Modeling of differential rotation in rapidly rotating solar-type stars
Modeling differential rotation rapidly rotating solar-type stars
2011/10/9
We investigate differential rotation in rapidly rotating solar-type stars by means of an axisymmetric mean field model that was previously applied to the sun. This allows us to calculate the latitudin...
